Dynamic functional connectivity: promise, issues, and interpretations

RM Hutchison, T Womelsdorf, EA Allen, PA Bandettini… - Neuroimage, 2013 - Elsevier
The brain must dynamically integrate, coordinate, and respond to internal and external
stimuli across multiple time scales. Non-invasive measurements of brain activity with fMRI …

The secret life of predictive brains: what's spontaneous activity for?

G Pezzulo, M Zorzi, M Corbetta - Trends in cognitive sciences, 2021 - cell.com
Brains at rest generate dynamical activity that is highly structured in space and time. We
suggest that spontaneous activity, as in rest or dreaming, underlies top-down dynamics of …

Spontaneous behaviors drive multidimensional, brainwide activity

C Stringer, M Pachitariu, N Steinmetz, CB Reddy… - Science, 2019 - science.org
INTRODUCTION In the absence of sensory inputs, the brain produces structured patterns of
activity, which can be as large as or larger than sensory-driven activity. Ongoing activity …

Facemap: a framework for modeling neural activity based on orofacial tracking

A Syeda, L Zhong, R Tung, W Long, M Pachitariu… - Nature …, 2024 - nature.com
Recent studies in mice have shown that orofacial behaviors drive a large fraction of neural
activity across the brain. To understand the nature and function of these signals, we need …

Not so spontaneous: Multi-dimensional representations of behaviors and context in sensory areas

L Avitan, C Stringer - Neuron, 2022 - cell.com
Sensory areas are spontaneously active in the absence of sensory stimuli. This
spontaneous activity has long been studied; however, its functional role remains largely …

Normalization as a canonical neural computation

M Carandini, DJ Heeger - Nature reviews neuroscience, 2012 - nature.com
There is increasing evidence that the brain relies on a set of canonical neural computations,
repeating them across brain regions and modalities to apply similar operations to different …

Bring the noise: reconceptualizing spontaneous neural activity

LQ Uddin - Trends in Cognitive Sciences, 2020 - cell.com
Definitions of what constitutes the 'signal of interest'in neuroscience can be controversial,
due in part to continuously evolving notions regarding the significance of spontaneous …

Cellular mechanisms of brain state–dependent gain modulation in visual cortex

PO Polack, J Friedman, P Golshani - Nature neuroscience, 2013 - nature.com
Visual cortical neurons fire at higher rates to visual stimuli during locomotion than during
immobility, while maintaining orientation selectivity. The mechanisms underlying this change …

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 …

Resting‐state networks show dynamic functional connectivity in awake humans and anesthetized macaques

RM Hutchison, T Womelsdorf, JS Gati… - Human brain …, 2013 - Wiley Online Library
Characterization of large‐scale brain networks using blood‐oxygenation‐level‐dependent
functional magnetic resonance imaging is typically based on the assumption of network …
