A novel experimental paradigm investigating how humans manage limited search capacity over many alternatives reveals close-to-optimal behaviours and identifies heuristics used to minimize computation with little impact on performance.
The bed nucleus of the stria terminalis (BNST) is required for the expression of defensive behavior to uncertain threats, a function that is central to pathological anxiety.
Digital reconstruction of environment combined with eye and head-tracking enabled the process of prey-detection and capture to be seen from the freely moving mouse’s point-of-view and shows the exact visual-field and retinal location mice use when chasing prey and the advantage.

Distinct computational levels of uncertainty compel agents to gain information about hidden states in the world (‘active inference’) or optimise their ‘world model’ as such (‘active learning’).

The biocontrol fungus Trichoderma atroviride possess a functional circadian clock, whose components impact the production of secondary metabolites and also play a role in the interaction with fungi such as the phytopathogen Botrytis cinerea.

Hippocampal BOLD activity reflects behavioral performance and feedback in a fast-paced timing task, supporting the formation of task-specific yet flexible and generalizable sensorimotor representations in real time.
The elongation rate of RNA Polymerase II varies greatly between and along genes, as this enzyme accelerates from stable pausing to rapid elongation within genes, and is influenced by CG-content, exons and chromatin.
Flow cytometric isolation and fate mapping shows that neurosphere-initiating cells are highly mitotically active and persist only transiently in vivo, and are distinct from quiescent, long-lived neural stem cells.

A mouse model of human muscle myopathy is used to provide mechanistic insight, identify possible biomarkers of disease, and suggest possible therapeutic strategies to alleviate muscle weakness.
Neuronal activity in the primate orbitofrontal cortex reveals different choice biases observed when offers are presented sequentially originate at different stages of the decision process.
