A Shared Threat-Anticipation Circuit Is Dynamically Engaged at Different Moments by Certain and Uncertain Threat Open
Temporal dynamics play a central role in models of emotion: “fear” is widely conceptualized as a phasic response to certain-and-imminent danger, whereas “anxiety” is a sustained response to uncertain-or-distal harm. Yet the underlying neur…

A neural oscillatory signature of sustained anxiety Open
Background Anxiety is a sustained response to uncertain threats; yet few studies have explored sustained neurobiological activities underlying anxious states, particularly spontaneous neural oscillations. To address this gap, we reanalysed…

Functional Connectivity of the Anterior and Posterior Hippocampus: Differential Effects of Glucose in Younger and Older Adults Open
The hippocampus features structurally and functionally distinct anterior and posterior segments. Relatively few studies have examined how these change during aging or in response to pharmacological interventions. Alterations in hippocampal…

Non-invasive Investigation of Human Hippocampal Rhythms Using Magnetoencephalography: A Review Open
Hippocampal rhythms are believed to support crucial cognitive processes including memory, navigation, and language. Due to the location of the hippocampus deep in the brain, studying hippocampal rhythms using non-invasive magnetoencephalog…

The functional role of human right hippocampal/parahippocampal theta rhythm in environmental encoding during virtual spatial navigation Open
Low frequency theta band oscillations (4–8 Hz) are thought to provide a timing mechanism for hippocampal place cell firing and to mediate the formation of spatial memory. In rodents, hippocampal theta has been shown to play an important ro…
