FOREBRAIN

Thalamus • Receives, processes

and transfersinformation

Corpus callosum • Bridges the

two cerebralhemispheres

Cerebrum • Coordinates language • Controls decision

making • Produces conscious

thought

HINDBRAIN

Cerebellum • Controls basic

and skilledmovements

Medulla oblongata • Controls automatic

functions ofinternal organs

Pons • Connects cerebellum, spinal cord

with higher brain centers • Aids medulla in regulating
