How deep is the brain? The shallow brain hypothesis

M Suzuki, CMA Pennartz, J Aru - Nature Reviews Neuroscience, 2023 - nature.com
Deep learning and predictive coding architectures commonly assume that inference in
neural networks is hierarchical. However, largely neglected in deep learning and predictive …

Trial-history biases in evidence accumulation can give rise to apparent lapses in decision-making

D Gupta, B DePasquale, CD Kopec… - Nature communications, 2024 - nature.com
Trial history biases and lapses are two of the most common suboptimalities observed during
perceptual decision-making. These suboptimalities are routinely assumed to arise from …

Sensory processing in humans and mice fluctuates between external and internal modes

V Weilnhammer, H Stuke, K Standvoss, P Sterzer - PLoS Biology, 2023 - journals.plos.org
Perception is known to cycle through periods of enhanced and reduced sensitivity to
external information. Here, we asked whether such slow fluctuations arise as a noise-related …

A brain-wide map of neural activity during complex behaviour

International Brain Laboratory, B Benson, J Benson… - biorxiv, 2023 - biorxiv.org
A key challenge in neuroscience is understanding how neurons in hundreds of
interconnected brain regions integrate sensory inputs with prior expectations to initiate …

Temporal regularities shape perceptual decisions and striatal dopamine signals

M Fritsche, A Majumdar, L Strickland… - Nature …, 2024 - nature.com
Perceptual decisions should depend on sensory evidence. However, such decisions are
also influenced by past choices and outcomes. These choice history biases may reflect …

Prior probability cues bias sensory encoding with increasing task exposure

K Walsh, DP McGovern, J Dully, SP Kelly… - Elife, 2024 - elifesciences.org
When observers have prior knowledge about the likely outcome of their perceptual
decisions, they exhibit robust behavioural biases in reaction time and choice accuracy …

Active reinforcement learning versus action bias and hysteresis: control with a mixture of experts and nonexperts

JT Colas, JP O'Doherty, ST Grafton - PLOS Computational Biology, 2024 - journals.plos.org
Active reinforcement learning enables dynamic prediction and control, where one should not
only maximize rewards but also minimize costs such as of inference, decisions, actions, and …

A common computational and neural anomaly across mouse models of autism

JP Noel, E Balzani, L Acerbi, J Benson… - bioRxiv, 2024 - biorxiv.org
Computational psychiatry has suggested that humans within the autism spectrum disorder
(ASD) inflexibly update their expectations (ie, Bayesian priors). Here, we leveraged high …

Flexible gating between subspaces in a neural network model of internally guided task switching

Y Liu, XJ Wang - Nature communications, 2024 - nature.com
Behavioral flexibility relies on the brain's ability to switch rapidly between multiple tasks,
even when the task rule is not explicitly cued but must be inferred through trial and error. The …

Open Data In Neurophysiology: Advancements, Solutions & Challenges

CJ Gillon, C Baker, R Ly, E Balzani, BW Brunton… - Ar**v, 2024 - pmc.ncbi.nlm.nih.gov
Across the life sciences, an ongoing effort over the last 50 years has made data and
methods more reproducible and transparent. This openness has led to transformative …
