Introduction
Biological communication occurs at many levels, from one cell communication with its neighbour in a tissue (paracrine, to signals released into the blood from one cell to signal to another cell or tissue (endocrine or hormone signaling). The signalling that occurs in the brain, spinal cord and other nervous tissues involves electrical (action potentials) signaling.
This page will introduce development of signaling in our special sensory nervous systems: the eyes for vision and the ears for hearing. Both systems convert signals in one medium (light or sound) into an electrical signal that our brain can understand.
