The black v circles represent neurons. The red ϵ triangles represent activations (action potentials). Action potentials’ information content is shared between presynaptic neurons and postsynaptic neurons because activations are transmitted from the presynaptic neuron to the postsynaptic neuron.
The black arrows in the bottom diagram denote the physical creation of action potentials. The red arrows denote intra-neuron calculation of the gradient. Keep in mind that each neuron knows both the action potential it generates itself and the action potentials sent to it.
Oh that makes a lot more sense. Is delta v1 hat the change of v1 rather than a infintesimal? (Asking because if it was then it’d be easier to understand how it is calculated).
I’m confused. The bottom diagram seems to also involve bidirectional flow of information.
