Cerebral Cortex Structures and Functions

This pre-lab video for neuroscience Lab 4 covers the gyri and sulci of the cerebral cortex. It begins with an overview of the cerebral cortex's divisions and then delves into the anatomy of the frontal, parietal, and temporal lobes, as well as the insula. The video also examines the medial and inferior surfaces of the cerebrum, highlighting key structures and their functions.

What is the primary function of the gyri in the cerebral cortex?

• To divide the brain into hemispheres

• To increase the surface area for neural connections

• To separate the lobes of the brain

• To protect the brain from injury

Which sulcus divides the frontal and parietal lobes?

• Calcarine sulcus

• Lateral sulcus

• Central sulcus

• Parietal-occipital sulcus

What is the role of the precentral gyrus in the frontal lobe?

• Visual processing

• Motor control

• Auditory processing

• Sensory processing

Which gyrus is located just posterior to the central sulcus in the parietal lobe?

• Postcentral gyrus

• Precentral gyrus

• Superior temporal gyrus

• Inferior frontal gyrus

What divides the superior and inferior parietal lobules?

• Calcarine sulcus

• Lateral sulcus

• Intraparietal sulcus

• Central sulcus

Which structure is found deep within the lateral sulcus?

• Parahippocampal gyrus

• Cingulate gyrus

• Insula

• Lingual gyrus

What is the function of the cingulate gyrus?

• Motor control

• Emotional processing

• Visual processing

• Auditory processing

Which gyrus is located superior to the corpus callosum?

• Uncus

• Parahippocampal gyrus

• Lingual gyrus

• Cingulate gyrus

What separates the parahippocampal gyrus from the lingual gyrus?

• Calcarine sulcus

• Lateral sulcus

• Central sulcus

• Collateral sulcus

Which gyrus is the most medial on the inferior surface of the cerebrum?

• Gyrus rectus

• Orbital gyrus

• Uncus

• Cuneus
