Description
Summary:<p><b>a</b>, Histogram of the MCPC activity of the unclamped input neuron <i>x</i><sub>0</sub> in the linear model given in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1012532#pcbi.1012532.g001" target="_blank">Fig 1a</a> with parameters {<i>W</i><sub>0</sub> = 2, <i>μ</i> = 0.5} obtained over 10,000 timesteps. <b>b</b>, Activity patterns generated by a model trained on MNIST displayed for time points separated by 3,000 timesteps. The samples of the MNIST-trained model display the probability of a sensory neuron being equal to one. Animation of the MCPC’s unclamped input activity can be found in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1012532#pcbi.1012532.s011" target="_blank">S4 Video</a> and <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1012532#pcbi.1012532.s012" target="_blank">S5 Video</a>.</p>
