Q

How does perception differ from sensation?

A

Perception is the brain’s ability to interpret and make sense of sensory input, allowing us to recognize and identify stimuli.

Q

How does the tactile (or somatosensory) system work?

A

The tactile system involves skin receptors detecting pressure, temperature, and pain. Specific receptors include Meissner’s corpuscles (sensitive touch), Merkel’s discs (light pressure), Ruffini’s end-organs (heavy pressure), and Pacinian corpuscles (vibrations).
