Forebrain:
cerebrum
cortex
hypothalamus
thalamus
pituitary gland
The _____________ is largest part of brain which receives
sensory input, integrates info, commands voluntary motor responses,
works with other brain parts, and is site of consciousness
Cerebral ____________is the thin highly folded
outer gray matter that covers cerebral hemispheres and is
responsible for sensation, voluntary movement, all thought,
consciousness
The __________________ is integration center that helps
with homeostasis by regulating hunger, sleep, thirst, water, body
temperature, and water balance. It controls the
pituitary gland thus serves as link between nervous and endocrine
system.
The __________receives most sensory input, integrates info, and
sends it to right place in cerebrum
The ___________ _________ , an important endocrine gland,
extends down from the hypothalamus and is controlled by the
hypothalamus.
Midbrain - relay station for tracts between cerebrum and
spinal cord or cerebellum
Hindbrain:
cerebellum
pons medulla
oblongata
The ___________________ maintains posture and balance;
coordinates voluntary muscle movements; and is Involved in learning
of motor skills (ex; playing baseball, playing piano)
The _________ is bridge from cerebellum to rest of CNS
The _____________ ______________ is important for involuntary
activities: heartbeat, breathing, blood pressure, digesting,
… some reflex centers.
42.3 Cellular Basis of Learning and Memory
Define the terms learning and
memory, and describe their relationship to one
another.
____________ is the process by which
new information is acquired.
_____________ is the ability to store
and retrieve information derived from experience and is essential
for learning. Memory may be short – or long-
term. Memories may be factual or skills
3 factors that help transfer
information from short term to long term memory
Repetition or rehearsal
Association with emotions
Association of new data with data previously learned
and stored
What study skills can enhance this
transfer of information to long-term memory?

Discuss how memory is related to changes in the strength
of connections.
Hippocampus of the limbic system is a key
region of the brain involved with learning and memory.
Long-term potentiation (LTP) is the
long-lasting strengthening of connections between neurons.
Multiple stimuli caused neurons to communicate
more readily, responses were stronger and longer.
Long-term memory involves activation of genes
in the presynaptic cell and ultimately protein synthesis.
These proteins lead to addition of more connections at
synapses. Such a change in strength of the connection between
2 neurons, which occurs as a result of learning, is termed
synaptic plasticity.
What part of the limbic system is a key brain region involved
with learning and memory? ____________
What is the long-lasting strengthening of connections between
neurons?________________
______________________
What causes neurons to communicate better with stronger
and longer lasting responses? _____________________________
Synaptic plasticity is a change in strength of the connection
between 2 what? ___________
