Today, Dr. Curtis Cripe takes a break from discussing neuroengineering and delves into a mysterious and fascinating phenomenon — the Doorway Effect.

Passing through doorways has a profound effect on memory. Take, for instance, when you go to the kitchen to get something from the cupboard. As you pass through the doorway, you suddenly forget what you intended to do initially. Psychologists call this the Doorway Effect.

Studies have determined that doorways represent the boundary between one context to another. By context, the studies suggest rooms where a person moves, passing through a doorway. The so-called boundary, in this context, helps segment thoughts and experiences into separate events as though, in your mind, these are being partitioned for later use.

In some ways, Dr. Curtis Cripe explains that these boundaries help define what could be relevant in one situation from what could be relevant to another.

That said, when you move from one room to another, there is a likelihood that the relevant information from a previous room may be lost. It may either be replaced or flushed out by the relevant idea in the next one.

In the end, the doorway effect refers to how people remember things. It points to the fact that there’s more to remember than what people are paying attention to when it happens. But then, there’s also the effort to keep the memories.

Dr. Curtis Cripe adds that the brain seems to optimize some forms of memory to keep the information ready to hand when it expires and then shred that information when a new one is ready.

Dr. Curtis Cripe Looks at Neuroscience and Engineering

Dr. Curtis Cripe: How Neuroengineering Came to Be


In the field of medicine, Dr. Curtis Cripe explains that very few things intrigue people as much as the human brain. He has mentioned how research on it has garnered more attention than almost any topic. This is one reason Dr. Curtis Cripe, along with many other experts, believes that neuroengineering deserves to be in the spotlight.

The history of neuroengineering is quite fascinating. It is a field that combines engineering techniques and the science of the neural system. Reading about it, you may feel that it is almost as if many of the events were taken from a science fiction novel or movie. This has become even more true in recent years. Recently, leading researchers in the field have been able to create interfaces and facilitate interaction between the human neural system and non-living constructs. That in itself is mind-boggling, to say the least.

Neuroengineering as a discipline began a bit later than other research fields. Dr. Curtis Cripe explains that this is mainly because the technology required to accomplish what researchers set out to do had not yet been developed.


Researchers have indeed made significant strides in neuroengineering. That said, there is still so much to be learned about the human brain and whatever innovation can interact with it.

The first global conference on neuroengineering took place in 2003. In 2004, extensive journals and reports were published on the subject. Today, Dr. Curtis Cripe says that neuroengineers worldwide get together regularly. In these meetings, they discuss findings, compare notes, and push the field forward.

Dr. Curtis Cripe on Four Types of Developmental Delays

Dr. Curtis Cripe Explains Different Developmental Delays in Children


Dr. Curtis Cripe’s research on neuroengineering touches on cognitive disorders and neurodevelopmental delays. In this blog post, Dr. Cripe discusses four types of developmental delays parents should be aware of.


On speech delays

Children with speech delays will have trouble understanding words or concepts. They may even have a limited vocabulary for their age. Those with this type of speech delay may take longer to babble, speak, and form complete sentences. They might also exhibit both expressive and receptive difficulties. Oral motor or other physiological issues can potentially contribute to speech delays.

On cognitive delays

Children with cognitive delays experience difficulties in reasoning and problem-solving. This may lead to learning and comprehension challenges that become apparent when a child goes to school or socializes with others.

On socioemotional delays

Struggling to comprehend social cues, initiate or maintain dialogues, or manage disappointment can signify socioemotional delay. Children also struggle to handle emotionally and socially difficult situations. One potential sign is when a baby doesn’t point or respond to words, smiles, or signals from parents. Dr. Curtis Cripe says another indication is when a child exhibits a fear of unfamiliar faces.

On motor delays

Motor skill delays can be seen in a child’s inability to use major muscle groups, like the arms and legs. A weakness with smaller muscle groups, such as the hands, can also be seen. Gross motor delays can pose a challenge for infants to roll over or crawl. It can also make older children appear awkward, especially when doing usual movements. Children with fine motor delays will have trouble grasping small objects like toys and doing common tasks like tying shoes or brushing their teeth.

A child’s brain goes through a specific development period from infancy to toddlerhood. Various factors, including the child’s interactions and surroundings, impact development. Parents and other adults should monitor their child’s growth to address potential delays.

What Makes Brain Mapping Important


Understanding the brain has been treated with foremost importance by neuro engineers like Dr. Curtis Cripe. It has not proven to be easy, especially considering that the human brain is a collection of 100 billion neurons and support cells.

The human brain is quite intriguing in that it can store decades’ worth of memories and be used to build something as small as microchips and as complex as space stations. But have you ever wondered how humans are much more intelligent than animals with bigger brains, such as sperm whales and elephants? Such is the intricacy of the human brain. Scientists have been developing ways to study the organ for a long time. Brain mapping has proven to be helpful in this pursuit.


