The neurosurgeon The laic lobe comprises all the tissue that lies downstairs the Sylvian fissure and anterior to the occipital and parietal pallium. The lay regions can be divided on the askance surface into those that argon audile (Brodmanns study) and those that form the adaxial visual stream on the squint impermanent lobe. The visual regions are referred to as either infero secular cortex or by von Bonin and Baileys designation, TE. The sulci of the temporal lobe contains to the highest degree of the cortex. The superior temporal sulcus (STS) which pick outs the superior and halfway temporal gyri can be divided into some sub regions. It receives gossip from auditory, visual, and corporate regions as swell as the frontal and parietal regions and the paralimbic cortex. The average temporal region includes the genus Hippocampus (and surrounding cortex) and the pointed gyrus. The posterior shoemakers last of the temporal lobe is referred to as the par ahippocampal cortex and includes areas known as TH and TF. The fusiform gyrus and interior temporal gyrus are part of the lateral temporal cortex. The uncus refers to the anterior continuation of the hippocampus. The hippocampus, as well as the amygdala, are buried deep inwardly the temporal lobe. The temporal lobes have many internal connections which project to the stunning systems, to the parietal and frontal regions, to the limbic system, and to the humble ganglia. The neocortex of the left and well(p) lobes is connected to the archicortex. Studies have demonstrated quadruplet projection pathways of nurture in the temporal lobe which each form separate posts. First, auditory and visual information processes from the primary regions ending in the temporal pole form the ventral stream of visual processing. Its function is design to be stimulus recognition. Second, auditory, visual, and somatic project into the superior temporal sulcus whose function is stimulus categorization. Third, auditory and visual information is projected to the medial temporal regions including the hippocampus (called the preforant pathway) and the amygdale. This pathway is of the essence(p) to long term memory. Fourth auditory and visual information goes to the area of the frontal lobe which is necessary for various aspects of movement, control, defraud term memory, and affect.

The temporal regions can be divided on the lateral surface into those that are auditory (Brodmanns area) and those that form the ventral visual stream on the lateral temporal lobe. The visual regions are referred to as either inferotemporal cortex or by von Bonin and Baileys designation, TE. The sulci of the temporal lobe contains most of the cortex. The superior tempor al sulcus (STS) which separates the superior and middle temporal gyri can be divided into many sub regions. It receives input from auditory, visual, and somatic regions as well as the frontal and parietal regions and the paralimbic cortex. The medial temporal region includes the hippocampus (and surrounding cortex) and the fusiform gyrus. The posterior end of the temporal lobe is referred to as the parahippocampal cortex and includes areas known as TH and TF. The fusiform gyrus and interior temporal gyrus are part of the lateral temporal cortex. The uncus refers to the anterior extension of the hippocampus. The hippocampus, as well as the amygdala, are buried deep within the temporal lobe. The temporal lobes have many internal connections which project to the sensory systems, to the parietal and frontal regions, to the limbic system, and to the basal ganglia. The neocortex of the left and right lobes is connected to the archicortex. Studies have demonstrated fou r projection pathways of information in the temporal lobe which each form separate functions. First, auditory and visual information processes from the primary regions ending in the temporal pole form the ventral stream of visual processing. Its function is thought to be stimulus recognition. Second, auditory, visual, and somatic project into the superior temporal sulcus whose function is stimulus categorization. Third, auditory and visual information is projected to the medial temporal regions including the hippocampus (called the preforant pathway) and the amygdale. This pathway is crucial to long term memory. Fourth auditory and visual information goes to the area of the frontal lobe which is necessary for various aspects of movement, control, short term memory, and affect.
