Cross-Subject EEG Vowel Decoding: A Reality Check
A rigorous benchmark finds limited evidence for cross-subject EEG vowel decoding, with best model near chance and participant effects dominating.
Forgetting the Right Things: How Memory Consolidation Balances Detail and Generalization
A new computational model reveals that memory consolidation works best at an intermediate granularity—storing enough detail to distinguish important situations but not so much that generalization suffers.
Oscillatory Hierarchical Reservoirs: A New Model for Human-Like Rhythm Perception
A new computational model with coupled neural oscillators across four layers mimics human anticipation of complex rhythms, offering insights into how brains predict musical beats.
