The brain is the control centre for your body and it sits in your skull at the top of your spinal cord. The brain has three main parts. 1  The cerebellum (say se-re-bell-um). The brain stem, that controls a lot of the 'automatic' actions of your body such as breathing and heart beat, and links the brain to the spinal cord and the rest of the body.
The last part of the telencephalon is the corpus callosum, which connects the two hemispheres of the brain together. The thalamus and hypothalamus make up the rest of the forebrain. The function of the thalamus is to distribute information to the cerebrum from the spinal cord.The thalamus controls what, as well as how much, information is sent and where in the cerebrum that information is sent, as well.s far as the brain stem is concerned, the brain stem is *not* part of the forebrain. It is actually considered the hindbrain. I always remembered this because the word hind always made me think of bottom, and the brain stem is at the bottom of the brain.
