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 …

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 …

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 …

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 …

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 …

Localized and global representation of prior value, sensory evidence, and choice in male mouse cerebral cortex

K Ishizu, S Nishimoto, Y Ueoka, A Funamizu - Nature Communications, 2024 - nature.com
Adaptive behavior requires integrating prior knowledge of action outcomes and sensory
evidence for making decisions while maintaining prior knowledge for future actions. As …

Global neural encoding of behavioral strategies in mice during perceptual decision-making task with two different sensory patterns

S Wang, H Gao, Y Ueoka, K Ishizu, A Funamizu - iScience, 2024 - cell.com
When a simple model-free strategy does not provide sufficient outcomes, an inference-
based strategy estimating a hidden task structure becomes essential for optimizing choices …

ECoG activity distribution patterns detects global cortical responses following weak tactile inputs

A Mellbin, U Rongala, H Jörntell, F Bengtsson - Iscience, 2024 - cell.com
Many studies have suggested that the neocortex operates as a global network of functionally
interconnected neurons, indicating that any sensory input could shift activity distributions …

Prior probability cues bias sensory encoding with increasing task exposure

K Walsh, DP McGovern, J Dully, SP Kelly… - Elife, 2024 - elifesciences.org
