MesoNet: dual-threshold spike routing

upper / lower threshold → separate event routes. check each pathway alone, then alternate; resets could make this weird

recorded design: an upper threshold emits a positive event and a lower threshold emits a negative event. Route the event types separately so the receiving synapses can apply different effects and weight updates.

pointers: Brian2 custom events, equation definitions and synaptic pathways. The journal reports an initial qualitative stability improvement but also notes oscillation risks and tuning requirements; it does not supply a validated parameter set.

reference test cases: excite only the positive pathway, then only the negative pathway, then alternate both; inspect event counts, membrane state, reset behavior and weight changes. These are proposed review cases to make the implementation inspectable.

Signed synaptic pathways and integration error

open question: are polarity and anatomical excitatory/inhibitory identity intended to be equivalent in this model? State the modeling assumption explicitly instead of inferring biological plausibility from signed events alone.
