What is nervous system & neurons?

100
Plays a role in mood, appetite, sleep and dreams, also linked with depression with certain levels.

What is serotonin? 

100

The bundles of neural fibers associated with left and righ hemispheric brain communication. 

What is corpus callosum?

100

Enhances the actions of neurotransmitters by mimicking/binding with receptor neurons or blocking reuptake from sending neurons.

What are agonist? direct and indirect

100

These two can act as agonist for ACh Acetylcholine. stimulating muscular and heart rate activity, they are both fatal.

What is black widow venom and nicotine? 

200

This is the pleasure and reward neurotransmitter; A lack of it is associated with Parkinson's disease, and too much is linked with schizophrenia.

What is dopamine? 

200

A hormone and a neurotransmitter; A boost of energy comes from this chemical messenger and is the primary chemical in "fight or flight" responses. 

What is epinephrine / adrenaline? 

200
In general, inhibit the actions of neurotransmitters. Binds to receptors as a blocking transmission to neuron, or prevents neurons from firing.

What are antagonist? 

200

The indirect way a drug/substance can act as an agonist is this. Prozac, for example blocks serotonin from being reabsorbed into the sending neuron.

What are reuptake inhibitors?

300

This neural chemical messenger associated with learning and memory, as well as other  functions like movement.

What is acetycholine?

300

This abundant excitatory messenger is involved in learning and memory by strengthening synaptic connections.

What is glutamate? 

300

This toxin essentially acts as an antagonist of acetycholine; effectively freezing/paralyzing muscles 

What is botox? 

300

This illicit drug substance is known to  prevent dopamine from being reabsorbed into the presynaptic neuron leading to overflow of dopamine in the synapse.

What is cocaine? 

400

The body's pain reduction chemical messenger. Can be stimulated by prolonged exercise/ running creating a euphoric sensation.

What are endorphins? 

400

Associated with anxiety-related  disorders this is the most abundant inhibitory transmitter. 

What is GABA / gamma aminobutyric acid?

400

A drug used as antagonist to dopamine. Believed to decrease hallucination and delusional thoughts in early schizophrenia patients.

What is thorazine? 

500

The chemial messenger involved in heightened sensitivity, arousal and alertness. Low levels associated with depression, but not necessarily a causal relationship. 

What is norepinephrine / noradrenaline? 

500

The two drugs which act as agonist for ACh acetylcholine and endorphins.

What is heroin and nicotine?
