Self-Supervised Learning Rules Uncover Hidden Hierarchical Structure in Data, Rivaling Backpropagation
Researchers found that layerwise self-supervised learning rules can match backpropagation's data efficiency in learning hierarchical structures, while remaining biologically plausible.
Why AI Says Naturalistic Experiments Are Key to Understanding Your Brain
A new paper from arXiv argues that naturalistic stimuli in cognitive science uncover mental processes that artificial lab tasks miss.
Virtual Reality and Cognitive Training Boost Brain Function in Parkinson's
A randomized clinical trial found that immersive virtual reality combined with adaptive cognitive training improved cognition and daily function in Parkinson's patients with mild cognitive impairment.
New Brain Model Unites Structure and Function for Deeper Cognitive Insights
Researchers propose functional whole-brain models (fWBMs) that combine realistic brain structure with task performance, aiming to bridge computational neuroscience and AI.
Von Economo Neurons Key to Reliable Social Skill Learning, AI Study Finds
A computational model shows that Von Economo neurons act as scaffolds for social skill acquisition, with implications for autism and frontotemporal dementia.
Hibernation Triggers Rapid, Reversible Brain Changes That Could Aid Stroke Recovery
A study reveals that hibernation causes rapid, reversible structural changes in visual neurons of squirrels, completely reversing within 1.5 hours of arousal and leaving no long-term deficits, offering insights for stroke recovery.
Parkinson's Drug Levodopa Reverses Memory Loss in Alzheimer's Study
New research identifies dopamine collapse in the entorhinal cortex as a hidden driver of Alzheimer's memory loss — and shows that the Parkinson's drug Levodopa can restore cognitive function in mice.
New Drug Target EPAC2 Reverses Fragile X Syndrome Symptoms in Mice
UCLA researchers found that blocking the overactive synaptic protein EPAC2 corrected brain circuit activity and reversed core behavioral symptoms in a mouse model of Fragile X syndrome.
Neural Switch for Recent Memory Retrieval Discovered
A newly identified neural circuit between the medial septum and medial entorhinal cortex actively selects recent memories over past ones, offering insights into dementia and cognitive flexibility.
Cooperation Evolves Naturally When We Recognize Others, Study Finds
New research overturns 75 years of game theory; cooperation emerges spontaneously when individuals can recognize and remember past interactions.
Brains and AI Show Similar Patterns When Processing Sentence Constructions
EEG study finds that human brains and artificial neural networks represent linguistic constructions in strikingly similar ways, supporting a shared 'Platonic' representational space.
New algorithm scales spiking neural networks to thousands of GPUs
Scientists developed a method to build brain-like spiking neural networks on up to thousands of GPUs, enabling more realistic simulations of cortical circuits.
