Figure 1 A Cross-Modal Code for Working Memory Left panels illustrate the behavioral task (Vergara et al., 2016). The monkey is required to compare the frequency of two stimuli presented in sequence, with a delay period between them. The stimuli may be tactile or auditory, requiring the monkey to make a cross-modal comparison. Right panels represent schematically the responses of a single neuron in the pre-supplementary motor area. Discharge rate is shown (top) when an auditory stimulus was presented first (purple bar) followed by a tactile stimulus (blue bar), or vice versa (bottom). Responses of the neuron during the delay period were modulated monotonically depending on the frequency of the stimulus, adhering to the same monotonic code of firing rate as a function of frequency for both the remembered auditory and tactile stimuli.
