Perceiving and Acting in the real world: from neural activity to behavior
One remarkable ability of the human brain is to process large amounts of information about our surroundings to allow us to interact effectively with them. In everyday life, the most common way to interact with objects is by reaching, grasping,...

Temporally restricted dopaminergic control of reward-conditioned movements
In mice that have undergone Pavlovian reward conditioning, dopaminergic neurons regulate conditioned movements in a temporally restricted manner, consistent with a primary contribution to associative learning rather than online movement generation.
Targeted Stimulation of Human Orbitofrontal Networks Disrupts Outcome-Guided Behavior
Howard et al. show that indirectly targeting orbitofrontal cortex (OFC) with TMS disrupts
choices that require inference without affecting value-based choices in general. Moreover,
TMS reduces OFC network connectivity, and the magnitude of this...
Inhibitory microcircuits for top-down plasticity of sensory representations
Rewards can improve stimulus processing in early sensory areas but the underlying neural circuit mechanisms are unknown. Here, the authors build a computational model of layer 2/3 primary visual cortex and suggest that plastic inhibitory circuits...
Origin of perseveration in the trade-off between reward and complexity
When humans and other animals make repeated choices, they tend to repeat previously chosen actions independently of their reward history. This paper locates the origin of perseveration in a trade-off between two computational goals: maximizing...

Word contexts enhance the neural representation of individual letters in early visual cortex
Letters are more easily identified when embedded in a word. Here, the authors show that word contexts can enhance letter information in early visual cortex, suggesting that the advantage offered by words occurs already during early perceptual...
Psilocybin induces time-dependent changes in global functional connectivity
The use of Psilocybin in scientific and experimental clinical contexts has triggered
renewed interest in the mechanism of action of psychedelics. However, its time-dependent
systems-level neurobiology remains sparsely investigated in humans.
Why Evolutionary Psychology (Probably) Isn’t Possible
Evolutionary psychologists have not shown that there are specific psychological programs that are written in the genetic foundation of our species. This is the challenge they must meet.

Sensory and Behavioral Components of Neocortical Signal Flow in Discrimination Tasks with Short-term Memory
In neocortex, each sensory modality engages distinct primary and secondary areas that route information further to association areas. Where signal flow may converge for maintaining information in short-term memory and how behavior may influence...
Adaptive repulsion of long-term memory representations is triggered by event similarity
We tested whether similarity between events triggers an adaptive repulsion of long-term memories. Subjects completed an associative learning task in which objects were paired with faces. Critically, the objects consisted of pairs that were identical...
