Neurotransmission Simulation

An interactive animation shows neuron 1 in one molecule transmitting a signal to neuron 2 in a second molecule.

This simulation shows one neuron relaying information to another neuron. If a signaling molecule binds to neuron 1, how does the release of dopamine from neuron 2 change? Select one of the four cases to see how a signaling molecule changes neurotransmitter release.

Case A

The signaling molecule is inhibitory. Neuron 1 releases glutamate. Neuron 2 releases dopamine.

Select the correct words in the questions below to check your understanding of neurotransmission:

The correct answers for Case A follow:

Case B

The signaling molecule is excitatory. Neuron 1 releases glutamate. Neuron 2 releases dopamine.

Select the correct words in the questions below to check your understanding of neurotransmission:

The correct answers for Case B follow:

Case C

The signaling molecule is inhibitory. Neuron 1 releases GABA. Neuron 2 releases dopamine.

Select the correct words in the questions below to check your understanding of neurotransmission:

The correct answers for Case C follow:

Case D

The signaling molecule is excitatory. Neuron 1 releases GABA. Neuron 2 releases dopamine.

Select the correct words in the questions below to check your understanding of neurotransmission:

The correct answers for Case D follow:
