    I’m in the +1 portion of my 4+1 program. We’re researching how attention and sensory input changes time perception, which includes our participant sitting in room doing nothing for an hour as a baseline, so we get more downtime than we’d like sometimes lmao.

    That’s a hard question because of the interconnected-ness and complexity of the systems but I’ll give it a shot.

    Neurotransmitters: ~30

    Neuromodulators: ~10-20 (some transmitters also act as modulators)

    Hormones: 10

    Growth Factors: ~5

    Endocannabinoids: 2

    Gaseous Neurotransmitters: 2

    Peptides: ~30

    Ion concentrations: ~5

    So all that together I want to say there’s about 100 or so distinct “analog” signaling systems, but a lot of these molecules can function in multiple capacities, like neurotransmitters can act as neuromodulators and etc.
