Time domain activity variation per task within the human hippocampus (anterior and posterior partitions) reveals distinct patterns of specificity across tasks. Time activity magnitude peaks per hippocampus individual contact and task condition are represented. Time-activity peaks for the different tasks were defined as the max magnitude 2SD above mean baseline magnitude. We then count the number of peaks over threshold per task and statistical analysis revealed significant task activation above the baseline (dotted grey line in the plots). Plots represent normalized data and each task maximum magnitude (scale is 0:0.25:1 for the individual plots and 0:0.2:1 for the superimposed plot). The last panel represent all tasks overlaid for sake of visual comparison and report the number of subjects (N) contributing to each contact results. Note that distinct contacts within hippocampus have high preference for different tasks.
