Neurotransmitter Flashcards
Neurotransmitter
A chemical substance that carries information between neurons
Lock and key processs
The lock and key process refers to the fact that when a neurotransmitter (key) is released from a pre-synaptic neuron into the synapse it must be the rich chemical shape to successfully bind to the receptor sites (lock) on the dendrites of the postsynaptic neuron.
A specific key (neurotransmitter that is the right chemical shape) needs to be released to “unlock” the potential.
Excitatory effects and GLUTAMATE!!!
An excitatory effect occurs when excitatory transmitters bind with the receptor sites of the postsynaptic neuron. Once they are bound they INCREASE the likelihood of the postsynaptic neuron firing an action potential.
GLUTAMATE!!!!!
The primary excitatory neurotransmitter, it causes the postsynaptic neuron to become more likely to fire an action potential
Inhibitory effects and GABBA :(
An inhibitory effect occurs when inhibitory neurotransmitters bind with the receptor sites of the postsynaptic neuron, once they bind they decrease the likelihood of the postsynaptic neuron firing an action potential.
GABBA :(
The primary inhibitory neurotransmitter, it causes the postsynaptic neuron to become less likely to fire an action potential
