Messages passed amongst neurons in the brain can be recorded using an external electrode, and they show up as a series of spikes of equal magnitude. These spikes can be modelled by a Poisson random variable with rate 6000 spikes per minute. The PMF of the Poisson RV is given by: P(N = k) for k= 0, 1, 2, ... (a) What is the probability of recording no spikes in the first 100 milliseconds? (b) What is the probability of recording between 5 to 10 spikes (both included) in the [300ms, 400ms] time range? ake-a k! = (1) Leave your answers as an expression in terms of a sum of 1 or more exponentials. Hint: The parameter a of the Poisson RV is the average number of event occurrences in a specified time interval, so utilize the given information to find out this parameter.
