Researchers found how brains turn time-based signals into stable memories using combined short- and long-term synaptic changes.
Researchers at Tianjin University and international collaborators have identified a brain mechanism that converts sequences of neural activity over time into spatial patterns, enabling efficient information processing and storage.
The study, published in PNAS, shows that long-term and short-term synaptic changes work together to transform dynamic inputs—like a melody—into stable representations, enhancing memory and noise resistance without enlarging neural networks.
Supported by computational models and electrophysiological data from mouse and human neocortices, the findings reveal a "collaboration code" for temporal processing, offering insights for developing more efficient, interpretable artificial intelligence systems.
Los investigadores encontraron cómo los cerebros convierten señales basadas en el tiempo en recuerdos estables usando cambios sinápticos combinados a corto y largo plazo.
