Definitions:

Bipolar Cells

Cells in the retina that act as a relay between photoreceptors and ganglion cells, transferring visual information.

Ganglion Cells

Neurons located in the retina that receive visual information from photoreceptors via bipolar cells and transmit it to the brain through the optic nerve.

Neurons

Neurons are the fundamental units of the brain and nervous system, responsible for receiving, processing, and transmitting information through electrical and chemical signals.

Equal Intensities

A term often used in the study of sensory perception, describing stimuli that have the same level of strength or magnitude but can vary in type.
