Question

Quizplus · Accepted Answer

The cerebral cortex contains the highest number of neurons and synapses in the brain, which are responsible for complex cognitive processes such as perception, attention, language, memory, and consciousness.

Answer: D
 The cerebral cortex fully develops during the third trimester of pregnancy, which is the final stage of prenatal development before birth. This period is critical for the formation of the brain's structure and function, and any disruptions or abnormalities during this time may have long-lasting effects on the individual's cognitive and behavioral development.

B and C are incorrect as the cerebral cortex continues to grow and is also sensitive to environmental influences.
