Expand description

Izhikevich 2007 biophysical parameterisation (NeuroML izhikevich2007Cell): C dv/dt = k (v - vr)(v - vt) - u + I, du/dt = a (b (v - vr) - u), with a v >= vpeak -> v = c, u += d reset. RK4 over the coupled ODE. The right-hand side is exact arithmetic (products, a sum, a division — no transcendental functions), so simulate matches the Python reference bit-for-bit.

Implementations§

Source§

impl Izhikevich2007Rk4

Source

fn rhs(&self, v: f64, u: f64, current: f64) -> (f64, f64)

Source

pub fn step(&mut self, current: f64) -> i32

Source

pub fn simulate(&mut self, n_steps: usize, current: f64) -> (Vec<f64>, i64)

Run n_steps RK4 updates under a constant input, returning the v trace (already reset to c on spiking steps) and the spike count. Reuses step, so the trace is bit-identical to the per-step path and to the Python reference (the right-hand side is exact arithmetic). The final state is left in self.v / self.u.
