Significant timbre-related brain activation was found in well-defined regions of posterior Heschl's gyrus . Each hemisphere has a frontal, temporal, parietal and occipital lobe. Thus, the superolateral surface of the hemisphere drains into the superior sagittal sinus while the posteroinferior aspect drains into the transverse sinus. The cerebrum or brain can be divided into pairs of frontal, temporal, parietal and occipital lobes. The cortex covers the outer portion (1.5mm to 5mm) of the cerebrum and cerebellum . We have seen that the prosencephalon is divisible into a mediandiencephalon and two lateral telencephalic vesicles (Fig. Each hemisphere is divided into four lobes: frontal, parietal, occipital, and temporal. This is inter-connected via pathways that run sub-cortically. The central sulcus runs posterior-medial to anterior-lateral and separates the frontal lobe from the parietal lobe.
