What are the four main components of the forebain?

The forebrain consists of four main components: the cerebral cortex, which is responsible for higher cognitive functions; the corpus callosum, which connects the two hemispheres of the brain; the thalamus, which acts as a relay station for sensory information; and the hypothalamus, which regulates vital bodily functions such as temperature, hunger, and hormonal activity. Together, these components play crucial roles in processing sensory information, regulating homeostasis, and facilitating complex behaviors and thought processes.
