Cerebral lobes

The cerebral cortex within each cerebral hemisphere can be divided into four main parts known as cerebral lobes. These lobes are the frontal lobe, parietal lobe, temporal lobe, and occipital lobe. The frontal lobe, located at the front, plays a major role in controlling our motor functions and executive functions, such as judgement, problem-solving, planning, behavior, personality, speech, and intelligence. The occipital lobe, found at the back, is mainly responsible for interpreting visual information. The parietal lobe is mainly devoted to perceiving general somatic sensations, sensory speech, and visuospatial orientation. Lastly, the temporal lobe serves various functions, including taste, hearing, and sensory perception. You can find more details about each lobe by clicking on the highlighted links provided in the text.

In addition to these lobes, there is another functional lobe in the brain called the limbic lobe. This lobe is associated with the emotional processing of input from sensory systems. It includes various parts of the frontal, parietal, and temporal cortices, which are arranged in an arc-like fashion on the medial and/or inferomedial surface of the cerebral hemisphere. Some of the cortical structures within the limbic lobe include the cingulate gyrus and parahippocampal gyrus.

The boundaries between the cerebral lobes are marked by certain grooves/sulci known as interlobar sulci. For example, the central sulcus separates the frontal lobe at the front from the parietal lobe at the back. The lateral sulcus separates the temporal lobe below from the frontal and parietal lobes above. The parieto-occipital sulcus, which is most noticeable on the inner surface of the brain, separates the occipital lobe at the back from the parietal lobe at the front.
