Lobes and Sulci of the Cerebral Cortex

00:01 Welcome to this presentation on the cerebral cortex. Our first stop here is to identify the four lobes that are associated with the cerebral cortex. Here, we have a lateral view of the four lobes and they’re in different colors. First, we see in blue, we see the frontal lobe.

00:30 Located posterior to the frontal lobe and highlighted is the parietal lobe. Then we see the occipital lobe highlighted in the right, red color on the posterior aspect of the cerebral cortex.

00:52 Then lastly in light green, the temporal lobe is identified. Stayed on the lateral aspect, next, we should identify three major sulci or sulci. The first is the central sulcus. This will separate the frontal lobe here from the parietal lobe over here to the right of the central sulcus.

01:24 The next sulcus is the one that will separate the parietal lobe from the occipital lobe and the occipital lobe from the temporal lobe here inferiorly. This is the parieto-occipital sulcus.

01:42 Then the third and final major one is the lateral sulcus which more precisely is a lateral fissure This will separate your temporal lobe from the frontal lobe here anteriorly.

01:59 It will also separate the temporal lobe from the parietal lobe here more posteriorly.
