The hindbrain has three structures the medulla, pons, and cerebellum. The medulla reulates heart beat and respiration. The pons plays a role in respiration, consciousness, sleep, dreaming, facial movement, sensory processes, and the trans mission of neural signals from one part of the brain to another. Finally, the cerebellum is required for balance, muscle tone, and motor skills.
The midbrain connects the structures of the hindbrain and forebrain. It contains the reticular formation which reulates arousal and plays an imprtant roles in attention, sleep, and consciousness.
The forebrain regulates complex mental processes. The first structure of the forebrain that the book discusses is the limbic system. The limbic system is a system of structures including the amygdala(plays a role in fear and agression) and the hippocampus(plays a role in the transfer of information for short-term to long-term memory) that govern certain spects of emotion, motivation, and memory. Two other structures in the forebrain are the thalamus and hypothalamus. The thalamus functions as a sensory relay station in the brain. The hypothalamus helps maintain homeostatis, it is also the point where the nervous system intersects with the endocrine system.
Re:
This is a nice summary of the basic structures of the brain found within your text book. Including information from the video would also add to your response. Also your text referred to Phineas Gage and the effect of his accident would have been an interesting incorporation into your response on the structures of the brain.
Re:
I will try to incorporate the videos and examples in my answers from now on.
