Neurotransmitter pathways- Lecture 6

Question 1

why is brianwave activity not scattered randomly across the brain?

Answer 1

activity follow specific ‘pathways’, symmetrically arranged on both sides of the midline

Question 2

DESCRIBE the different types of Neurotransmitters

Answer 2

Types
 NS uses > 100 different NTs (and more might yet be discovered);
 Classification of NTs based on chemical structure:

(Quarternary- & Mono-) Amines (e.g., dopamine, serotonin, noradrenaline, acetylcholine (ACh))
o Amino Acids (e.g., GABA, glutamate)
o Peptide transmitters (e.g., endorphins, oxytocin)
o Gas transmitters (e.g., Nitric oxide (NO) and carbon monoxide (CO))

Not stored inside the neuron, but synthesised as needed (unlike small-molecule and peptide transmitters).
