Neuromodulatory systems, including the noradrenergic, serotonergic, dopaminergic, and
cholinergic systems, track environmental signals, such as risks, rewards, novelty, effort, and …

The scientific community is increasingly concerned with the proportion of published
“discoveries” that are not replicated in subsequent studies. The field of rodent behavioral …

Animals learn certain complex tasks remarkably fast, sometimes after a single experience.
What behavioral algorithms support this efficiency? Many contemporary studies based on …

The trade-off between the need to obtain new knowledge and the need to use that
knowledge to improve performance is one of the most basic trade-offs in nature, and optimal …

Welfare of lab animals has two major problems, which are general maintenance and
treatment technique during the experimental procedures. These problems are related to the …

Social behavior in mammals is often studied in pairs under artificial conditions, yet groups
may rely on more complicated social structures. Here, we use a novel system for tracking …

The nature and neural implementation of emotions is the subject of vigorous debate. Here,
we use Bayesian decision theory to address key complexities in this field and conceptualize …

We examined measures of locomotor and anxiety-like behavior in male and female mice of
15 inbred strains on the elevated-plus maze, light/dark transition box and open field. Strain …

Zebrafish (Danio rerio) are emerging as a useful model organism for neuroscience research.
Mounting evidence suggests that various traditional rodent paradigms may be adapted for …

Outside of the laboratory, animals behave in spaces where they can transition between
open areas and coverage as they interact with others. Replicating these conditions in the …
