Perception and propagation of activity through the cortical hierarchy is determined by neural variability
The brains of higher organisms are composed of anatomically and functionally distinct
regions performing specialised tasks; but regions do not operate in isolation. Orchestration …

The relation of ongoing brain activity, evoked neural responses, and cognition
Ongoing brain activity has been observed since the earliest neurophysiological recordings
and is found over a wide range of temporal and spatial scales. It is characterized by …

Task-evoked activity quenches neural correlations and variability across cortical areas
Many large-scale functional connectivity studies have emphasized the importance of
communication through increased inter-region correlations during task states. In contrast …

A dynamical systems framework to uncover the drivers of large-scale cortical activity
ABSTRACT A fundamental challenge in neuroscience is to uncover the principles governing
complex interactions between the brain and its external environment. Over the past few …

Learning and attention reveal a general relationship between neuronal variability and perception
The trial-to-trial response variability that is shared between pairs of neurons (termed spike
count correlations or r SC) has been the subject of many recent studies largely because it …

Feedforward and feedback interactions between visual cortical areas use different population activity patterns
Brain function relies on the coordination of activity across multiple, recurrently connected
brain areas. For instance, sensory information encoded in early sensory areas is relayed to …

Coupled oscillations orchestrate selective information transmission in visual cortex
Performing visually guided behavior involves flexible routing of sensory information towards
associative areas. We hypothesize that in visual cortical areas, this routing is shaped by a …

Distinct brain-wide presynaptic networks underlie the functional identity of individual cortical neurons
Neuronal connections provide the scaffolding for neuronal function. Revealing the
connectivity of functionally identified individual neurons is necessary to understand how …

Similarity in evoked responses does not imply similarity in macroscopic network states across tasks
There is an ongoing debate as to whether cognitive processes arise from a group of
functionally specialized brain modules (modularism) or as the result of distributed nonlinear …
