Definitions:

Hypercomplex Cortical Cells

Neurons in the visual cortex that respond to specific characteristics of visual stimuli, such as the length or angle of an object.

Lateral Geniculate Cells

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

Simple Cortical Cells

Neurons in the visual cortex that respond preferentially to stimuli of a specific orientation in a small localized area.

Complex Cortical Cells

Complex cortical cells are neurons found in the visual cortex that respond optimally to specific visual stimuli, such as movement in a particular direction.
