Answer:
All processing at the circuit level going up to the perceptual level must synapse in the thalamus.
Step-by-step explanation:
Most sensory information reaches the cerebral cortex after passing through the thalamus. Since we depend critically on the activity of our senses to relate to the outside world, we can consider the thalamus as a key piece in perception.
The thalamus is a small structure inside the brain and is located in the upper part of the brain stem, it facilitates the integration of sensory information through projection neurons that aim to communicate with other areas, such as the cortex, that is, it responsible for the analysis and integration of sensitive functions.
