Fig. 7. Removing single neurons does not disrupt decoded states.

(a) An example trial, with choice options of values 3 and 4. Colors indicate the value decoded at each point in time. The top row shows the values decoded from the full ensemble, and the rows beneath show the values decoded when each of eight neurons was held out. (b) For every neuron, a reduced ensemble was created by holding it out. Correlations were calculated between the time series of values decoded from the reduced ensemble and the corresponding full ensemble, and r² values are shown. (c) The average effects of holding different numbers of neurons out from the full ensemble. Each point is the average r² from one session, in which the same number of neurons were held out in different combinations. The black line is an exponential curve fit to the distribution. When 100% of neurons were removed, values were decoded from LFP data alone, and the minimum r² observed was 0.049.
