Figure S5.
Readout of
‘identity information’ using the best 2, 4, 8, 16, 32, 64, or 128,
compared to readout using all 256 neurons, for ITC (A) and PFC
(B). As can be seen in A, identity information is less
compact in
ITC than abstract category information is (Fig. 4), while for PFC the
best 16 neurons seem to contain all the information in the population
of 256 neurons for both abstract category information and the amount of
identity information. As in Figure 4, the ‘best’ neurons were
determined based on an ANOVA between cats and dogs using the training
data. Due to the greedy manner the neurons were selected in,
and
the non-optimality of the selection method, the information represented
in the subsets of neurons is an underestimate of how much information
be present if the ‘real’ best n neurons were selected.