It is a collection of various tools that gives a thorough picture of the brain structure. Dr. Curtis Cripe lists some of the key benefits of brain mapping.

One of the most common use cases of the technology is helping doctors, neuro engineers, and medical professionals plan safe surgeries. For instance, one method of treating epilepsy requires removing an affected part of the brain. Through brain mapping tools, such as functional MRI and EEG, surgeons can determine where the seizure center is.

Similarly, brain mapping can also be used to diagnose neurodegenerative diseases, such as Parkinson’s and Alzheimer’s. For example, MRI can be used as a tagging technique to examine shrinkages in some parts of the brain, which could indicate tissue loss.

Brain mapping can also aid in identifying the possible root cause of any psychological or physiological symptoms that a patient may be experiencing. With more and more people suffering from mental health conditions like anxiety and depression nowadays, medical professionals are given an effective tool to understand how and why a patient is struggling with the symptoms of the conditions.

What is Psychological Resilience, and How Can You Improve It?


According to Dr. Curtis Cripe, a neuroengineer involved in developing advanced technology for brain and cognitive repair, the brain is the only organ in the body that has no capability of healing itself after sustaining an injury. On the other hand, the brain can adapt and relearn quickly. One of the reasons the brain has coping abilities is psychological resilience.

Psychological resilience is a multi-dimensional construct representing how a person can adapt and respond positively to adversity and sustain proper mental health. Another way to define it is the ability to psychologically handle a crisis and return to a pre-crisis condition in just a short while.

The American Psychological Association explains it as the process of good adaptation or coping in the event of hardship, trauma, tragedy, and other significant sources of stress. Various interacting factors contribute to an individual’s psychological resilience, including genetics, epigenetics, childhood developmental environment, cognitive abilities, and other psychosocial factors. Too much stress and adversity can also impact a person’s psychological resilience because of the lack of coping skills or neurophysiological strength.

Fortunately, there is a way to improve your psychological resilience, says Dr. Curtis Cripe.

One such way is to help one’s fluid intelligence continue to act amid stressful conditions. Fluid intelligence is a person’s ability to solve problems unrelated to the knowledge they have previously acquired.


Another way to boost psychological resilience is learning positive coping styles in the face of troubles. A study on Chinese students determined a correlation between positive coping style and three psychological resilience components: mood control, self-plasticity, and coping flexibility.

Dr. Curtis Cripe currently serves as the director of research and development of NTL Group, a firm that combines the various fields of neuroscience, engineering, neurology, psychology, and others with the intent of advancing methodologies for recording, scanning, imaging, and analyzing brain activity.

The Possible Effects of Long-duration Space Travel on the Brain


Achieving spaceflight has allowed humans to explore and understand the solar system and the rest of the universe. But spaceflight is not as glamorous as it seems; rather, it comes with a lot of risks and financial costs. On top of that, Dr. Curtis Cripe notes that staying in space for a long duration can even affect an astronaut’s brain.

The human brain is a complex organ. To put it simply, it controls how the entire body functions. Studying how the brain adapts to various environments and situations, including during spaceflight, is important. After all, there are plenty of hazards in the space environment to which astronauts are subjected. These include altered gravity fields for a prolonged time, radiation, ICE (isolated/confined/extreme) conditions, lack of healthy sustenance, and more.

Researchers have been trying to understand how long-duration spaceflight can impact the microstructures of the brain’s wiring. As Dr. Curtis Cripe explains, prolonged exposure to the space environment can change the makeup of the white matter, which is the part of the brain that helps the organ relay information and signals efficiently.


A recent study was conducted on astronauts who had extended tours of duty at the International Space Station. Their brain scans before and after the spaceflight were collected and compared to a control group that accounted for the participants’ physical attributes. For instance, individuals of the same age, gender, and handedness as the participants were chosen. The comparisons between the brain scans showed that microstructural changes in some parts linked with the brain’s sensorimotor tracts, such as the area that connects the two halves of the organ (corpus callosum), occurred. Some changes in the cerebellum were also discovered. While these changes have been documented, the potential long-term effects of long-duration spaceflights are still being studied.

Dr. Curtis Cripe is a neuroengineer with a diverse multidisciplinary background that has been developing brain-based technology and programs that can be used to provide countermeasures for neurochanges that may occur in space. Read more about him here.

Reviewing Brain Plasticity With NTL Group’s Dr. Curtis Cripe


The brain has a lot of remarkable qualities and abilities, says NTL Group’s Dr. Curtis Cripe. One of these is called neuroplasticity or brain plasticity. Plasticity is the brain’s or any complex organ’s ability to change through time. For example, the central nervous system can change and adapt amidst certain external stimulation. This is the same concept behind restoring damaged areas in the brain, which help it heal from injury.

