Hypothalamus - part of the diencephalon, ventral to the thalamus. The structure is involved in functions including homeostasis, emotion, thirst, hunger, circadian rhythms, and control of the autonomic nervous system. In addition, it controls the pituitary gland

Hippocampus - the portion of the cerebral hemisphers in basal medial part of the temporal lobe. This part of the brain is important for learning and memory -- for converting short term memory to more permanent memory, and for recalling spatial relationships in the world about us

Gyrencephalic - when the cerebral cortex is highly folded and convuluted (due to gyri and sulci)

Frontal Lobe - the most anterior portion of the cerebral cortex (in front of the central sulcus); it is involved in reasoning, planning, parts of speech, movement, emotions, and problem-solving

Dendrite - one of the extensions of the cell body that are reception surfaces of the neuron

Corpus Callosum - the large bundle of axons which connect the two cerebral hemispheres. It disseminates information from the cerebral cortex on one side of the brain to the same region on the other side

Cerebral Hemispheres - right and left halves of the forebrain

Cerebellum - structure located in the back of the brain (dorsal to the pons) involved in central regulation of movement, such as basic movement, balance, and posture; comes from the Latin word meaning "little brain"; is divided into two hemispheres and has a cortex

Central Sulcus - the major groove which divides the frontal lobe from the parietal lobe
