Lobes
The surface of the cerebral hemispheres is folded and forms fissures
and sulci where some divide the cortex into different lobes.
Frontal lobe/ lobus frontalis
The frontal lobes are functionally dived into two major areas. The
anterior part, the prefrontal cortex, is important in higher mental
functions and in the determination of personality. The posterior
part of the frontal lobe is divided into a premotor and motorarea.
In the motor area movement is actually produced whereas the movements
are modified in the premotor area.
Temporal lobe/ lobus temporalis
The temporal lobes have numerous functions. The auditory cortex
is located on the lateral superior parts and the hippocampus form
the medial parts of the temporal lobes. The speech area is located
on the left side of the brain in right-handed individuals.
Parietal lobe / lobus parietalis
The parietal lobes are located behind the frontal lobes. Immediately
behind the central sulcus/ulcus centralis is the primary sensory
cortex that controls sensation, such as touch, pressure, and localisation
of objects that touch the skin. Behind this area is a large association
area that controls sensations as judgement of size, shape texture
and weight.
Occipital lobe/ lobus occipitalis
The occipital lobes are concerned with vision. The medial sides of
the lobes deal with primary visual reception whereas the rest of
the lobes are involved in visual recognition of shape, size and
colour.
