What exactly is brain mapping?
Brain mapping can capture a window of brain activity. The brain is a multi-billion neuron organ. Neurons communicate with every cell in your body. It is carried by electrical impulses that form brain waves. This application helps us analyze your brainwaves and find ways to improve communication across different brain regions.

How Brain Mapping Works
The human brain has around 100 billion neurons and supporting cells. It can write sonnets and build planes. Elephants’ brains are bigger, heavier, and have more neurons than ours, but they lack talent. Intrigued? Scientists are. That’s why they’re mapping the human brain, a task that could take decades.
Brain mapping seeks to connect the brain’s anatomy to function, or which areas give us certain talents. What area of our brain allows us to be creative or logical? It’s called functional localization.
When mapping brain function, scientists use imaging to watch the brain in action. Charles Wilson, a neurobiologist at UTSA, explains how the function is localized:
There are parts of the brain that deal with vision and others with sound. Can we ask whether there is a section of the brain that recognizes red items and another that recognizes green stuff? Or does the same area detect both?
what happens in the brain during mental diseases?
Brain mapping also analyzes the brain from the outside. It studies how our environment impacts our brain structure, such as how the brain changes through learning and aging. Brain mapping also examines what happens in the brain during mental diseases and other brain disorders.
Finally, brain mapping aims to provide a comprehensive picture of our brain. Our earth shows in Google Earth via satellite photos, and we can zoom in on continents and countries. A full brain structure map would look like this. An fMRI might show us our complete brain: regions, functional lobes, specialized centers, thick neuron “bundles” connecting brain sections, neuron circuits, and single neurons. Scientists are still working on the components of this massive atlas.
Brain mapping is a term that relates to many tools. Researchers must acquire brain images, translate them to data, and then analyze brain development.
Brain Mapping Tools and Techniques
Scientists use several methods to study the brain’s anatomy and function. They photograph healthy and sick brains. also, Scientists study human, monkey, and micro mammalian brains to learn more about invertebrates’ neural systems. They study small neurons as well.
Here are several tools for brain mapping. It provides brain images:
CAT scans the brain from multiple angles, identifying structural abnormalities.
It uses the brain’s water to produce images with higher resolution than a CT scan.
Diffusion tensor MRI (DTI) shows “tracts” of neurons connecting brain areas by detecting water movement.

Why would scientists bother to map the human
brain? The solution, according to Lichtman, is to
better understand our brains. We’ve never seen
a diagram showing all of the brain’s
connections. So we want to see what’s truly
there.
The brain’s wiring structure may help us
comprehend how people learn and adapt,
says Lichtman. By adulthood, we can use
devices that our genetic inheritance could
never teach our neurological system, like
iPods. No other animal can do this. To use
these devices, we must connect ourselves
during development.”

How Brain
Mapping helps
Doctors?
Brain mapping can help doctors. Brain mapping is used by
neurosurgeons to assure patient safety. For example, one
treatment for epilepsy involves brain removal. Using functional
MRI and electroencephalography, surgeons can determine a
patient’s seizure center as well as active speech and movement
areas. These visuals show doctors what to preserve and what to
discard.
Brain imaging isn’t just for the diagnosis. It is used to diagnose
neurodegenerative diseases including Parkinson’s and
Alzheimer’s [source: Wilson]. Doctors may use PET or MRI to tag
brain chemicals or to search for shrinkage in areas of tissue loss.
Researchers can track changes in the brain as diseases progress
or treatments work [source: Institute for Neurodegenerative
Disorders].

Autisme and other
developmental issues may have
structural brain roots
Autisme and other developmental issues
may have structural brain roots. Autism,
according to Lichtman, is caused by faulty
neuronal connections. Using Brainbow on
an autistic mouse, researchers can track
the wiring diagram’s evolution to see when
and if it breaks.
Researchers have also tried to show how
various mental illnesses affect the brain,
with varying degrees of success. These
patients’ MRIs revealed structural
abnormalities. Schizophrenic individuals
lose matter in their temporal and
prefrontal brain, for example (Rapoport).
These findings have yet to lead to therapy.
Brain imaging is utilized to study
panic disorder, bipolar disorder,
depression, anxiety, and eating
disorders, but how do we interpret
the results? Where can we see them?
