Schematic illustration of the experimental setup. The ∼1-mm-thick aluminum panels of the electrically-grounded Faraday shielding provides an electromagnetically “quiet” environment. Three orthogonal sets of square coils ∼2 m on edge, following the design of Merritt et al. (1983), allow the ambient geomagnetic field to be altered around the participant’s head with high spatial uniformity; double-wrapping provides an active-sham for blinding of experimental conditions (Kirschvink, 1992b). Acoustic panels on the wall help reduce external noise from the building air ventilation system as well as internal noise due to echoing. A non-magnetic chair is supported on an elevated wooden base isolated from direct contact with the magnetic coils. The battery-powered EEG is located on a stool behind the participant and communicates with the recording computer via an optical fiber cable to a control room ∼20 m away. Additional details are available in Figure 2. This diagram and the center figure for the visual abstract was modified from the figure “Center of attraction,” by C. Bickel (Hand, 2016), with permission.

Empirical evidence of emotion-enhanced sensory cortex and amygdala recapitulation during memory retrieval. A, Conjunction fMRI analyses of brain activity associated with successful memory during encoding and retrieval revealed significant spatial overlap (i.e., recapitulation) in ventral temporo-occipital cortex for negative and positive emotional images (red, blue and turquoise clusters). The spatial extent of recapitulation across the visual stream was greater for negative (red clusters) than positive emotional stimuli (blue clusters). Areas associated with emotion-related recapitulation were also correlated with emotional enhancements (not differentiated by valence) in behavior (data and figure from Kark and Kensinger, 2015).
