cerebrum ...
The cerebrum is divided into four main lobes: frontal, parietal, temporal, and occipital. There is no fifth lobe of the cerebrum.
temporal lobe
The lateral ventricles extend into the frontal, parietal, occipital, and temporal lobes of the cerebral hemispheres. The frontal horn extends into the frontal lobe, the body extends into the parietal lobe, the atrium extends into the occipital lobe, and the temporal horn extends into the temporal lobe.
The occipital lobe is located at the back of the cerebrum, behind the parietal lobe. It is primarily responsible for processing visual information.
The biggest part of the brain is the cerebrum. The cerebrum makes up 85% of the brain's weight.The cerebrum is the thinking part of the brain and it controls your voluntary muscles: the ones that move when you want them to.
The groove that divides the cerebrum in two hemispheres is called the longitudinal fissure. It separates the left and right hemispheres of the brain and is where the corpus callosum connects the two hemispheres.
The two halves of the cerebrum are the left and right hemispheres.
Occipital lobe
It is responsible for vision
The Cerebrum: The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebral cortex is divided into four sections, called "lobes": the frontal lobe, parietal lobe, occipital lobe, and temporal lobe.
