How neurons communicate

Ligand-operated channel

nicotinic Acetylcholine (cholinergic) Receptors (nAchR)

Neurons as computational units

Excitatory PostSynaptic Potential (EPSP) & (IPSP)

G-protein operating channel

Difference between Nicotinic Receptors (nAchRs) & Muscarinic Receptors (mAchRs)

Acetylcholine (Ach) biosynthesis

Nerve gas (Sarin)

Myasthenia Gravis & AchE inhibitors (Neostigmine)

Cholinergic system of the brain, (Ravistigmine)

MonoAmine neurotransmitters

Here comes the funny part

Inactivation of MonoAmines

Anti-depressants & Parkinson's & Alzheimer's drugs

Triple therapy of Parkinson's
