Adaptation towards scale-free dynamics improves cortical stimulus discrimination at the cost of reduced detection

Adaptation enhances discrimination at the cost of reduced detection: MUA rate coding.
(A) Based on the entire recording for each turtle, the LFP count per 1 second time window is strongly correlated with the MUA spike count per 1 second. MUA was generally lower rate than LFP. Each shaded region corresponds to one experiment. The vertical extents of the shaded regions delineate quartiles. (B) Similar to our observations based on LFP peak response (Fig 3), we found that when response was defined based on MUA spike counts, detection is highest during the transient response and decreases as adaptation progresses to a steady state. The decrease in detection during the steady-state compared with LFP-based detection is likely due to the lower activity rate of MUA relative to LFP. (C) MUA spike response also exhibited increased discrimination during the steady state compared with the transient.
