Long term potentiation describes
The strengthening of neural connections via repeated stimulation
How long term memories are formed
The day to day function of the hippocampus
How short term memories may be processed into long term memories
Which of the following may play a role in the synaptic strengthening noted in long term potentiation?
An increased release of glutamate from the axon terminal
An increase in the sensitivity of post synaptic receptors
The creation of new synapses
All of the above
Where are memories most likely stored?
in a synapse
in glutamate
in a presynaptic neuron
in a postsynaptic neuron
Neurohormones
are manufactured during synaptic plasticity.
are manufactured by the endocrine system.
communicate messages to dendrites.
communicate messages slower than neurotransmitters.
When learning and memory occur
neurons change in structure and function.
there is an increase in the amount of synapses produced by neurons, thereby enabling them to flow more freely within a neural pathway.
new neurotransmitters grow and interconnect the neurons to form a pathway for the information.
neurons assemble in a formation that creates a neural pathway for the learning and its subsequent memory.
Long-term potentiation and long-term depression are _____ dependent processes.
time
activity
learning
learning and memory
If long-term potentiation is to occur between two neurons, then
the two neurons must be activated simultaneously
the two neurons must be connected within a neural
pathway.
the existing connection between the two neurons must be weak.
the existing connection between the two neurons must be strong.
During chemical communication within the brain, neurohormones and neurotransmitters are both secreted from
the hypothalamus
the pituitary gland.
synapses.
axon terminals.
Which of the following statements about learning is not true?
Learning causes changes at the synapse.
Learning can create new neural pathways.
Learning causes weakening of synaptic connections
Simultaneous firing of two adjacent neurons makes those neurons...
more inclined to fire together in the future.
less inclined to fire together in the future.
rearrange their connections.
prune connections that cannot adapt to the activity.
