Questions on the hypothalamus and thalamus and brain stem in the brain?

Question

1. why do we have a hypothalamus?

2. what is the role of the thalamus?

3. brain stem injuries can result in a person stopping breathing. why could this be the case?

Answer 1

The hypothalamus is responsible for regulatory and motivated behaviors including:

temperature regulation; reproduction; eating; drinking; cardiac functions; hormonal release; fight or flight response

The thalamus functions as a relay center for incoming sensory information. It directs these sensory impulses to the appropriate brain area for processing.

The brain stem contains the medulla which in part controls respiration (breathing)
