Yale Team Uncovers Origin of Gamma Brain Waves in Thalamus-Cortex Interaction

Yale neuroscientists have identified the precise origin of gamma brain waves, tracing them to interactions between the thalamus and cortex. The breakthrough could reshape understanding of neurological disorders and cognitive processing.

A Century-Old Neuroscience Puzzle Solved

For over a hundred years, scientists have been tracking the brain’s rhythmic electrical patterns without fully understanding where they come from or exactly what they do. Now, according to research published in Nature, Yale University neuroscientists have cracked one of neuroscience’s enduring mysteries by pinpointing the origin of gamma waves and linking them directly to behavior.

Study Reveals AI Model Performance Decline from Low-Quality Training Data

Researchers have quantified how training AI models on low-quality web data leads to performance degradation. The study shows significant declines in reasoning and memory capabilities when models are exposed to “junk” content, raising concerns about current data collection practices.

The “Brain Rot” Hypothesis for AI Systems

Artificial intelligence models may be suffering from a form of digital cognitive decline when trained on low-quality web content, according to reports from a multi-university research team. Sources indicate that what researchers are calling “LLM brain rot hypothesis” suggests continual pre-training on trivial online text induces lasting performance degradation in large language models, mirroring effects observed in humans consuming large volumes of unchallenging digital content.
