Your brain has the ability to change in response to
experience. This ability is known as
flexibility
plasticity
responsiveness
reactivity
Which of the following statements concerning plasticity in the brain is FALSE?
Damage to one area of brain tissue may result in changes in other areas of the brain that compensate for the damage
Experience can change the features of brain structures
Older brains show more plasticity than younger brains
Even adult brains are able to form additional neural connections
White matter is
myelinated
unmyelinated
When neural connections are repeatedly used, then it is likely that they will
strengthen
weaken
be pruned
become tired
A synapse is
a neural connection
a type of neurotransmitter
the place where neurons communicate
the part of the neuron where small extensions grow
The process of eliminating synaptic connections is called
synaptic pruning
dendritic sprouting
adaptive plasticity
dendritic growth
Learning can best be described as?
A permanent change as a result of experience to an individual's behaviour.
Small changes that occur on both the pre- and post-synaptic neurons.
A relatively permanent change in behaviour due to experience
What happens in Ms Foley's Psychology class all the time
Which changes occur on the post-synaptic neuron when learning has taken place?
Greater number of neurotransmitters produced and released
Bushier dendrites
Additional neurons become involved in sending neurotransmitters across the synapse
Increased sensitivity of receptor sites on dendrites
Hebb's rule suggests .....
Cells that fire together, wire together
Neurons are better when they hang out together
Action potential equals ion differential
It takes two to tango
Which statement about LTP is not true?
LTP leads to increased efficiency of communication
LTP occurs due to high frequency use
LTP involves 2 or more neurons
LTP removes any unused synaptic connections
Which is most important for learning and memory
LTP
LTD
LIT
Both LTP and LTD
Which of the following occur with LTP
enables postsynaptic neurons to be more easily activated
post synaptic neurons are more responsive to presynaptic neuron
increased efficiency in transferring information along the pathway
decreases the likelihood that what is learned will be forgotten
unused synapses are eliminated
Which of the following are similarities between LTP and LTD?
both involve glutamate
both are long-lasting effects
both are activity dependent
both rely on the idea that "Neurons that fire apart wire apart"
both involve enhanced synaptic transmission between neurons
Memory consolidation is a ________________ process
biological
psychological
