Left-lateralized frontoparietal theta oscillations are thought to play an important role in verbal working memory. We causally tested this idea by stimulating the frontoparietal theta network at individual theta frequencies (4 to 8 Hz) during verbal working memory and observing the subsequent behavioral and neurophysiological effects. Weak electric...

... Design. As illustrated in Figure 1, the experiment employed a single-blind, cross-over, and sham-controlled design. It consisted of four study sessions with 1 week between consecutive sessions. ...

... Verbal WM Task. In each of the four study sessions, participants performed a Sternberg WM task ( Figure 1B). In this task, each trial started with a fixation cross presented at the center of the screen for 1 s, followed by a 2 s presentation of the memory set, which contained two, four, or six uppercase consonant letters placed with equal probability in any of six positions arranged in a circle centered on the fixation cross. ...

Yogic and meditative traditions have long held that the fluctuations of the breath and the mind are intimately related. While respiratory modulation of cortical activity and attentional switching are established, the extent to which electrophysiological markers of attention exhibit synchronization with respiration is unknown. To this end, we examin...
