WebSince the SFC is normalized for both spike rate and LFP power it is immune to changes in those parameters. The SFC measures phase-synchronization between spikes and LFP oscillations as a function of frequency. It ranges from 0 for a complete lack of synchronization, to 1 for perfect phase synchronization. WebWe show that: (i) humans can volitionally increase the firing rate of arbitrary individual neurons in these regions; (ii) as with all forms of instrumental learning, only a subset of participants learn the task (learners); and (iii) only learners demonstrated an increase in local spike field coherence (SFC), with the strongest SFC in the beta ...
