CH4: Psychopharmacology - communication between neurons

Drugs affect behavior by affecting synaptic transmission If you want to learn more check out How do you calculate stoichiometry?

⤷ Antagonists: Inhibit postsynaptic effects We also discuss several other topics like What is endomembrane system and its function?
Don't forget about the age old question of What are the relationships between kinetic energy and potential energy?

(decrease NT activity or block receptors)

⤷ Agonists: facilitate postsynaptic effects

(increase NT activity or bind in place of NT on receptors)Don't forget about the age old question of What are the key elements of recovery?

We also discuss several other topics like What is the loanable funds theory?

(aggy - you keep doing annoying things)Don't forget about the age old question of What is exponential growth halted by?

Helps receptors do what they need to

Effects on production of NT

(how drugs ⊕/⊖ NT synthesis)

  • NT are a product of precursors (agonist) controlled by enzymes
  • Some drugs act as precursors → produce more NT

Effect on Storage / Release of NT

Vesicle transporter

Move nt into vesicles

🞻 Don't confuse the two!

                                                            Transporter

                                                        Move NT in synapse into cytoplasm of pre.

Drugs (antagonist) block

Vesicle transporters - vesicles have no content and thus, nothing is released.

Others block NT release from the terminal. (deactivate proteins that allow docking)

Effects on Receptors

Direct Agonist: drug that mimics NT effect

Receptor Blocker / direct antagonist: drugs bind with postsynaptic and block activation.
