Biology: The Lobes of the Brain

The lobes of the brain are the parts of the cerebrum.

1. Frontal lobe (front)

In the human brain, the precentral gyrus and the related costical tissue that folds into the central sulcus comprise the primary motor cortex whic controls voluntary movements of specific body parts associated with areas of the gyrus.

2. Occipital lobe (back)

The smalles of four lobes of the brain, the occipital lobe is located in the rearmost portion of the skull. The first functional area is the primary visual cortex. It contains a low-level description of the local orientation, spatial-frequency and color properties within small receptive fields. Primary visual cortex projects to the occipital areas of the ventral stream (visual area 2 and visual area 4) and the occipital areas of the dorsal stream - visual area V3, visual area MT (v5) an visual area DP.

3. Parietal lobe (top)

The parietal lobe integrates sensory information from different modalities, particularly determining spatial sense and navigation. E…
