Summary
The folded outer layer of the cerebrum responsible for perception, language and reasoning.
In depth
About 2 to 4 mm thick, six layers, folded into gyri and sulci to increase area to about 2,500 cm². Motor and sensory homunculus maps show body representation; association areas integrate information.
Cortical layers contain different neuron types. Primary areas receive sensory input; association areas combine it. The prefrontal cortex matures last, around age 25.
Key idea: the human cortex is greatly expanded relative to other animals.
Frequently asked questions
What is Cerebral Cortex?
The folded outer layer of the cerebrum responsible for perception, language and reasoning.
Which area of biology covers Cerebral Cortex, and how advanced is it?
Cerebral Cortex is one of the 54 topics in Neuroscience. It is rated Beginner, so it suits learners who are starting out in biology. Related topics in this area include Neuron, Nervous System, Sensory and Motor Neurons.
Can you give an example of Cerebral Cortex?
The prefrontal cortex supports decision-making and impulse control.
What should I learn before Cerebral Cortex?
Cerebral Cortex is a Beginner topic, so no earlier topic is required. Other Beginner topics in Neuroscience that pair well with it include Nervous System, Neuron, Central and Peripheral Nervous Systems.
What topics are related to Cerebral Cortex?
The closest topics to Cerebral Cortex are Neuron, Nervous System, Sensory and Motor Neurons, Pain Pathways. Comparing them side by side is a good way to see how the ideas connect.
How can I check that I understand Cerebral Cortex?
Read the summary and the in-depth section, then use the quick check on the interactive lesson for Cerebral Cortex. To practise the whole of Neuroscience, use the Neuroscience quiz.
How is Cerebral Cortex different from Neuron?
Cerebral Cortex: The folded outer layer of the cerebrum responsible for perception, language and reasoning. Neuron: A nerve cell with dendrites, a cell body and an axon that transmits electrical signals. Read both side by side and note what each one explains.
How should I study Cerebral Cortex step by step?
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Neuron and explain the difference aloud. Finally, take the Neuroscience quiz and come back to this page for any question you miss.
