Brain mapping

5 Major “sections” of the human brain

Telencephalon

Diencephalon

Myelencephalon

Metencephalon

Mesencephalon

Telencephalon

L&R Hemisphere

4 lobes(8 total)

Cerebrum

Directs: Motor(voluntary), Sensory, Learning and Memory, Language and Communication

Brain Tissue

Sulci- a groove,

crevice or furrow in

medicine

-Gyri-is a ridge on the

cerebral cortex

Gyri

is a ridge on the cerebral cortex

Cerebral Cortex

Highest on intellectual function

-Neocortex (new)

-Sensory perception, motor, reasoning, thought,

language

Corpus Callosum

Band of fibers which connect L and R hemispheres of the brain

-Information Highway

allowing connectivism.

Occipital Lobe

The visual processing center

-Visual cortex

-The primary visual cortex is Brodmann area

Temporal Lobe

The temporal lobe is involved in auditory perception

 Important for the processing of semantics in speech (meaning of….)

 Contains the hippocampus and plays a key role in the formation of long-term memory

 Emotion regulation

Frontal Lobe

Dopamine-sensitive neurons in the cerebral cortex

 Socially accepted emotions

 Non task LTM’s

 Future executive decision-making, problem solving, planning, and speech.

 Three main divisions of the frontal lobes

 prefrontal cortex

 premotor area

 motor area
