Definitions:

Simple Cortical Cells

Neurons in the visual cortex that respond best to edges and bars of light with a specific orientation, playing a fundamental role in visual processing.

Hypercomplex Cortical Cells

Neurons in the visual cortex involved in processing complex visual stimuli, such as the movement and length of objects.

Lateral Geniculate Cells

Neurons located in the lateral geniculate nucleus of the thalamus, playing a crucial role in visual processing by receiving signals from the retina and relaying them to the visual cortex.

On-center Cells

Neurons in the visual system that are excited by light falling on the center of their receptive field and inhibited by light falling in the surrounding area.
