Generative replay across hippocampal-neocortical circuits

The paper shows that generative replay occurs in primary visual cortex during sleep, influenced by hippocampal activity, suggesting a mechanism for building hierarchical generative models for flexible behavior.

Synaptic histamine shapes the neurocomputational dynamics of human learning

This study shows how increased synaptic histamine affects hippocampal dynamics and learning by using a causal probe and analyzing neurocomputational strategies.

A learning-evoked slow-oscillatory architecture paces population activity for offline reactivation across the human medial temporal lobe

The paper identifies a slow-oscillatory architecture in the human medial temporal lobe that coordinates population activity during learning and facilitates offline reactivation and recall.

Noradrenaline causes a spread of association in the hippocampal cognitive map

This paper shows that noradrenaline causes a spread of association in the hippocampal cognitive map, leading to overgeneralisation errors and predicted by physiological markers.

A hierarchical coordinate system for sequence memory in human entorhinal cortex.

The paper shows that a hierarchical coordinate system in the human entorhinal cortex supports abstract sequence memories, mirroring spatial memory organization.

Memory consolidation during rest forms shortcuts in a cognitive map

This study shows that memory consolidation during rest creates shortcuts in the cognitive map, enabling novel inferences but limiting adaptability to environmental changes.

tDCS induced GABA change is associated with the simulated electric field in M1, an effect mediated by grey matter volume in the MRS voxel

This paper investigates how the electric field induced by tDCS in the motor cortex correlates with changes in GABA levels, finding that grey matter volume modulates this relationship.

A mechanism for hippocampal memory recall based on excitatory-inhibitory fluctuations in neocortex

The paper shows that hippocampal activity predicts excitatory-inhibitory fluctuations in visual cortex during memory recall.

The hippocampus and neocortical inhibitory engrams protect against memory interference

This study identifies two mechanisms involving the hippocampus and neocortex that protect against memory interference by organizing contextual representations and modulating neocortical inhibition.

Inhibitory Engrams In Perception And Memory.

This paper explores the role of inhibitory engrams in perception and memory, showing they regulate behavior and memory storage through balanced neural activity.
