Mechanism of Neurotransmitters

Neurotransmitters are chemical messengers that allow neurons to communicate.

Short version:

Neuronal signal → neurotransmitter released → binds to receptors → activates or inhibits → gets removed.

Their mechanism has 4 main steps:

1. Release

2. Binding

3. Effect

4. Removal

When an electrical signal (action potential) reaches the end of a neuron:

• Vesicles open
• Neurotransmitters are released into the synapse (the gap between neurons)

1. Release

Neurotransmitters cross the synapse and bind to receptors on the next neuron.

This binding tells the next neuron what to do.

2. Binding

Depending on the neurotransmitter, the next neuron:

• Fires (excitatory)
• Stops firing (inhibitory)

Examples:

• Glutamate → excitatory
• GABA → inhibitory

3. Effect

To stop the message, the neurotransmitter is removed by:

• Reuptake (taken back into the original neuron)
• Enzyme breakdown
• Diffusion away from the synapse

4. Removal

The combined effect of two drugs (or stimuli) is exactly equal to the sum of their individual effects.

Example:
Drug A produces 2 units of effect.
Drug B produces 3 units of effect.
Together → 2 + 3 = 5 (additive)

Additive Effect

The combined effect is less than the sum of the two drugs.

Example:
A = 2
B = 3
Together → 4 (instead of 5)

Infra-additive Effect

(Sub-additive)

The combined effect is greater than the sum of both drugs.

Example:
A = 2
B = 3
Together → 8 (instead of 5)

Supra-additive Effect

(Super-additive / Synergistic)

• Additive:
• Infra-additive:
• Supra-additive:

• Additive: A + B = A+B
• Infra-additive: A + B < A+B
• Supra-additive: A + B > A+B

Neurotransmitters are chemical messengers that allow neurons to communicate.

Short version:

Neuronal signal → neurotransmitter released → binds to receptors → activates or inhibits → gets removed.

Mechanism of Neurotransmitters

chemicals that send messages between neurons.

Neurotransmitters

Neurotransmitters can

• Excite a neuron (make it fire)
• Inhibit a neuron (stop it from firing)
• Modulate activity (adjust mood, movement, attention, etc.)

• Dopamine → reward, movement
• Serotonin → mood, sleep
• GABA → inhibition, calming
• Glutamate → excitation, learning
• Acetylcholine → memory, muscle activation
• Norepinephrine → alertness, stress response

Neurotransmitters - Main Types (examples)

Produces predictable patterns of behavior to evaluate effects of drugs

Experimental Analysis of Behavior (EAB)

It is a reduced response to a drug over time, leading to needing higher doses for the same effect.

Tolerance

Can be additive (simply added), infra- additive (less than), or supra-additive (greater than)

Drug Interactions

It is the amount of drug needed for an effect, while peak efficacy is the maximum effect a drug can produce.

Potency and Peak Efficiency

Causes withdrawal symptoms upon stopping, while psychological dependence is an emotional or mental urge to use the drug.

Physical and Psychological Dependence:

Neurons are the basic units of the nervous system, and neurotransmitters are chemicals that transmit signals between neurons.
