Q

Excitatory neurotransmitter

A

-When the excitatory neurotransmitter binds to the post synaptic receptors, the post synaptic cell becomes positively charged
-This makes it more likely the post synaptic cell will fire so an impulse will travel down its axon
-Increases brain activity in the CNS

Q

Inhibitory neurotransmitter

A

-When the inhibitory neurotransmitter binds to the post synaptic receptors the post synaptic cell becomes negatively charged
-This reduces the likelihood that the post synaptic cell will fire
-This decreases brain activity in the CNS

Q

Summation

A

-When the excitatory and inhibitory influences are added together
-If the overall effect is mainly inhibitory/negatively charged this reduces the likelihood the neuron will fire an impulse down the post synaptic neuron
-If it is mainly excitatory/ positively charged the impulse will fire an impulse down the post synaptic neuron
