is the site of communication between a neuron and a target cell

refers to the neuron sending the signal

refers to the target cell receiving the cignal

is a process whereby neurotransmitters get reabsorbed back into the presynaptic neuron they came from

If a neurotransmitter is ________, it will increase the likelihood that the neuron will fire action potential. ex: epinephrine and norepinephrine.

If a neurotransmitter is _______, it makes the likelihood of the neuron firing action potential will be decreased. ex: GABA and endorphins.

> If a neurotransmitter is a ________, this means it can affect a largenumber of neurons at the same time, as well as being able to influence the effects of other neurotransmitters. >do not directly activate the receptors of neurons but work together w/ neurotransmitters to enhance the excitatory or inhibitory responses of the receptors. ex:serotonin and dopamine.

>fight or flight >produced in stressful situations. Increases heart rate and blood flow, leading to physical boost and heightened awareness.

>calming >Calms firing neryes in the central nervous system. >High levels improve focus, low levels cause anxiety. >Also contributes to motor control and vision.

>affects attention and responding actions in the brain >contracts blood vessels increasing blood flow

> learning > involved in thought, learning and memory. > Activates muscle action in the body. > Also associated with attention and awakening.

> pleasure > feelings of pleasure, also addiction, movement and motivation > People repeat behaviors that lead to ______ release.

> memory > Most common neurotransmitter. > Involved in learning and memory, > regulates development and creation of nerve contacts.

> mood > contributes to well-being and happiness. > Helps sleepcycle and digestive system regulation > Affected by exercise and light exposure.

> euphoria > Released during exercise, excitement and sex producing well-being and euphoria, reducing pain

> is commonly prescribed to treat attention deficit hyperactivity disorder (ADHD). > It stimulates the release of neurotransmitters, particularly dopamine and norepinephrine, in the brain. > This increased release enhances focus, attention, and alertness by improving communication between neurons in the areas of the brain responsible for these functions.

> SSRI > used to treat depression. It works by blocking the reuptake of serotonin, a neurotransmitter associated with mood regulation. By preventing the reabsorption of serotonin, ______ increases the concentration of serotonin in the synaptic cleft, promoting improved mood and reducing symptoms of depression.

SSRI

> contains neurotransmitters > located in the axon terminal

> increase food intake > storage of energy as fat > reduce anxiety, stress
