Definitions:

Schwann Cells

Specialized cells in the peripheral nervous system that wrap around nerve fibers, providing electrical insulation and helping in the regeneration of damaged nerves.

Oligodendrocytes

Glial cells in the central nervous system that produce myelin, the insulating layer around neurons.

Reverberating Circuits

A neural circuit in which signals travel in a loop, often used to control rhythmic activities such as breathing.

Action Potentials

Action Potentials are rapid, temporary changes in the electrical membrane potential of cells, crucial for nerve signal transmission and muscle contraction.
