LFP activities in acute and chronically isolated neocortical slabs. a, Ketamine-xylazine anesthesia. LFPs recorded from intact anterior suprasylvian gyrus (top trace) and from neocortical slab (bottom trace) 1 h after isolation. b, LFPs recorded from intact cortex (top trace) and isolated neocortical slab (bottom trace) 7 d (168 h) after isolation during a transition from SWS to REM. c, d, Expanded fragments of activity shown in b. e, Active states per minute in the slab versus time since isolation in hours. Each point is an average for an hour and an animal. f, Histogram showing active states per minute grouped in time segments used for statistical analysis.
