What is the cerebrum and what are its main parts?

The cerebrum is the largest part of the brain, composed of two hemispheres. Each hemisphere has a cerebral cortex (grey matter surface), a core of white matter, and contains deep structures like the basal ganglia.

What are the four main lobes of the cerebrum and their functions?

The four lobes on the superolateral surface are: Frontal lobe (motor function, emotion, self-awareness), Parietal lobe (sensory information processing), Occipital lobe (visual input reception), and Temporal lobe (smell, hearing, and memory).

What are the basal ganglia and what do they do?

The basal ganglia are subcortical grey matter masses within the cerebral white matter. They include structures like the corpus striatum and are part of the extrapyramidal system, influencing the quality of motor control.

What is the insula and the limbic lobe?

The insula is a deep lobe within the lateral sulcus, sometimes called the 5th lobe. The limbic lobe is a border region associated with survival instincts like feeding, reproduction, and memory.

How are the two cerebral hemispheres connected?

The hemispheres are partly separated by the longitudinal cerebral fissure but connected by the corpus callosum. This structure links corresponding cortical areas across the hemispheres.
