Physiological and Psychological Processes:
It's the portion of the brain responsible for most complex behaviors and higher mental processes. It's also the last structure in the nervous system to develop, both in terms of evolution and individual development.
• Corpus Callosum
• Cerebral Cortex
• Cerebellum
• Reticular Formation

Answer 1

The portion of the brain responsible for most complex behaviors and higher mental processes is the **Cerebral Cortex**.

The cerebral cortex is involved in various higher brain functions, including thought, reasoning, language, and decision-making. It is also the last structure in the nervous system to develop, both in terms of evolutionary history and individual growth during childhood.

In contrast, the other options serve different functions:

- **Corpus Callosum**: Connects the left and right hemispheres of the brain and facilitates communication between them.
- **Cerebellum**: Coordinates voluntary movements, balance, and motor skills.
- **Reticular Formation**: Plays a crucial role in regulating wakefulness and sleep-wake transitions.

Therefore, the correct answer is **Cerebral Cortex**.
