      abstract     = {Pre-stimulus theta (4-8Hz) power in the hippocampus and
                      neocortex predicts whether a memory for a subsequent event
                      will be formed. Anatomical studies reveal
                      thalamus-hippocampal connectivity, and lesion, neuroimaging,
                      and electrophysiological studies show that memory processing
                      involves the dorsomedial (DMTN) and anterior thalamic nuclei
                      (ATN). The small size and deep location of these nuclei have
                      limited real-time study of their activity, however, and it
                      is unknown whether pre-stimulus theta power predictive of
                      successful memory formation is also found in these
                      subcortical structures. We recorded human
                      electrophysiological data from the DMTN and ATN of 7
                      patients receiving deep brain stimulation for refractory
                      epilepsy. We found that greater pre-stimulus theta power in
                      the right DMTN was associated with successful memory
                      encoding, predicting both behavioral outcome and
                      post-stimulus correlates of successful memory formation. In
                      particular, significant correlations were observed between
                      right DMTN theta power and both frontal theta and right ATN
                      gamma (32-50Hz) phase alignment, and frontal-ATN theta-gamma
                      cross-frequency coupling. We draw the following primary
                      conclusions. Our results provide direct electrophysiological
                      evidence in humans of a role for the DMTN as well as the ATN
                      in memory formation. Furthermore, prediction of subsequent
                      memory performance by pre-stimulus thalamic oscillations
                      provides evidence that post-stimulus differences in thalamic
                      activity that index successful and unsuccessful encoding
                      reflect brain processes specifically underpinning memory
                      formation. Finally, the findings broaden the understanding
                      of brain states that facilitate memory encoding to include
                      subcortical as well as cortical structures.},
