Article
The hippocampus plays a critical role in supporting episodic memory, in large part by binding together experiences and items with surrounding contextual information. At present, however, little is known about the roles of different hippocampal subfields in supporting this item–context binding. To address this question, we constructed a task in whic...
Article
Our everyday memories can vary in terms of accuracy and phenomenology. According to one theoretical account, these differences hinge on whether the memories contain information about both an item itself as well as associated details (remember) versus those that are devoid of these associated contextual details (familiar). This distinction has been...

Our everyday memories can vary in terms of accuracy and phenomenology. One theoretical account that can help understand how to categorize these differences delineates between memories that are remembered versus familiar. This difference largely hinges on whether the memories contain information about both an item itself as well as associated detail...

Episodic memory depends on interactions between the hippocampus and interconnected neocortical regions. Here, using data-driven analyses of resting-state functional magnetic resonance imaging (fMRI) data, we identified the networks that interact with the hippocampus—the default mode network (DMN) and a “medial temporal network” (MTN) that included...

Episodic memory is thought to depend on interactions between the hippocampus and a set of closely interconnected regions that comprise the default mode network (DMN)--a large-scale network that has been identified with resting-state fMRI. Here, using data-driven analyses of resting-state fMRI data to characterize cortico-hippocampal network connect...
Article
Why do we sometimes easily retrieve memories, but other times appear to forget them? We often look to our external environment for retrieval cues, but another way to optimize memory retrieval is to be in a mental state, or mode, that prioritizes access to our internal representation of the world. Such a 'retrieval mode' was proposed by Endel Tulvin...

The hippocampus plays a critical role in supporting episodic memory. Although we know that temporal context is a defining feature of episodic memory, we understand relatively little about how this information may be represented by the hippocampus. Research in rodents has suggested that the hippocampus represents temporal information on an absolute...

Chapter
Representational similarity analysis (RSA) is a multivariate method that can be used to extract information about distributed patterns of representations across the brain. It is related to population vector analysis, a staple in the single-unit recording tradition. RSA is a flexible method that can be applied to many types of neuroimaging data, alt...
Article
Remembering is a complex process that involves recalling specific details, such as who you were with when you celebrated your last birthday, as well as contextual information, such as the place where you celebrated. It is well established that the act of remembering enhances long-term retention of the retrieved information, but the neural and cogni...
Article
Evidence for false recognition within seconds of encoding suggests that semantic-associative influences are not restricted to long-term memory, consistent with unitary memory accounts but contrary to dual store models. The present study sought further relevant evidence using a modified free recall converging associates task where participants studi...
Article
Full-text available
The hippocampus plays a critical role in spatial and episodic memory. Mechanistic models predict that hippocampal subfields have computational specializations that differentially support memory. However, there is little empirical evidence suggesting differences between the subfields, particularly in humans. To clarify how hippocampal subfields supp...

Article
Young and older adults experience benefits in attention and memory for emotional compared to neutral information, but this memory benefit is greatly diminished in Alzheimer's disease (AD). Little is known about whether this impairment arises early or late in the time course between healthy aging and AD. This study compared memory for positive, nega...
Article
In order to determine if highly negative stigma is a more salient cue than other negative emotional, non-stigmatized cues, participants underwent EEG while passively viewing or actively regulating their emotional response to images of highly negative stigmatized (e.g., homeless individuals, substance abusers), or highly negative non-stigmatized (e....
Article
The award of the Nobel Prize to Professors John O'Keefe, May-Britt Moser, and Edvard Moser brings global recognition to one of the most significant success stories in modern neuroscience. Here, we consider how their findings, along with related studies of spatial cognition in rodents, have informed our understanding of the human hippocampus. Rather...
Article
Memory for emotional experiences often persists longer than memory for neutral experiences. The present study examined how encoding processes influence memory retention across 0.5- or 24-h delays and whether these processes differ between emotionally arousing and neutral information. Participants encoded items during an fMRI scan. Immediately follo...
