Hippocampal Replay Is Not a Simple Function of Experience
Replay of behavioral sequences in the hippocampus during sharp wave ripple complexes (SWRs) provides a potential mechanism for memory consolidation and the learning of knowledge structures. CurrentExpand

Segmentation of spatial experience by hippocampal theta sequences
The encoding and storage of experience by the hippocampus is essential for the formation of episodic memories and the transformation of individual experiences into semantic structures such as mapsExpand

Internally generated sequences in learning and executing goal-directed behavior
A network of brain structures including hippocampus (HC), prefrontal cortex, and striatum controls goal-directed behavior and decision making. However, the neural mechanisms underlying theseExpand

Risk-Responsive Orbitofrontal Neurons Track Acquired Salience
Decision making is impacted by uncertainty and risk (i.e., variance). Activity in the orbitofrontal cortex, an area implicated in decision making, covaries with these quantities. However, thisExpand

Triple Dissociation of Information Processing in Dorsal Striatum, Ventral Striatum, and Hippocampus on a Learned Spatial Decision Task
Decision-making studies across different domains suggest that decisions can arise from multiple, parallel systems in the brain: a flexible system utilizing action-outcome expectancies and a moreExpand

The Head-Direction Signal Plays a Functional Role as a Neural Compass during Navigation
The rat limbic system contains head direction (HD) cells that fire according to heading in the horizontal plane, and these cells are thought to provide animals with an internal compass. Previous workExpand

Adaptive Integration in the Visual Cortex by Depressing Recurrent Cortical Circuits
TLDR
Neurons in the visual cortex receive a large amount of input from recurrent connections, yet the functional role of these connections remains unclear. Expand

Adaptive properties of differential learning rates for positive and negative outcomes
TLDR
We show that the optimal learning rate asymmetry depends on the reward distribution and implement a biologically plausible algorithm that adapts the balance of positive and negative learning rates from experience. Expand

The Head-Direction Signal Plays a Functional Role as a Neural Compass during Navigation
(Current Biology 27, 1259–1267; May 8, 2017) Due to an oversight during the proofing process for this article, the first ‘‘Standard, Laser Off’’ panel in Figure 2B (upper left) was inadvertentlyExpand

Hippocampal projections to the ventral striatum: from spatial memory to motivated behavior
Multiple regions of the hippocampal formation project to the ventral striatum, a central node in brain circuits that subserve aspects of motivation. These projections emphasize information flow fromExpand
