Fig. 2: Examples of item and location-specific responses.
From: Concept and location neurons in the human brain provide the ‘what’ and ‘where’ in memory formation
A Selective responses by single neurons (top: amygdala, bottom: hippocampus), separated based on correct vs. incorrect subsequent retrieval. Solid lines (lower panels): response to the preferred item. Dashed lines: average response to all non-preferred items (cf. Fig. S1A). B Responses of single neurons in the PHC to spatial locations within the presentation grid. Solid lines (lower panels): response to the preferred item locations, which in the lower example includes the entire bottom row of the grid. Dashed lines: average response to all non-preferred locations (cf. Fig. S1B) Subsequent memory effects per neuron were statistically assessed using a one-sided Wilcoxon rank-sum test for the time window of 0 to 1500 ms. Statistically significant effects were found for the two item neurons (top, P = 0.008, Z = 2.40; bottom, P = 0.02, Z = 2.04), but not for the two location neurons (both P > 0.1, Z < 0.95). Source data are provided in a git repository (see Data Availablity).
