Cortical state and attention

KD Harris, A Thiele - Nature reviews neuroscience, 2011 - nature.com
The brain continuously adapts its processing machinery to behavioural demands. To
achieve this, it rapidly modulates the operating mode of cortical circuits, controlling the way …

Laminar structure of spontaneous and sensory-evoked population activity in auditory cortex

S Sakata, KD Harris - Neuron, 2009 - cell.com
Spontaneous activity plays an important role in the function of neural circuits. Although many
similarities between spontaneous and sensory-evoked neocortical activity have been …

Cortical state determines global variability and correlations in visual cortex

ML Schölvinck, AB Saleem, A Benucci… - Journal of …, 2015 - Soc Neuroscience
The response of neurons in sensory cortex to repeated stimulus presentations is highly
variable. To investigate the nature of this variability, we compared the spike activity of …

The modulation of neural gain facilitates a transition between functional segregation and integration in the brain

JM Shine, MJ Aburn, M Breakspear, RA Poldrack - Elife, 2018 - elifesciences.org
Cognitive function relies on a dynamic, context-sensitive balance between functional
integration and segregation in the brain. Previous work has proposed that this balance is …

Can you hear me now? Musical training shapes functional brain networks for selective auditory attention and hearing speech in noise

DL Strait, N Kraus - Frontiers in psychology, 2011 - frontiersin.org
Even in the quietest of rooms, our senses are perpetually inundated by a barrage of sounds,
requiring the auditory system to adapt to a variety of listening conditions in order to extract …

UP-DOWN cortical dynamics reflect state transitions in a bistable network

D Jercog, A Roxin, P Bartho, A Luczak, A Compte… - Elife, 2017 - elifesciences.org
In the idling brain, neuronal circuits transition between periods of sustained firing (UP state)
and quiescence (DOWN state), a pattern the mechanisms of which remain unclear. Here we …

Neural population coding: combining insights from microscopic and mass signals

S Panzeri, JH Macke, J Gross, C Kayser - Trends in cognitive sciences, 2015 - cell.com
Behavior relies on the distributed and coordinated activity of neural populations. Population
activity can be measured using multi-neuron recordings and neuroimaging. Neural …

History-dependent variability in population dynamics during evidence accumulation in cortex

AS Morcos, CD Harvey - Nature neuroscience, 2016 - nature.com
We studied how the posterior parietal cortex combines new information with ongoing activity
dynamics as mice accumulate evidence during a virtual navigation task. Using new methods …

NREM sleep in the rodent neocortex and hippocampus reflects excitable dynamics

D Levenstein, G Buzsáki, J Rinzel - Nature communications, 2019 - nature.com
During non-rapid eye movement (NREM) sleep, neuronal populations in the mammalian
forebrain alternate between periods of spiking and inactivity. Termed the slow oscillation in …
