Telencephalon (gyri and sulci) Anatomy

precentral gyrus

precentral gyrus

premotor area

supplementary motor area and premotor cortex

superior frontal sulcus

superior frontal gyrus

the frontal lobe gyrus that runs horizontally along the top of the lobe

middle frontal gyrus

the frontal lobe gyrus that is located between the superior and inferior frontal gyri

inferior frontal gyrus (cognitive and speech function)

the frontal lobe gyrus that is located just inferior to the middle frontal gyrus

opercularis (blue), triangularis (red), orbitalis (green)

association areas

areas of the cerebral cortex that are not involved in primary motor or sensory functions; rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking

cingulate gyrus

cingulate sulcus

cingulate cortex function

When outcome doesn't match expectation the dorsal anterior cingulate cortex within cingulate gyrus sends an error cortex which is sent to precentral cortices to make a plan of action

parts of corpus callosum

intraparietal sulcus

supramarginal gyrus

angular gyrus

translates writing into speech

postcentral gyrus

occipital gyri

calcarine fissue

Cuneus (above the fissure)
Lingual gyrus (below the fissure)
both have striate cortex

lingual gyrus

cuneus

temporal lobe sulci and gyri

Superior and Inferior Temporal Sulci separate 3 gyri:

•Superior Temporal Gyrus
•Middle Temporal Gyrus
•Inferior Temporal Gyrus


ALSO
hippocampal fissure
uncas
parahippocampal gyrus
rhinal sulcus

superior temporal gyrus

middle temporal gyrus

inferior temporal gyrus

superior temporal sulci

inferior temporal sulci
extends from lower temporal lobe surface to occipital lobe

uncus

rhinal fissure function

It is the primary way of sending info to hippocampus

hippocampal fissure

a fissure that extends from the brain's corpus callosum to the tip of the temporal lobe.

parahippocampal gyrus

a fold of tissue near the hippocampus that is often included in the limbic system
