In molluscan neurons, the carrier of inward current during the rising phase of the action potential is usually calcium.  This ion has an unusually steep concentration gradient.  Given the values below, what is the equilibrium potential for Ca2+ at 20 deg Celsius?   (Consider the options carefully.) o = 10-2 M          i = 1.7 x 10-7 M                o  log ——— = 4.77        i          i  log ——— = -4.77        o

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.
