Lapses in perceptual decisions reflect exploration

S Pisupati, L Chartarifsky-Lynn, A Khanal… - Elife, 2021 - elifesciences.org
Perceptual decision-makers often display a constant rate of errors independent of evidence
strength. These 'lapses' are treated as a nuisance arising from noise tangential to the …

Neural substrates of Drosophila larval anemotaxis

T Jovanic, M Winding, A Cardona, JW Truman… - Current Biology, 2019 - cell.com
Animals use sensory information to move toward more favorable conditions. Drosophila
larvae can move up or down gradients of odors (chemotax), light (phototax), and …

A neural circuit architecture for rapid learning in goal-directed navigation

C Dan, BK Hulse, R Kappagantula, V Jayaraman… - Neuron, 2024 - cell.com
Anchoring goals to spatial representations enables flexible navigation but is challenging in
novel environments when both representations must be acquired simultaneously. We …

[PDF][PDF] Flexible control of behavioral variability mediated by an internal representation of head direction

C Dan, R Kappagantula, BK Hulse, V Jayaraman… - Biorxiv, 2021 - scholar.archive.org
Internal representations are thought to support the generation of flexible, long-timescale
behavioral patterns in both animals and artificial agents. Here, we present a novel …

[PDF][PDF] Using learning theories to advance psychotherapy theory and research

I Berwian, P Hitchcock, S Pisupati, G Schoen, Y Niv - 2023 - osf.io
Many psychotherapy interventions have a large evidence base and can help a substantial
number of people with psychiatric symptoms. However, we still have little understanding of …

Variance adaptation in navigational decision making

R Gepner, J Wolk, DS Wadekar, S Dvali, M Gershow - Elife, 2018 - elifesciences.org
Sensory systems relay information about the world to the brain, which enacts behaviors
through motor outputs. To maximize information transmission, sensory systems discard …

Generative models of birdsong learning link circadian fluctuations in song variability to changes in performance

S Brudner, J Pearson, R Mooney - PLOS Computational Biology, 2023 - journals.plos.org

Behavioral hallmarks of practice include exploratory variation and long-term improvements …

Generating synthetic aging trajectories with a weighted network model using cross-sectional data

S Farrell, A Mitnitski, K Rockwood, A Rutenberg - Scientific Reports, 2020 - nature.com
We develop a computational model of human aging that generates individual health
trajectories with a set of observed health attributes. Our model consists of a network of …

Dopamine depletion affects vocal acoustics and disrupts sensorimotor adaptation in songbirds

V Saravanan, LA Hoffmann, AL Jacob, GJ Berman… - ENeuro, 2019 - eneuro.org
Dopamine is hypothesized to convey error information in reinforcement learning tasks with
explicit appetitive or aversive cues. However, during motor skill learning feedback signals …
