Final answer:
The neocortex accounts for about 80% of the human brain's cortex. It is critical for functions such as language and consciousness and is significantly larger in humans compared to other mammals, contributing to our superior cognitive abilities.
Step-by-step explanation:
The percentage of the human brain's cortex attributed to the neocortex is a significant majority.
When asked 'What percentage of the human brain's cortex is attributed to the neocortex?', the correct answer is d) 80%.
The neocortex is a part of the brain that is involved with higher functions like language, consciousness, and sensory perception.
The neocortex makes up approximately 76% of the brain's mass, illustrating its substantial role in the brain's functioning.
Among mammals, humans have an especially large neocortex, which has many folds increasing the surface area and thereby contributing to our complex cognitive abilities.
By comparison, in other mammals, such as rats, the neocortex is relatively smoother and less expansive.
In terms of the brain's anatomy, it includes the cerebral cortex which consists of the frontal, parietal, temporal, and occipital lobes.
The cerebral cortex is protected by three layers of meninges: the dura, arachnoid, and pia maters.
Furthermore, the frontal lobes, which are a key component of the cerebral cortex, do not become fully developed until around 25 years old.
