What Does Each Do?

A neurobiologist is a scientist who studies the brain.

These scientists use a variety of techniques to learn new information about the brain. Each new piece of information they learn is a step closer to understanding the brain more.

Some neurobiologists study the structure and organization of the brain. Others study the chemistry of the brain.

How can a neurobiologist study the brain?

By lowering very fine wires called electrodes into the brain of a living person, it is possible to record the nerve impulse sent by a single neuron.

Electrodes

​Neurobiologists can visualize brain cells by cutting brain tissue into extremely thin slices. They use dyes to stain the slices so that the cell parts can be seen with a microscope.

Brain Tissue

​The abbreviation MRI stands for magnetic resonance imaging. One type of MRI that is used by neurobiologists to study brain activity is an fMRI, or functional magnetic resonance imaging.

Neurobiologists have found that the left side of the cerebral cortex is connected to the right side of the body, and the right cerebral cortex is connected to the left side of the body.

Through mapping, scientists are able to understand the brain better.
