Reservoir Computing Properties of Neural Dynamics in Prefrontal Cortex
Fig 6
Example activities of reservoir and dACC neurons showing higher activity for feedback in COR1 trials.
Single neurons activities are averaged over incorrect (INC), first correct (COR1) and other correct (COR) trials and centered on the feedback (shaded areas correspond to SEM). A. Average activity of a dACC neuron showing a strong increase in activity after feedback for COR1 trials only (pairwise t-test with false discovery rate correction, COR1 > COR corrected p-value < 10−3, COR1 > INC corrected p-value < 10−5, Gaussian smoothing of firing rate with 35 ms standard deviation). B. Reservoir neuron from the model showing a significantly higher activity after feedback for COR1 trials (pairwise t-test with false discovery rate correction, COR1 > COR corrected p-value < 10−6, COR1 > INC corrected p-value < 10−15). C. Model readout neuron trained to activate specifically for the first reward, demonstrating the presence of the COR1 information in the reservoir.
