Definitions:

Cerebral Cortex

The outer layer of neural tissue of the cerebrum of the brain in humans and other mammals, responsible for higher brain functions, including sensation, voluntary muscle movement, thought, reasoning, and memory.

Phasic Receptors

Sensory receptors that detect changes in stimulus intensity, adapting quickly and only responding to the onset and cessation of stimuli.

Primary Receptors

Sensory cells or nerve endings that respond directly to stimuli from the environment, such as light, sound, or chemicals.

Secondary Receptors

Molecules or structures in cells that detect signals from primary receptors and help propagate the signal inside the cell, often involved in signal amplification.
