Grid-like Neural Representations Support Olfactory Navigation of a Two-Dimensional Odor Space.
Xiaojun Bao,Eva Gjorgieva,Laura K. Shanahan,James D. Howard,Thorsten Kahnt,Thorsten Kahnt,Jay A. Gottfried,Jay A. Gottfried +7 more
TL;DR: It is shown that human subjects can learn to navigate in olfactory space and form predictions of to-be-encountered smells, highlighting a unique neural mechanism by which odor information can be assembled into spatially navigable cognitive maps, optimizing orientation, and path finding toward an odor source.

Odor-evoked category reactivation in human ventromedial prefrontal cortex during sleep promotes memory consolidation.
Laura K. Shanahan,Eva Gjorgieva,Ken A. Paller,Thorsten Kahnt,Thorsten Kahnt,Jay A. Gottfried,Jay A. Gottfried +6 more
TL;DR: Using pattern analysis of fMRI ensemble activity, it is found that presentation of odor cues during sleep promotes reactivation of category-level information in ventromedial prefrontal cortex that significantly correlates with post-sleep memory performance.

Neural retrieval processes occur more rapidly for visual mental images that were previously encoded with high-vividness.
Eva Gjorgieva,Ricardo Morales-Torres,Roberto Cabeza,Marty G. Woldorff +3 more
TL;DR: Neural retrieval processes occur more rapidly for visual mental images encoded with high-vividness, characterized by faster reaction times and earlier alpha-band activity decrease, suggesting an earlier memory reinstatement and improved episodic memory.

Learning from mistakes: Incidental encoding reveals a time-dependent enhancement of posterror target processing.
Eva Gjorgieva,Tobias Egner +1 more
TL;DR: It is documented, for the first time, that making an error leads to a substantial enhancement of target (but not distracter) memory on the subsequent trial, which interacts with RSI.
The influence of imagery vividness and internally-directed attention on the neural mechanisms underlying the encoding of visual mental images into episodic memory.
TL;DR: The electroencephalography results clarify the neural mechanisms supporting the encoding of self-generated information and suggest that longer internally-directed attention is required to generate subsequently remembered low-vividness images.
