Noise in neural populations accounts for errors in working memory

PM Bays - Journal of Neuroscience, 2014 - Soc Neuroscience
Errors in short-term memory increase with the quantity of information stored, limiting the
complexity of cognition and behavior. In visual memory, attempts to account for errors in …

Spikes not slots: noise in neural populations limits working memory

PM Bays - Trends in cognitive sciences, 2015 - cell.com
This opinion article argues that noise (randomness) in neural activity is the limiting factor in
visual working memory (WM), determining how accurately we can maintain stable internal …

Drift in neural population activity causes working memory to deteriorate over time

S Schneegans, PM Bays - Journal of Neuroscience, 2018 - Soc Neuroscience
Short-term memories are thought to be maintained in the form of sustained spiking activity in
neural populations. Decreases in recall precision observed with increasing number of …

Stochastic sampling provides a unifying account of visual working memory limits

S Schneegans, R Taylor… - Proceedings of the …, 2020 - National Acad Sciences
Research into human working memory limits has been shaped by the competition between
different formal models, with a central point of contention being whether internal …

Error-correcting dynamics in visual working memory

MF Panichello, B DePasquale, JW Pillow… - Nature …, 2019 - nature.com
Working memory is critical to cognition, decoupling behavior from the immediate world. Yet,
it is imperfect; internal noise introduces errors into memory representations. Such errors …

A neural measure of precision in visual working memory

EF Ester, DE Anderson, JT Serences… - Journal of cognitive …, 2013 - direct.mit.edu
Recent studies suggest that the temporary storage of visual detail in working memory is
mediated by sensory recruitment or sustained patterns of stimulus-specific activation within …

Ghosts in the machine: memory interference from the previous trial

C Papadimitriou, A Ferdoash… - Journal of …, 2015 - journals.physiology.org
Previous memoranda can interfere with the memorization or storage of new information, a
concept known as proactive interference. Studies of proactive interference typically use …

Adaptive allocation of human visual working memory capacity during statistical and categorical learning

CJ Bates, RA Lerch, CR Sims, RA Jacobs - Journal of vision, 2019 - jov.arvojournals.org
Human brains are finite, and thus have bounded capacity. An efficient strategy for a capacity-
limited agent is to continuously adapt by dynamically reallocating capacity in a task …

[HTML][HTML] Oscillatory brain state predicts variability in working memory

NE Myers, MG Stokes, L Walther… - Journal of …, 2014 - Soc Neuroscience
Our capacity to remember and manipulate objects in working memory (WM) is severely
limited. However, this capacity limitation is unlikely to be fixed because behavioral models …

Dynamic updating of working memory resources for visual objects

N Gorgoraptis, RFG Catalao, PM Bays… - Journal of …, 2011 - Soc Neuroscience
Recent neurophysiological and imaging studies have investigated how neural
representations underlying working memory (WM) are dynamically updated for objects …
