List the 4 major lobes of the cerebral hemisphere and describe what each is primarily responsible for?

Answer 1

The frontal lobe, primarily asociated with personality and conscious thought. The temporal lobe which has ties with the sense of sound. The occipital lobe which is commonly accepted as the area dealing with site. The parietal lobe is largely unknown but is though to deal with spacial awareness and navigation.

If you need more, here's a bit of a further elaboration.

1. The four major lobes of the cerebral hemisphere are:

The frontal lobe: contains most of the dopamine-sensitive neurons in the cerebral cortex. The dopamine system is associated with reward, attention, long-term memory, planning, and drive. The executive functions of the frontal lobes involve the ability to recognize future consequences resulting from current actions, to choose between good and bad actions (or better and best), override and suppress unacceptable social responses, and determine similarities and differences between things or events. Therefore, it is involved in higher mental functions. The frontal lobes also play an important part in retaining longer term memories which are not task-based. These are often memories associated with emotions derived from input from the brain's limbic system. The frontal lobe modifies those emotions to generally fit socially acceptable norms. Psychological tests that measure frontal lobe function include finger tapping, Wisconsin Card Sorting Task, and measures of verbal and figural fluency.

The temporal lobe: The temporal lobe is involved in auditory perception and is home to the primary auditory cortex. It is also important for the processing of semantics in both speech and vision. The temporal lobe contains the hippocampus and plays a key role in the formation of long-term memory.

The occipital lobe: is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. This is very important; it contains the primary visual cortex.

The parietal lobe: is a lobe in the brain. It is positioned above (superior to) the occipital lobe and behind (posterior to) the frontal lobe. The parietal lobe integrates sensory information from different modalities, particularly determining spatial sense and navigation. For example, it comprises somatosensory cortex and the dorsal stream of the visual system. This enables regions of the parietal cortex to map objects perceived visually into body coordinate positions. The parietal lobe plays important roles in integrating sensory information from various parts of the body, knowledge of numbers and their relations, and in the manipulation of objects. Portions of the parietal lobe are involved with visuospatial processing. Although multisensory in nature, the posterior parietal cortex is often referred to by vision scientists as the dorsal stream of vision (as opposed to the ventral stream in the temporal lobe). This dorsal stream has been called both the 'where' stream (as in spatial vision) and the 'how' stream (as in vision for action.

P.S. I hope that helped. Thanks. =)
