Term
Does a neuromuscular junction have a high or low safety factor? What about central neurons? |
|
Definition
NMJ - high safety factor
Central neuron - low safety factor |
|
|
Term
What types of synapses are usually excitatory? inhibitory? |
|
Definition
Excitatory - axodendritic
Inhibitory - axosomatic |
|
|
Term
Where are metabotropic synapses usually found? What is their purpose? |
|
Definition
They are typically found at modulatory axoaxonic synapses
They gate ion channels indirectly |
|
|
Term
What are the two types of Glutamate gated receptors in the brain? |
|
Definition
NMDA receptors and non-NMDA (AMPA and kainate) receptors |
|
|
Term
Non-NMDA receptors are the major postsynaptic players in what type of response? |
|
Definition
Excitatory post-synaptic potential (EPSP) |
|
|
Term
With regards to permeability, how do NMDA and non-NMDA receptors differ? |
|
Definition
NMDA receptor channels are permeable to Ca2+ |
|
|
Term
NMDA receptors are blocked by what? |
|
Definition
|
|
Term
NMDA receptors play a direct role in what types of cognitive functioning? |
|
Definition
Associative learning and memory installment and consolidation |
|
|
Term
How is the Mg2+ removed in NMDA receptors? |
|
Definition
If the rate of stimulation is high, Mg2+ block is relieved by a greater depolarization of the postsynaptic membrane potential and calcium enters the postsynaptic neuron through the NMDA receptors |
|
|
Term
IPSPs result from the activation of postsynaptic receptors that cause an increase in conductance to which ions? |
|
Definition
|
|
