Population coding olfaction
WebSep 23, 2016 · Here we present evidence that this is in fact the case, showing that: 1) population coding analysis allows us to identify both WHETHER the rat will gape in response to taste stimulation and precisely WHEN (r=0.75) that gape will occur, in single trials; 2) using cuing to manipulate the latency of gaping has an almost identical impact on neural … WebDefine Network. Let’s compare the performance of a pair of networks both with and without population coding, and train them for one single time step. from snntorch import surrogate # network parameters num_inputs = 28*28 num_hidden = 128 num_outputs = 10 num_steps = 1 # spiking neuron parameters beta = 0.9 # neuron decay rate grad = surrogate ...

WebPopulation Coding. Population coding is a means by which information is coded in a group of neurons. In population coding, each neuron has a distribution of responses over some set of inputs, and the responses of many neurons may be combined to determine some value about the inputs.
