Greater Interference From Multiple Exposures During Memory Retrieval Drives More Memorable and Forgettable Experiences [0.03%]
多重暴露干扰在记忆提取过程中产生更令人难忘和容易遗忘的经历

Our everyday experiences share many overlapping features, as we often engage in repeated activities and routines. This leads to interference across our experiences, making it difficult to remember specific, unique events. Hippocampal patter...

After fear conditioning, repeated presentation of the conditioned stimulus (CS) alone produces a context-dependent extinction of learned fear. The hippocampus has a critical role in this process, but the mechanism by which contextual inform...

Memories are stored in a sparse population of neurons active at the time of an event, an engram ensemble, and reactivation of the engram ensemble drives memory recall. Although the amygdala is essential for fear memory encoding and recall, ...

The ventral subiculum has long been appreciated as the major output structure of the ventral hippocampus but remains greatly understudied relative to the other hippocampal subregions. Over the last decade, investigation into ventral subicul...
Entorhinal Silencing Reveals Energy Cascade Organization of Hippocampal Oscillations [0.03%]

Hippocampal theta and gamma rhythms are often viewed as discrete channels supporting distinct cognitive operations. In particular, "gamma multiplexing" models propose that slow and fast gamma bands independently encode separate information ...

Evolution sculpts the brain's sensory adaptations. Because these adaptations differ markedly across species, it is challenging for humans to fully comprehend how other animals perceive the world. For a nocturnal mouse, the subjective sensor...
Distinct Patterns of Evoked Firing in Engram and Non-Engram Neurons in the Dentate Gyrus of Hippocampal Slices [0.03%]

Intense electrical activity modifies the cellular properties of neurons to enable the nervous system to store information. The dentate gyrus (DG) plays a role in learning and memory and its principal cell type, the granule cell (GC), can fi...

The epigenome provides the brain with a nucleus-templated form of plasticity that is of fundamental importance for learning and memory. Of the various types of epigenetic modifications, elevations in histone acetylation have been shown to a...
Encoding and Retrieval Dynamics During Frontal-Hippocampal Learning: Causal Modeling of Brain Networks in Schizophrenia and Health [0.03%]

Hippocampal-based associative learning is a cornerstone of human behavior and is compromised in schizophrenia. Learning is subserved by time-driven brain network dynamics during encoding and retrieval of associations, but the impact of thes...
