Figure 4. Relative timing of HFB response onset during episodic retrieval.

Figure 4

A) Histograms display the distribution of HFB ROL difference latencies (i.e., ROL delay), where each region of interest is compared to RSC/PCC, for the self-episodic condition. Each observation is therefore the HFB ROL difference, for a single trial, between a given RSC/PCC site and a given AG (upper left), SPL (upper right), visual (lower left) or motor (lower right) site. B) Probability density functions for each ROL difference distribution. These distributions suggest that compared to RSC/PCC, AG showed no lag or lead bias (delay) in response onset timing, unlike other control regions. C) Schematic representation of latency distributions (A–B), which suggest a sequence of HFB response onsets during episodic retrieval, where visual regions closely precede the near simultaneous onset of RSC/PCC and AG, followed by the engagement of SPL and finally motor cortex.
