In a recent interview, I had the pleasure of speaking with Dr. Andrew Hill from the Peak Brain Institute. Dr. Hill holds a Ph.D. in Cognitive Neuroscience from UCLA and specializes in neurofeedback and brain mapping.

Brain mapping is the process of creating a visual representation of the brain's activity, typically through imaging techniques such as functional magnetic resonance imaging (fMRI) or electroencephalography (EEG). This allows researchers and clinicians to identify specific areas of the brain that are active during certain tasks or in response to certain stimuli.

Neurofeedback, also known as EEG biofeedback, is a type of biofeedback that uses EEG to provide real-time feedback to the individual about their brain activity. This allows the individual to learn to control specific aspects of their brain activity, such as the activity in a specific brain region or the frequency of their brain waves. This can be used for a variety of purposes, including to improve cognitive function, reduce symptoms of disorders such as ADHD or anxiety, or to enhance performance in sports or other activities.

Dr. Hill began his work in the field of mental health and human resources, and his early research focused on using neurofeedback to help children with autism, seizures, ADHD, and other issues. The core of his business at the Peak Brain Institute utilizes modalities such as EEG, QEEG, and ERP to map the brain and understand its activity.

During our conversation, Dr. Hill delved into the different waves of the brain and the role they play in our overall well-being. He explained how he started to create a control group to score others in his brain mapping, and how he began to see similarities in people who were higher or lower in specific brain waves. He discussed the different types of brain waves such as theta, beta, and alpha, and how these waves can be used to help with different ailments.


To help you understand, check out the different waves and what they are responsible for:

Gamma waves (30-100 Hz) - These waves are associated with high cognitive functions, such as problem-solving and memory. They are also linked to heightened states of consciousness and awareness.

Beta waves (12-30 Hz) - These waves are associated with normal waking consciousness and active thinking. They are typically present during tasks that require attention and focus.

Alpha waves (8-12 Hz) - These waves are associated with a state of relaxation and calm, such as when someone is meditating or daydreaming. They are also linked to creativity and intuition.

Theta waves (4-8 Hz) - These waves are associated with deep relaxation, such as when someone is in a deep sleep or in a trance-like state. They are also linked to memory and emotional processing.

Delta waves (0.5-4 Hz) - These waves are associated with deep sleep and are typically present during the first stage of sleep. They are also linked to the regulation of bodily functions such as heart rate and blood pressure.

Epsilon waves ( < 0.5 Hz) - These waves are associated with very deep sleep and an anesthetized state. They are also linked to the regulation of bodily functions such as heart rate and blood pressure.


One of the key benefits of brain mapping and making these changes is the ability to lower anxiety and help with depression. Additionally, Dr. Hill discussed how neurofeedback can improve mental focus and help individuals overcome unhealthy habits. He also spoke about the importance of giving real cognitive tests that people can work on to change their brain waves in order to achieve these benefits.

Overall, Dr. Hill's work at the Peak Brain Institute is focused on using the latest technology and research to help individuals achieve optimal brain function and improve their overall well-being. It's exciting to see the advancements in this field and the potential for neurofeedback to improve the lives of so many people.  This was part 1 of 3 of my interview with Dr. Hill.  If you are at all interested in this material, check out the rest of the interview on my podcast.
