draw up step-by-step representation of sequence of events during impulse conduction. Which is correct order?

a. stimulus received by soma
b. resting membrane potential changes into action potential
c. refractory period during which the impulse is generated
d. neurotransmitters allow synaptic transmission of the impulse
e. postsynaptic potentials determine whether the next neuron will produce an action potential

4

Examples of the neurotransmitters. which is NOT correct?

1. curare causes paralysis because it functions as a antagonist which suppresses the action of acetylcholine
2. high level of acetylcholine may explain deteriorating cognitive functions in Alzheimer's disease
3. Severe depression is associated with low levels of noradrenaline in the brain + manic condition is associated with very high levels
