|
(memory and learning)
intelligence |
the ability to learn, retain and process knowledge
|
|
|
(types of memory)
short term |
short duration, mostly electrical in functions. neurons connected in a circuit and continue to stimulate each other.
|
|
|
(types of memory)
long term |
long duration, structural in function. new synapses are formed allowing memory.
|
|
|
Basal nuclei (ganglia)
|
masses of gray matter located deep w/in hemispheres.
F(x)-relay messages from cortex to brain stem+cord, produce the NT dopamine. |
|
|
Parkinson's disease
|
is a decline in dopamine due to death of basal nuclei cells. causes tremors then paralysis. cause believed to be chemical and traumatic damage to brain. ex..designer drugs, boxing
|
|
|
The Diencephalon
|
surrounds third ventricle: almost all gray matter
|
|
|
(regions of the diencephalon)
thalamus |
f(x)-recieves, filters, +directs all afferent sensory impulses to correct region of cortex.

f(x)-suspends pituitary gland
|
|
|
(regions of the diencephalon)
hypophysis(pituitary gland) |
F(x)-hormone production
|
|
|

f(x)-connects 3rd and 4th ventricle
|
|
|
(Regions of the Braind Stem)

|
|
|
(Regions of the Braind Stem)
corpora quadrigemina |
f(x)-relay centers for visual and hearing reflexes
|
|
|
(Regions of the Braind Stem)
red nucleus |
f(X)-provides reflexes to maintain posture works w/cerebellum
|
|
|
(Regions of the Braind Stem)

f(x)-fibers relay impulses from cord to cerebrum
|
|
|
(Regions of the Braind Stem)

|
reticular formation
|
network of fibers(axons) and gray matter(throughout brain stem)
|
|
|
what happens if you damage the reticular formation?
|
causes a coma or persistent vegetative state if damaged.
|
|
|
what causes insomnia?
|
intense cerebral activity stimulates the reticular formation causing____
|
|
