Question
What causes synaptic facilitation o Release of greater than usual number of synaptic vesicles Activation of synaptotagmin by means of phosphorylation O Release of symaptic vesicles loaded with extra neurotransmitter QUEBTION 2 Which process differentiates long-term firom shout-term sensitization? O Changes in the symapses between the sensory and motor neurons o Synaptic transmission hetween the facilitatory and sensory neurons Changes in gene expression O Production of cAMP QUEBTION 3 Which property of LIP underlies Pavlovian conditioning Associativity O Requirement for coincident activation of pre- and postsynaptic neurons O Complementanity o Specificity of input Which conditionls)must be met to induce LIP OGlutamate must be released from the presynaptic terminal Glutamate must open the postsymaptic AMPA recepors O The postsynaptic membrane must be depolarined for a period of time Mblock must be expelled from NMDA recepsors to alkw a influx O All of the above Which observation would demonestrate the spike timing-dependent plasticity of synapses? o Whothor ar not LTP occurs is dapandant on the spociic tamporal patom af action potentais O Switching the relative timing of action potential and EPSP by as little as 20 ms can switch the response from LT13 to LIP, or vice-versa. O LIP occurs whenever an action potential precedes an EPSP LTD occurs whenever an action podential folloas an EPSpExplanation / Answer
1)c the cause of synaptic facilitation is buildup of calcium in presynaptic vesicles
2) change in gene expression
3)Associativity
4)All the above
3)
