The central idea of projecting the neural data onto a lower dimensional space (e.g. principal component analysis) is to reduce the dimensionality of a data set consisting of a large number of interrelated variables, while retaining as much as possible of the variation present that could be attributed to the stimulus that evoked this neural activity.

Certain features of single neuron firing violate the independent spike hypothesis of a Poisson neuron. Among these features (check all that apply):

In the Kalman filter,

The discriminability index in hypothesis testing provides a complete characterization of the decoding of a signal assuming that the noise follows a normal (Gaussian) distribution with a fixed variance, independent of the signal strength In the graphs below, different signal detection thresholds are shown. Check all that apply: A     B     C        

When you average single neuron responses to different stimuli, you get
