You are in your room listening to music and, realize you are thirsty, you can feel that your soda is no longer cold, and you decide to invite a friend over. What parts of the central nervous system would be primarily involved in each of these italicized behaviors

Internal region of the brain and the hypothalamus are related to the sensation of thirst.

Thalamus is involved with the perception that the soda is not colder.

Explanation:

The central nervous system is the body system responsible for making your body receive information and respond appropriately, promoting full bodily functioning. It is formed by the brain, spinal cord and the components that form them.

Regarding the activities shown in the question above, we can say that some components of the brain are related. For example: The innermost part of the brain and the hypothalamus are related to feeling thirsty. This is because the inner part of the brain is responsible for making the brain understand how the organism is functioning, if something is missing or if there is any discomfort that needs to be resolved. The hypothalamus, in turn, is responsible for the release of hormones that signal that your body's homeostasis is unbalanced. With the interaction of these two structures you realize that you are thirsty.

In addition, the thalamus is responsible for allowing your body to receive sensory messages. It is this structure that allows you to realize that your soda is not cold when you touch the glass, or take a sip of it.
