Developmental and genetic modulation of evidence integration dynamics in zebrafish sensorimotor decision-making

This study uses drift-diffusion modeling on larval zebrafish to show that evidence integration dynamics develop during early stages and are altered by disease-linked mutations.

Socio-cognitive models in a patch foraging setting: a case study for model selection and parameter identifiability methods

The paper investigates socio-cognitive mechanisms in collective foraging using agent-based models and evaluates model selection and parameter identifiability through Bayesian inference and Wasserstein distance.

Resource depletion accelerates rate learning but not composition learning in patch foraging

This paper develops a Bayesian model of foraging in a patchy environment, showing resource depletion accelerates rate learning but not composition learning.

Environmental statistics and sensory experience shape patch foraging strategies in Drosophila larvae

This study shows Drosophila larvae adjust foraging behavior based on resource quality, valence, and prior experience, using a simple integration model.

How to Forage for a Mate?

This paper frames mate choice as a foraging problem and presents a mechanistic theory of decision-making in mate selection, showing how decision thresholds influence mating strategies based on signal availability.

Habitat structure and social behavior - the development of social phenotypes in the desert locust

This study shows that habitat structure influences social behavior and molecular pathways in desert locusts, leading to differences in group dynamics and gene expression.

Computational Urban Ecology of New York City Rats

The paper studies urban rats in New York City using thermal imaging and AI to analyze movement and social communication patterns.

Social patch foraging theory in an egalitarian group

The paper develops a stochastic model of social foraging in egalitarian groups, showing how social coupling affects group cohesion and foraging efficiency across different environmental conditions.

Patchy Perception: Rethinking Eye Movements through the Lens of Foraging Theory

This paper reframes eye movements as patch foraging behaviors, showing participants spend more time on informationally rich stimuli and minimize travel time to high-value targets.

Social hierarchy shapes foraging decisions

This study develops a model to show how social hierarchy influences foraging decisions, finding that follower-leader dynamics improve accuracy but misinformation reduces individual benefit and increases group cohesion.

Chronic brain functional ultrasound imaging in freely moving rodents performing cognitive tasks

This study validates chronic functional ultrasound imaging in freely moving rodents during cognitive tasks, showing stable recordings and nonlinear relationships between brain dynamics and task difficulty.

Active neural coordination of motor behaviors with internal states

The paper investigates how the brain coordinates motor behaviors with internal states, finding that brain activity drives movements and heart rate more than vice versa.

Social-vocal brain networks in a non-human primate

The paper identifies a social-vocal brain network in marmoset monkeys that distinguishes social contexts and modulates vocalizations.

Stable choice coding during changes of mind

This study investigates how rats represent provisional decisions in dynamic environments, finding that Frontal Orienting Fields (FOF) encode evidence with temporal gain modulation and rapidly update during changes of mind.

Rats optimally accumulate and discount evidence in a dynamic environment

This study shows rats can optimally accumulate and discount evidence in dynamic environments by adjusting their timescales based on environmental statistics and noise.
