The correct statements based on the given information about the cerebral cortex is (2); the grey matter of the cerebral cortex is due to the presence of neuron cell bodies.
The other statements , and are incorrect because The cerebral cortex is responsible for a wide range of functions, including sensory perception, motor functions, memory, language, and higher-order cognitive processes.
The association areas of the cerebral cortex are involved in complex and higher-order cognitive functions, such as problem-solving, decision-making, and integrating sensory information.
The cerebral cortex is highly folded and convoluted, forming ridges (gyri) and grooves (sulci). This folding increases the surface area of the cortex, allowing for a greater number of neurons and functional areas within a limited space.
