Definitions:

Resting Potential

The electrical charge difference across the cell membrane while a neuron is at rest, typically around -70mV, enabling the potential for action potentials.

Action Potential

A rapid increase and subsequent decrease in voltage across a cellular membrane, allowing neurons and muscle cells to communicate and react to stimuli.

Convergence

The evolutionary process where organisms from different evolutionary backgrounds develop similar traits or features in response to similar environmental challenges or functional needs.

Typical Neuron

A cell of the nervous system, characterized by its ability to receive and transmit electrical signals throughout the body.
