The Cerebrum

Cerebrum

The largest part of the brain, containing the cerebral cortex and part of the forebrain

Cerebral Cortex

The highly folded outer layer of the cerebrum

Forebrain

A major division of the brain that includes the cerebrum

Central Sulcus

A sulcus that extends from the superior surface down the lateral surface, separating the frontal and parietal lobes

Lateral Sulcus

A sulcus located inferior to the central sulcus, separating the temporal lobe from the frontal and parietal lobes

Precentral Gyrus

The gyrus located immediately anterior to the central sulcus, containing the primary motor cortex

Postcentral Gyrus

The gyrus located immediately posterior to the central sulcus, containing the primary somatosensory cortex

Superior Temporal Gyrus

One of the three gyri in the temporal lobe, containing the primary auditory cortex

Calcarine Sulcus

A sulcus on the medial surface of the brain, associated with the primary visual cortex

Parieto-occipital Sulcus

A sulcus that forms the boundary between the parietal and occipital lobes

Cingulate Gyrus

A gyrus running around the corpus callosum, important in the limbic system and learning mechanisms

Corpus Callosum

A large bundle of nerve fibers connecting the two hemispheres of the brain

Longitudinal Fissure

A deep cleft that separates the two hemispheres of the brain

Frontal Lobe

The most anterior lobe of the cerebrum, associated with decision-making and high cognitive function

Parietal Lobe

Located posterior to the frontal lobe, associated with somatosensation and integrative processing

Occipital Lobe

The most posterior lobe of the cerebrum, concerned with vision

Temporal Lobe

Located inferior to the lateral sulcus, associated with learning, memory, auditory processing, and language

Tentorium Cerebelli

A double fold of dura mater that separates the cerebellum from the cerebrum

Pre-occipital Notch

An anatomical landmark used to define the extent of the occipital lobe

Primary Motor Cortex

The area of the brain responsible for initiating voluntary movements

Primary Somatosensory Cortex

The area of the brain that receives sensory information from the body

Primary Auditory Cortex

The area of the brain that processes auditory information

Primary Visual Cortex

The area of the brain that processes visual information

Limbic System

A complex system of structures involved in emotion, motivation, and memory
