Document Summary
Psyc 101 lecture 8 sensations and perceptions 1. Send the encoded information to the brain. Encoding translation of the physical properties of a stimulus into a specific pattern of neural activity. Information is sent to the hypothalamus to be processed and sent to the specialized areas: step five, cerebral cortex receives the information and produces sensations and perceptions.
