The function of the Frontal lobe is:
Motor control, memory, problem solving, planning, language, judgement, social behaviour.
The function of the Parietal lobe is:
Sensory input, goal directed movement, visual input, spatial awareness, mathematics.
The function of the Occipital lobe is:
Vision, recognising words,
The function of the Temporal lobe is:

Glial cells that make the myelin sheath around neurons in the CNS are called:
Oligodendrocytes
What are astrocytes?
Most abundant glial cells in the brain.
They regulate the transmission of electrical impulses within the brain.
