Researchers find that when working memory gets overburdened, dialogue between three brain regions breaks down. The discovery provides new support for a larger concept about how the brain works.
To Remember, the Brain Must Actively Forget | Quanta Magazine
Researchers find evidence that neural systems actively remove memories, suggesting that forgetting may be the default mode of the brain.
Heavy multitaskers have reduced memory
People who frequently engage with multiple types of media at once performed worse on simple memory tasks, according to the last decade of research. However, it’s still too soon to determine cause and effect, says psychology Professor Anthony Wagner.

Random noise promotes slow heterogeneous synaptic dynamics important for robust working memory computation
Recurrent neural networks (RNNs) based on model neurons that communicate via continuous signals have been widely used to study how cortical neural circuits perform cognitive tasks. Training such networks to perform tasks that require information maintenance over a brief period (i.e., working memory tasks) remains a challenge. Inspired by the robust information maintenance observed in higher cortical areas such as the prefrontal cortex, despite substantial inherent noise, we investigated the effects of random noise on RNNs across different cognitive functions, including working memory. Our findings reveal that random noise not only speeds up training but also enhances the stability and performance of RNNs on working memory tasks. Importantly, this robust working memory performance induced by random noise during training is attributed to an increase in synaptic decay time constants of inhibitory units, resulting in slower decay of stimulus-specific activity critical for memory maintenance. Our study reveals the critical role of noise in shaping neural dynamics and cognitive functions, suggesting that inherent variability may be a fundamental feature driving the specialization of inhibitory neurons to support stable information processing in higher cortical regions.
