Back

Neuropharmacology is the study of how drugs affect the nervous system and behavior.

Front

What are neurotransmitters?

Back

Neurotransmitters are chemical messengers that transmit signals across a synapse from one neuron to another.

Front

What is the role of excitatory neurotransmitters?

Back

Excitatory neurotransmitters increase the likelihood that the receiving neuron will fire an action potential.

Front

What is the role of inhibitory neurotransmitters?

Back

Inhibitory neurotransmitters decrease the likelihood that the receiving neuron will fire an action potential.

Front

Give an example of an excitatory neurotransmitter.

Back

Glutamate is an example of an excitatory neurotransmitter.

Front

Give an example of an inhibitory neurotransmitter.

Back

GABA (gamma-aminobutyric acid) is an example of an inhibitory neurotransmitter.

Front

What is the function of serotonin in the brain?

Back

Serotonin is involved in mood regulation, sleep, and appetite.

Front

What is norepinephrine's role in the body?

Back

Norepinephrine is involved in the 'Fight or Flight' response, increasing heart rate and blood flow.

Front

What condition is characterized by an imbalance of excitatory and inhibitory neurons?

Back

Autism can be characterized by an imbalance of excitatory and inhibitory neurons.

Front

What is the effect of acetylcholine in the nervous system?

Back

Acetylcholine can act as both an excitatory and inhibitory neurotransmitter, affecting muscle activation and heart rate.
