Which part of the brain is responsible for automatic survival functions?

The brainstem is primarily responsible for regulating automatic survival functions. This region of the brain controls critical functions such as heart rate, breathing, and blood pressure, all of which are essential for maintaining life without conscious effort. The brainstem acts as a vital connection between the brain and the spinal cord, coordinating reflexes and various involuntary actions.

In contrast, the cerebrum is involved in higher-order functions such as thinking, learning, and memory. The cerebellum is mainly responsible for coordinating voluntary movements and balance, while the thalamus acts as a relay station for sensory information before it reaches the cerebral cortex. Each of these parts of the brain has distinct roles, but the brainstem is uniquely situated to handle the automatic processes crucial for survival.
