\f1. It turns out that the behaviour of the neuron above when E; = Vieset can be written in terms of an integral: R t_tspike V(t) = .Vreset + = / E_T/Tmf(t = T)d'r (5) Tm 0 where tspike is the time of the last spike before . (We are offsetting in the integration bound so that 7 spans over time since the last spike.) Show that the above expression (5)) satisfies the differential equation @) and boundary conditions for general (not necessarily constant) I(t). Hint: All you need to do here is substitute for the two instances of V(t) in (4) and show that the two sides are equal. The \"Leibniz integral rule\" may be helpful for expanding the left hand side. Depending on your solution, you may also need to either use integration by parts or perform a substitution 7 t 7
