👉 The Thalamic Cortical System (TCS) is a region of the brain that includes the thalamus, which is located in the brainstem and controls sensory perception, motor control, and sleep-wake cycles.

The TCS also plays a crucial role in regulating the sleep-wake cycle by controlling the release of hormones such as melatonin, which regulates sleep
