TWO HALVES OF THE BRAIN
Two halves of the brain
CEREBRUM
CEREBRUM (PALLIUM) – is the largest part of the brain.
• It occupies anterior, middle and upper part of posterior cranial fossa
• It is made-up of outer grey matter and inner white matter and basal
ganglia within the white matter
• Each hemisphere contains a cavity called lateral ventricles
EXTERNAL FEATURES:
• 1. Has three surfaces
• 2. Four borders
• 3. Three poles
• 4. Four lobes Vijaylaxmi Pattanshetti
