It may also be involved in some cognitive functions such as attention and language cingulate gyrus - a part of the brain situated in the medial aspect of the cerebral cortex receiving input from the thalamus corpus callosum - a wide, flat bundle of neural fibers beneath the cortex that connects the left and right cerebral hemispheres and facilitates interhemispheric communication fornix - a C-shaped bundle of fibers (axons) in the brain, and carries signals from the hippocampus to the hypothalamus frontal lobe - the front region of the cerebrum hippocampus - plays important roles in the consolidation of information from short-term memory to long-term memory hypothalamus - a portion of the brain that contains a number of small nuclei with a variety of functions. The most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland.

It is the location of the primary somatosensory cortex

8 Human Anatomy and Physiology, 7e by Elaine Marieb & Katja Hoehn Copyright © 2007 Pearson Education, Inc., publishing as Benjamin Cummings. precentral gyrus - prominent structure in the frontal lobe of the human brain and an important landmark. It is the location of the primary motor cortex cortex temporal lobe - region of the cerebral cortex involved in the retention of visual memories, processing sensory input, comprehending language, thalamus - relay center for both sensory and motor input to the cortex Cerebrospinal Fluid Filled Spaces: cerebral aqueduct - within the mesencephalon, this space contains cerebrospinal fluid and connects the third ventricle to the fourth ventricle fourth ventricle - CFS filled space in the brain interventricular foramen - channels that connect the paired lateral ventricles with the third ventricle at the midline of the brain lateral ventricle - CFS filled space in the brain third ventricle - CFS filled space in the brain
