If we consider neurons nodes and connections between them edges, are cycles (from graph theory) are possible in the brain?
To put it another way, would the signal generated from
neuron1 be able to travel around in a circuit of other neurons and come back to activate
neuron1 again? Or is this generally not possible because
neuron1 would still be recovering/re-potentiating?
If yes, as a programmer I would expect this to be the mechanism by which contiguous experience would be possible (ie. the main event loop of an application). Any studies/field/reseachers you could point me to for further research?
