MATH 190 Lecture Notes - Lecture 20: Acetylcholine, Electrical Synapse, Serotonin Receptor Agonist
Document Summary
Ipsp gaba, epsp leading to hyperpolarisation more negative ap harder to achieve; chloride enters cell as to make it more negative. 3 types: amino acids (gaba, glu, gly) Glycine: also inhibitor, more in spinal cord, brain stem, retina. Glutamate: major excitatory nt, also very important for learning (e. g. motor skills, able to push for example channels that have already formed around: amines (ach, da, epi, hist, ne, and 5-ht) Dopamine: excitatory nt, substantia nigra and tegmental area; movement and motivation (reward); different types of reaction, as there are different types of receptors in different brain areas; schizophrenia linked to dompaninergic abnormalities. Serotonin (5-ht): gastrointestinal tract and cns; mood, appetite, muscle contraction, sleep, and more (basically everything); depression (and fear) Histamine: immune response, allergies; really activates you. Lecture 2 b&a neurotransmission and neuropharmaca. Acetylcholine: most important nt in neuro-muscular junction of pns; in cns linked to memory and learning; excitatory nt.
