Cerebrum & Hemisphere Specialization

What structures make up the telencephalon?

• Cerebrum
• Hippocampus
• Basal ganglia
• Amygdala

What is the largest division of the human brain?

• Telencephalon

What are the two cerebral hemispheres connected by?

• Corpus callosum
• White matter structure

What is gray matter in the cerebrum?

• Outer surface of the cerebrum
• Contains neuronal cell bodies

What is white matter in the cerebrum?

• Located internally
• Contains nerve fibers/axons

What is the function of sulci and fissures?

• Demarcate specific lobes/regions of the brain

What does the interhemispheric fissure separate?

• Left cerebral hemisphere
• Right cerebral hemisphere

What does the Sylvian fissure separate?

• Anterior: temporal and frontal lobes

• Posterior: temporal and parietal lobes

What does the central sulcus separate?

• Frontal lobe
• Parietal lobe

What does the parieto-occipital sulcus separate?

• Parietal lobe
• Occipital lobe

What does the calcarine sulcus divide?

• Occipital lobe
• Superior and inferior halves

What functions are associated with the left hemisphere?

• Language
• Sequencing movements
• Understanding language
• Written and spoken language
• Analytical/logical processing
• Mathematical calculations
• Organized and sequential processing

What functions are associated with the right hemisphere?

• Nonverbal processing
• Holistic processing
• Artistic abilities
• Spatial relationships
• Hand-eye coordination
• Kinesthetic awareness
• Music
• Nonverbal communication
• Body-image awareness

What is the easiest way to differentiate hemisphere specialization?

• Left = language, logic, sequencing

• Right = spatial, nonverbal, holistic
