Contrast the postsynaptic mechanism of excitatory and inhibtory synapses |
Step by step
Solved in 2 steps
- Assume presynaptic excitatory neuron A terminates on a postsynaptic cell near the axon hillock and presynaptic excitatory neuron B terminates on the same postsynaptic cell on a dendrite located on the side of the cell body opposite the axon hillock. Explain why rapid firing of presynaptic neuron A could bring the postsynaptic neuron to threshold through temporal summation, thus initiating an action potential, whereas firing of presynaptic neuron B at the same frequency and the same magnitude of EPSPs may not bring the postsynaptic neuron to threshold.What is a synapse? Explain the difference between an excitatory and an inhibitory synapse.Contrast the postsynaptic mechanisms of excitatory and inhibitory synapses.
- Contrast the postsynaptic mechanisms of excitatory and inhibitory synapses. give the idea behind and contrast the twoExplain the Contrast between postsynaptic mechanisms of excitatory and inhibitory synapses?Explain the mechanism by which action potentials are prevented from being propagated to a postsynaptic cell if transmitted across an inhibitory synapse.
- Explain why synapses are preferable to direct physical connections between neurons.The correlation between neurons can explain the basis of the synaptic modification, that is, how much they can connect to each other or if they are not synchronized, how much they can lose or weaken their connections. Draw a picture of an excitatory synapse such as glutamatergic with its receptors between the pre- and postsynaptic neuron.Describe the components of the various types of synapses
