|
What do excitatory neurotransmitters increase the likelihood of and how |
The neuron firing, by producing an excitatory signal |
|
|
What happens if an excitatory neurotransmitter binds with a post-synaptic receptor and what does this cause |
It causes an electrical change in the membrane which causes an excitatory post-synaptic potential (EPSP) |
|
|
What do inhibitory neurotransmitters decrease the likelihood of and how |
A neuron firing, by filtering out excitatory signals |
|
|
What happens if an inhibitory neurotransmitter binds with a post-synaptic receptor and what does this cause |
Causes a different electrical charge in the membrane causing an inhibitory post-synaptic potential (IPSP) |
|
|
What can a post-synaptic neuron receive at the same time |
EPSP’s and IPSP’s |
|
|
What is the likelihood of a neuron firing determined by and what is this known as |
Adding up the EPSP’s with the IPSP’s, summation |
|
|
What is spatial summation |
Where a large number of EPSP’s are generated at lots of different synapses on the same post-synaptic neuron at the same time |
|
|
What is temporal summation |
Where a large number of EPSP’s are generated at the same synapse by the series of high frequency action potentials on the pre-synaptic neuron |
