Schizophrenia is a complex psychiatric disorder exhibiting alterations in spontaneous and
task-related cerebral activity whose relation (termed “state dependence”) remains unclear …

Within the broad field of human perception lies the category of stimulus-independent
perceptions, which draws together experiences such as hallucinations, mental imagery and …

During music listening, humans routinely acquire the regularities of the acoustic sequences
and use them to anticipate and interpret the ongoing melody. Specifically, in line with this …

Controlling gain of cortical activity is essential to modulate weights between internal ongoing
communication and external sensory drive. Here, we show that serotonergic input has …

Visual responses are extensively shaped by internal factors. This effect is drastic in the
primary visual cortex (V1), where locomotion profoundly increases visually-evoked …

The relation between spontaneous and stimulated global brain activity is a fundamental
problem in the understanding of brain functions. This question is investigated both …

During complex tasks, patterns of functional connectivity differ from those in the resting state.
However, what accounts for such differences remains unclear. Brain activity during a task …

What is the effect of activating a single modulatory neuronal receptor type on entire brain
network dynamics? Can such effect be isolated at all? These are important questions …

Neural systems can be modeled as complex networks in which neural elements are
represented as nodes linked to one another through structural or functional connections …

The awake cortex is characterized by a higher level of ongoing spontaneous activity, but it
has a better detectability of weak sensory inputs than the anesthetized cortex. However, the …
