Brain Blueprints: Sensory Perception
Sensory perception enables us to perceive and interact with the world around us including ourselves. It begins with the reception of sensory information from the environment & our own body and ends with the mostly conscious awareness of these stimuli.
In this article, I’ll try to extract and overview the basic system as part of the Brain Blueprints Project.

Skin Receptors
Your skin is a complex organ, roughly the size of a queen-sized bed which houses approximately 5 million cutaneous receptors. These receptors are responsible for detecting environmental stimuli such as temperature, pressure, and pain. Rather than sending this information directly to the cortex, the receptors first route it to the thalamus, which modulates and enhances the sensory information before it is processed by the brain.
Thalamus, small but mighty.
The Thalamus, while modest in size with an estimated 80 million neurons, plays a crucial…
