Behavioral Neuroscience, Lecture on September 17th
Major Divisions of the Brain
Telencephalon (cerebral hemisphere) forebrain
higher order functions take place.
gyri (hill) and sulci (valley) - ridges and valley's on the brain.
o really deep sulci are called fissures.
o one major fissure called the longitudinal fissure divides the brain
into two hemispheres.
two subsystems, basal ganglia - important for movement and motor
control and the limbic system - important for emotions and memory
Diencephalon (thalamus and hypothalamus) forebrain
thalamus serves as a sensory relay, incoming sensory information
synapses here then sent on to the cerebrum.
hypothalamus helps to maintain homeostasis, controls the endocrine
system (hunger, thirst and reproduction).
Mesencephalon (midbrain) midbrain
top of the brainstem.
midbrain has both sensory and motor divisions.
important for motor control.
receives sensory signals for vision.
heavily affected by Parkinson's.