Brain plasticity begins before the baby is born, as the brain starts to organize itself. It also occurs as a healing response when the brain is injured. Brain plasticity exists for the brain to compensate for lost functions or improve those that remain. It also happens during adulthood as one learns or memorizes new concepts and ideas. Dr. Curtis Cripe points out that plasticity occurs as long as the brain learns.


Researchers have further found that when it comes to neural connections in the brain, many damaged cells can lead to or result in the creation of new connections. This is called synaptic reorganization, which is the basis for brain plasticity. For this to happen, though, the brain and the nervous system need external stimulation to achieve either development or recovery from trauma or addiction.

This is a very important process based on scientific findings. With the right circumstances, Dr. Curtis Cripe says that neuroplasticity can help an adult mind grow. With specific brain functions inevitably falling apart with age, there are still things that the brain can fix through brain plasticity. Furthermore, this can be accomplished through targeted brain exercises and re-training the brain, easing it back to health. This is significant information, especially for people with cognitive conditions such as dementia and schizophrenia, notes Dr. Curtis Cripe.

BrainOorganization: What is the Reticular System of the Brain?


The reticular system of the brain is a network of interconnected neurons that extends from the medulla oblongata to the thalamus. This system regulates many vital functions, including wakefulness, attention, and motor control.

Dr. Curtis Cripe, head of NTL Group’s research and development team, notes that the reticular system is divided into two main regions: the ascending reticular activating system (ARAS) and the descending reticular inhibiting system (DIRS). The ARAS is responsible for promoting wakefulness and alertness, while the DIRS regulates sleep and relaxation.

The reticular system plays a key role in the brain’s reward system. This system is responsible for releasing dopamine, a neurotransmitter associated with pleasure and motivation. The dopamine release in the reward system makes activities such as eating, sex, and exercise pleasurable.

Dopamine plays a major role in addiction and substance abuse. Drugs of abuse, such as cocaine and heroin, cause a large release of dopamine in the brain’s reward system. This leads to the feeling of euphoria that is often associated with drug use.

The reticular system is also involved in learning and memory. It has been shown to be necessary for the formation of new memories, as well as the consolidation of old ones.


Common problems with the reticular system include sleep disorders, attention deficit hyperactivity disorder (ADHD), and addiction. Treatment for these conditions often focuses on correcting the underlying imbalance in the brain’s neurotransmitters.

Specialists who research the reticular system are called neuroscientists. They use a variety of tools and techniques to study the brain. These include functional magnetic resonance imaging (fMRI), positron emission tomography (PET), and transcranial magnetic stimulation (TMS).

According to Dr. Curtis Cripe, neuroscientists are constantly working to better understand the brain and its many complex functions. By studying the reticular system, they hope to develop better treatments for conditions that affect the brain.

The Human Brain And Beyond: What Is Brain Plasticity?

In neurological terms, plasticity refers to the brain’s ability to change and adapt in response to experience. Dr. Curtis Cripe mentions that brain plasticity allows us to improve our brain function by doing things that challenge and help us learn new things.


There are two main types of brain plasticity:

Neuroplasticity: This is the brain’s ability to change its structure and function in response to experience. This type of plasticity occurs throughout our lives but is particularly important during development when the brain grows and changes the most.

Cognitive plasticity: This refers to the brain’s ability to learn new information and skills and make new connections between different areas of the brain. This type of plasticity is essential for learning new things and keeping our brains healthy as we age.

While brain plasticity is a complex process that is not yet fully understood, Dr. Curtis Cripe explains that it is influenced by many factors, including genes, environment, and lifestyle.

There are many ways to improve brain plasticity. Some of the most effective methods include:

Physical activity: Physical activity increases blood flow to the brain, which helps nourish and protect brain cells. It also promotes the growth of new nerve cells and connections in the brain.

Cognitive stimulation: Challenging the brain with new activities and experiences, such as venturing into a new hobby, learning a new language, or doing puzzles and brain teasers, can help improve brain plasticity.

Sleep: Sleep helps consolidate memories and allows the brain to repair and regenerate cells, notes Dr. Curtis Cripe.

Nutrition: Subscribing to a balanced and nutritious diet is vital for all aspects of health, including brain health. Eating plenty of fruits, vegetables, and food rich in omega-3 fatty acids is beneficial for brain plasticity.

Stress management: Managing stress is essential for overall health and well-being, and it can help improve brain plasticity. Some ways to manage stress include relaxation techniques, exercise, and getting enough sleep.
