These cells coordinate bodily functions and movement quickly, often without intentional thought. They also can be affected differently by health conditions. Talk with your healthcare provider if you ...

The work, which was done in mice, also shows these specialized T cells play a role in nerve-cell development and memory formation. The findings shed light on brain immunity and could pave the way to ...

Our nerve cells, or neurons, communicate by sending fast electrical signals called action potentials. These signals always begin in a specific part of the neuron known as the axon initial segment (AIS ...

Jan. 31, 2024 — To rapidly transmit electrical signals in the brain, the long nerve fibers are insulated by specialized cells called oligodendrocytes. These cells also respond to the electrical ...

Myelin is an insulating layer of lipids and proteins surrounding nerves. Myelin damage can cause problems with the nerves’ ability to send and receive electrical messages. Inflammatory disorders ...

The integration of experimental evidence, a robust mathematical framework and computer simulations convincingly demonstrate the effects of action potential propagation ... coupling at the well-studied ...
