In short, this is how an electrical signal is generated in the neurons. Traditional electricity is generated by the motion of free electrons, but the electricity generated by neurons results from the motion of sodium and potassium ions across the cell membrane. Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances. Brain damage is an injury that causes the destruction or deterioration of brain cells. ft.

The goal of this study is to define and explore cell type-specific gene expression patterns via a meta. Glial cells provide support. The altered huntingtin then interacts with various proteins in nerve cells and causes the nerve cells of people with HD to become very sensitive to glutamate. Recent research has suggested that glia can be prompted to produce neurons in some models of brain injury or after genetic manipulation. Here's my answer: #1 Live a brain-healthy lifestyle first (Be Brain Fit tells you how). Now director of the Center for Neuroscience at the University of California, Davis, McAllister continues to investigate how the brain’s nerve cells — called neurons — find each other, connect and disengage. Elite Member. The major distinction is that glia do not participate directly in synaptic interactions and electrical signaling, although their supportive functions help define synaptic contacts and maintain the signaling abilities of neurons. Neurotransmitters are chemical messengers that carry, boost, and balance signals between neurons (also known as nerve cells) and target cells throughout the body.
