Brain mapping (aka neuroimaging) is a technique used to visualize and understand the structure and function of the brain. There are various methods for brain mapping, each providing different types of information about the brain’s anatomy, connectivity, and activity. 

Let’s take a look at several techniques used in most brain mapping sessions and procedures.

Structural Imaging

Structural MRI (Magnetic Resonance Imaging) provides detailed images of the brain’s anatomy, allowing for the visualization of different brain regions, white matter tracts, and abnormalities. High-resolution structural MRI scans can help create detailed three-dimensional maps of the brain.

Functional Imaging

There are two types of functional imaging that are commonly used in brain mapping: 

Functional Magnetic Resonance Imaging

fMRI measures changes in blood flow and oxygenation levels in the brain, providing information about brain activity. This technique is commonly used to identify activated regions during specific tasks or at rest, helping to create functional maps of the brain.

Positron Emission Tomography

PET involves injecting a small amount of a radioactive substance into the body. As the substance decays, it emits positrons that can be detected by the scanner. By tracing the distribution of the substance, PET can provide information about regional cerebral blood flow, glucose metabolism, and neurotransmitter activity.

Electrophysiological Mapping

There are two types of Electrophysiological Mapping that are commonly used in brain mapping: 

Electroencephalography (EEG)

EEG measures electrical activity in the brain using electrodes placed on the scalp. It is often used to assess brain function in real-time, such as monitoring sleep patterns, identifying epileptic activity, or investigating cognitive processes.

Magnetoencephalography (MEG)

MEG measures the magnetic fields generated by neuronal activity. It provides high temporal resolution and is used to localize brain activity with a level of precision similar to EEG.

Diffusion Imaging

DTI (Diffusion Tensor Imaging) is a type of MRI that maps the diffusion of water molecules in brain tissues. It is particularly useful for visualizing white matter tracts and understanding the structural connectivity of different brain regions.

Connectivity Mapping

There are two types of connectivity mapping that are commonly used in brain mapping: 

Resting-State fMRI

This technique examines spontaneous fluctuations in blood oxygenation levels when the brain is at rest. It is used to identify functional connectivity patterns, revealing how different brain regions are synchronized and communicate with each other.


Tractography, often derived from DTI, maps the pathways of white matter tracts in the brain, providing insights into structural connectivity between different brain regions.

Neuropsychological Mapping

In cases of brain injury or disease, lesion mapping involves identifying the location and extent of damage to different brain structures. This information helps correlate brain regions with specific cognitive or motor functions.

Brain Stimulation Mapping

Transcranial Magnetic Stimulation (TMS) involves applying a magnetic field to specific areas of the scalp, temporarily disrupting neural activity. By observing the resulting effects on behavior or cognitive functions, researchers can map the functional contributions of different brain regions.

Brain Mapping Combination

Brain mapping techniques are often used in combination to provide a comprehensive understanding of the brain’s structure and function. Advances in neuroimaging technologies continue to refine our ability to map the intricacies of the brain, contributing to our understanding of neurological disorders, cognitive processes, and brain function.

What Our Clients Are Saying

Julia W

Teachers made huge comments on his math skills and behavior. I also saw this at home with understanding of what I said to him registering more with him. I saw this in his eyes: recognition. Fewer outbursts of anger.

Anita M

I am extremely happy with my son’s outcomes and feel very fortunate to have encountered Dr. Bonesteel early in my child’s life. This method has dramatically changed his ability to focus and take initiative. I feel confident that my son’s life has been dramatically enhanced. I can’t express my appreciation fully in words.

Mary B

Dr. Bonesteel has masterfully, compassionately, and extremely kindly helped me navigate through a history of childhood and marital abuse, a child with twenty years of struggle with life-threatening physical and emotional illness, extended family discord, and disharmony with my child with severe depression. I am blessed to have found Neurohealth Associates.


Overall, excellent experience. Very happy with Dr B and staff is wonderful. We feel like we have our family life back!


I am very thankful this technology was available for my training. I was extremely satisfied with all aspects of my training protocols.
