Neuromodulation of attention
Attention is critical to high-level cognition and attention deficits are a hallmark of neurologic
and neuropsychiatric disorders. Although years of research indicates that distinct …

Correlations and neuronal population information
Brain function involves the activity of neuronal populations. Much recent effort has been
devoted to measuring the activity of neuronal populations in different parts of the brain under …

Alpha and gamma oscillations characterize feedback and feedforward processing in monkey visual cortex
Cognitive functions rely on the coordinated activity of neurons in many brain regions, but the
interactions between cortical areas are not yet well understood. Here we investigated …

[HTML][HTML] Arousal and locomotion make distinct contributions to cortical activity patterns and visual encoding
Spontaneous and sensory-evoked cortical activity is highly state-dependent, yet relatively
little is known about transitions between distinct waking states. Patterns of activity in mouse …

The mechanics of state-dependent neural correlations
Simultaneous recordings from large neural populations are becoming increasingly common.
An important feature of population activity is the trial-to-trial correlated fluctuation of spike …

Top-down control of visual attention by the prefrontal cortex. Functional specialization and long-range interactions
The ability to select information that is relevant to current behavioral goals is the hallmark of
voluntary attention and an essential part of our cognition. Attention tasks are a prime …

Suppressing feedback signals to visual cortex abolishes attentional modulation
SR Debes, V Dragoi - Science, 2023 - science.org
Attention improves perception by enhancing the neural encoding of sensory information. A
long-standing hypothesis is that cortical feedback projections carry top-down signals to …

Priority coding in the visual system
Although we are continuously bombarded with visual input, only a fraction of incoming visual
events is perceived, remembered or acted on. The neural underpinnings of various forms of …

State dependence of noise correlations in macaque primary visual cortex
Shared, trial-to-trial variability in neuronal populations has a strong impact on the accuracy
of information processing in the brain. Estimates of the level of such noise correlations are …
