Correlations and neuronal population information

A Kohn, R Coen-Cagli, I Kanitscheider… - Annual review of …, 2016 - annualreviews.org
Brain function involves the activity of neuronal populations. Much recent effort has been

Beyond task response–pre-stimulus activity modulates contents of consciousness

G Northoff, F Zilio, J Zhang - Physics of life reviews, 2024 - Elsevier
The current discussion on the neural correlates of the contents of consciousness (NCCc)
focuses mainly on the post-stimulus period of task-related activity. This neglects the …

Reduced neural feedback signaling despite robust neuron and gamma auditory responses during human sleep

H Hayat, A Marmelshtein, AJ Krom, Y Sela… - Nature …, 2022 - nature.com
During sleep, sensory stimuli rarely trigger a behavioral response or conscious perception.
However, it remains unclear whether sleep inhibits specific aspects of sensory processing …

Behavior needs neural variability

L Waschke, NA Kloosterman, J Obleser, DD Garrett - Neuron, 2021 - cell.com
Human and non-human animal behavior is highly malleable and adapts successfully to
internal and external demands. Such behavioral success stands in striking contrast to the …

Neural correlates of sparse coding and dimensionality reduction

M Beyeler, EL Rounds, KD Carlson, N Dutt… - PLoS computational …, 2019 - journals.plos.org
Supported by recent computational studies, there is increasing evidence that a wide range
of neuronal responses can be understood as an emergent property of nonnegative sparse …

Maximizing sensory dynamic range by tuning the cortical state to criticality

SH Gautam, TT Hoang, K McClanahan… - PLoS computational …, 2015 - journals.plos.org
Modulation of interactions among neurons can manifest as dramatic changes in the state of
population dynamics in cerebral cortex. How such transitions in cortical state impact the …

Origin of information-limiting noise correlations

I Kanitscheider, R Coen-Cagli, A Pouget - Proceedings of the National …, 2015 - pnas.org
The ability to discriminate between similar sensory stimuli relies on the amount of
information encoded in sensory neuronal populations. Such information can be substantially …

Local cortical desynchronization and pupil-linked arousal differentially shape brain states for optimal sensory performance

L Waschke, S Tune, J Obleser - Elife, 2019 - elifesciences.org
Instantaneous brain states have consequences for our sensation, perception, and
behaviour. Fluctuations in arousal and neural desynchronization likely pose perceptually …

Spontaneous cortical activity is transiently poised close to criticality

G Hahn, A Ponce-Alvarez, C Monier… - PLoS computational …, 2017 - journals.plos.org
Brain activity displays a large repertoire of dynamics across the sleep-wake cycle and even
during anesthesia. It was suggested that criticality could serve as a unifying principle …

States and traits of neural irregularity in the age-varying human brain

L Waschke, M Wöstmann, J Obleser - Scientific reports, 2017 - nature.com
Sensory representations, and thus human percepts, of the physical world are susceptible to
fluctuations in brain state or “neural irregularity”. Furthermore, aging brains display altered …
