What are the five lobes of the cerebrum?
- Frontal
- Insula
- Parietal
- Occipital
- Temporal Lobe

Cerebral hemispheres
Sulci
Fissures & grooves in the cerebral cortex
Gyri
Folds in the cerebral cortex (the high points?)
Longitudinal Fissure
divides the right and left hemispheres of the cerebrum

central sulcus
- separates frontal and parietal lobe
- separates the motor and sensory regions of the brain
- look for the continuous sulcus.

precentral gyrus
primary motor cortex. Generates voluntary commands to the skeletal muscles
postcentral gyrus
primary sensory cortex
where the general sense of touch is perceived. Other senses more complex & require much more cortex
lateral sulcus
boundary between frontal and temporal lobe

Insula
is a portion of the cerebral cortex folded deep within the lateral sulcus
corpus callosum
thick white matter that connects the cerebral hemispheres.
(Side note: The inferior portion is the fornix. Connects deep structures of the limbic system. Narrows anteriorly to connect with anterior commissure)

septum pellucidum
anterior commissure
another tract of white matter connecting the left and right cerebral hemispheres
