What is the action of dopamine on the postsynaptic membrane?
All neurotransmitters have an effect on the post synaptic membrane of either inhibition or excitation. Dopamine is an Excitatory NT so if a Excitatory Neuron meets with another Excitatory Neuron it creates Excitation. However if it meets with an Inhibitory Neuron Dopamine and the other Excitatory NT's wll only create Inhibition. Only GABA and Glycine are considered Inhhibitory NTransmitters.
What messages does GABA send to a receiving neuron?
GABA sends______messages to a recieving neuron
A neurotransmiter that allows sodium ions to leak into a postsynaptic neuron causes?
A neurotransmitter that allows sodium ions to leak into a postsynaptic neuron causes excitatory postsynaptic potentials. The neurotransmitter that is not synthesized in advance and packaged into synaptic vesicles is nitric oxide.
What determines if an action potential is initiated in the postsynaptic neuron?
Every time neurotransmitter is released from the presynaptic neuron it generates an excitatory post synaptic potential(EPSP) in the postsynaptic neuron. When the EPSP is greater than the threshold for excitation an action potential is generated.
Does a neuron become depolarized during an inhibitory postsynaptic potential?
False
What determines the effect that a neurotransmitter has on the postsynaptic neuron?
the receptors on the postsynaptic membrane

What happens when neurotransmitters communicate an excitatory message to the postsynaptic neuron?
When neurotransmitters communicate an inhibitory message to the postsynaptic neuron:
What part of the neuron sends information to others?
Presynaptic neuron sends postsynaptic receives

What is the voltage change at the receptor site of a neuron?
postsynaptic potential (PSP)
Does a neuron become depolarized during an inhibitory postsynaptic potential?
False
When cholinergic receptors are stimulated they?
sodium ions enter the postsynaptic neuron.
Neurotransmitters communicate an inhibitory message to the postsynaptic neuron?
reuptake is inhibited
Inhibitory postsynaptic potential is associated with what?
An inhibitory postsynaptic potential (IPSP) is a kind of synaptic potential that makes a postsynaptic neuron less likely to generate an action potential.
