Fig. 4From: Selective memory and behavioral alterations after ambient ultrafine particulate matter exposure in aged 3xTgAD Alzheimer’s disease miceRAM Reference Memory Errors: a Reference memory error analysis was split into acquisition phase (AP) and performance phase (PP) with approximate session division shown by dotted vertical line. Graph shows bins representing the mean errors from 3 consecutive sessions with the exception of bin 21, which is the average of 4, for a total of 64 sessions. Analysis of raw session data explored the slope component of each phase. b Mean reference memory errors of all performance phase sessions. Means ± SE. Only significant results are reported at top of the figure. n = 10–11 per groupBack to article page
