The Neurosurgeon The temporary lobe comprises every(prenominal) the tissue that lies below the Sylvian fissure and anterior to the occipital and parietal cortex. The profane regions can be divided on the asquint surface into those that are auditive (Brodmanns area) and those that form the ventral visual stream on the lateral blase lobe. The visual regions are referred to as either infero impermanent cortex or by von Bonin and Baileys designation, TE. The sulci of the temporal lobe contains most of the cortex. The superior temporal sulcus (STS) which separates the superior and center(a) temporal gyri can be divided into many sub regions. It receives input from auditory, visual, and physical 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 a reas known as TH and TF. The fusiform gyrus and home(a) temporal gyrus are part of the lateral temporal cortex. The uncus refers to the anterior propagation of the hippocampus. The hippocampus, as well as the amygdala, are buried deep in spite of appearance 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 committed to the archicortex. Studies have demonstrated four projection pathways of information in the temporal lobe which individually form separate chromosome mappings. First, auditory and visual information processes from the primary regions finishing 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 stim ulus 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 terminal 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.

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 temporal sulcus (S TS) 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 four 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.
