Geographically distributed circuit: return pathway. (a) BN firing rate with shadowed areas inidcating plasticity polarity at ABsyn (above the dashed line) and BAsyn (below the deshed line). (b) ANpost spiking frequency. An increase of spiking activity (expressed as percentage of variation) is observed in the middle of the run in coincidence with BN firing followed by a return to baseline. (c) BAsyn weight evolution. The low-rate spiking of BN and ANpost caused a strong depression trend (blue) only temporarily reverting to ‘none’ (black) during BN excitation and synchronization of the two neurons. X-axis common to all panels.
