The Lobes of the Brain

The frontal lobe is involved in establishing priorities and planning. Richard M. Restak, in Brainscapes: An Introduction to What Neuroscience Has wise to(p) about the Structure, Function, and Abilities of the Brain (1995), writes: The frontal lobe makes up 50 percent of the volume of each cerebral hemisphere in humans. It initiates totally motor activity, including speech; its most anterior divisions, the prefrontal lobes and adjuvant motor pallium, integrate personality with emotion and transform concept into action.

The temporal lobe contains a sensory area related to hearing. nestled within each temporal lobe are the amygdala and the hippocampus, which are, writes Restak in Brainscapes, involved in learning, memory and the experience and expression of emotion. A portion of the temporal lobe, called the entorhinal cortex, channels cortical inputs to the hippocampus. Restak writes: Fibers from all 4 lobes, along with association fibers uniting these separate connections into one co-ordinated experience, converge into the hippocampal region. In Evolving Brains, Allman points out that the amygdalaâ€"so significant to emotional processingâ€"also receives input from a cortical area within the temporal lobe called the inferotemporal opthalmic cortex, which is greatly spread out in higher primates.



Allman notes that Charles Goss, Robert Desimone, Edmund Rolls, and David Perrett and their colleagues have shown that neurons in part of the inferotemporal cortex are especially sensitive to the images of faces. We will discuss ad hoc areas of the cortex involved in processing different kinds of visual stimuli later in this narrative.

The occipital lobe includes sophisticated topographical maps with mazy interconnections required for visual processing, and according to MedlinePlus Dictionary, has the form of a 3-sided pyramid. The Merck Manuals Online checkup Library states that in addition to processing and interpreting vision, cortical areas in the occipital lobe...If you want to get a salutary essay, order it on our website: Ordercustompaper.com
