Neuron & Brain Structure — NEET Biology

Which of the following statements regarding the human cerebral hemispheres and cortex are correct? S1: The cerebrum forms the major part of the human brain, divided longitudinally into two cerebral hemispheres connected by the corpus callosum. S2: The cerebral cortex is called the grey matter due to a high concentration of myelinated nerve fibres. S3: Association areas within the cerebral cortex are crucial for complex functions such as intersensory associations, memory, and communication. S4: The inner part of the cerebral hemisphere consists of fibres of tracts covered with myelin sheath, referred to as white matter. S5: The cerebrum primarily wraps around the hypothalamus, which serves as a major coordinating centre for sensory and motor signaling.
