| Question | Answer |
| Effective Dose (ED) | % of people for whom a particular dose will cause the desired effects. (If ED50 for Fluoxetine is 150mg, 50% of population will be effected.) |
| Lethal Dose (LD) | % of fatalities at a drug dose. |
| Safety Margin | Difference between ED50 and LD1 |
| Potency | The strength of binding between a drug (ligand) and the target (receptor). |
| Efficacy | The biological effect exerted by the binding. |
| Bioavailability | This is how well the drug gets into the brain and to its site of action. |
| Agonist | Drug binds to receptor and mimics the neurotransmitter. |
| Antagonist | Drug binds to receptor but produces no biologic effect. |
| Inverse Agonist | Produces an effect which is opposite the effect of the agonist. |
| Saturability | Saturation occurs when all receptors are occupied. |
| Selectivity | Receptors are selective for specific drugs. |
| Reversability | Binding is usually reversible. |
| Synapse | Space between bouton and receptor site. |
| Mitochondria | Essentially the energy source of a neuron. |
| Blood-Brain Barrier | A protective network of blood vessels and cells that filters blood flowing to the brain. |
| Depolarization | Pushing membrane toward 0. |
| Hyperpolarization | Pushing membrane away from 0. |
| Transmembrane Potential | -70 mV (-70 x 100 billion neurons). Maintained by active processes such as membrane ion pumps. |
| Transduction | translating one form of energy into another |
| Exocytosis | When vesicles which contain neurotransmitters go to the surface of the membrane and release into the synapse. |
| Synapse | must have vesicles and membrane thickening |
| Microglia | (Glial cell) tiny, move through brain easily, perform phagocytosis |
| Phagocytosis | eating of dead tissue |
| Nodes of Ranvier | The gaps formed between myelin sheath cells along the axons. |
| Myelin | fatty sheaths that coat axons to promote faster conduction. |
| Temporal Summation | Administering another stimulus before the action potential of previous stimulus begins to recede. |
