Cortical activity modulation of language processing by dynamic optimization of task complexity and functional restrictions
Language, regarded as a hierarchical cognitive code activated by functional operational modes of the brain by most neuropsychologists, is characterized by increased cognitive load in successively h…

Modularity maps reveal community structure in the resting human brain
The brain is a complex network of interconnecting neurons that combines regional specificity with distributed processing. Recent advances in the field of network theory have facilitated ground-brea…

Cerebral and Spinal Modulation of Pain by Emotions
Emotions have powerful effects on pain perception. However, the brain mechanisms underlying these effects remain largely unknown. In this study, we combined functional cerebral imaging with psychop…

Endogenous human brain dynamics recover slowly following cognitive effort
In functional magnetic resonance imaging, the brain’s response to experimental cognitive tasks is usually assumed to be independent of endogenous oscillations. To test this assumption, we measured …

‘Magnetized’ brains are slower: The cognitive effects of fMRI
MRI is generally thought to have no impact on cognition. Although safety experiments have shown that MRI is not harmful, its finer effects have not been investigated. Because we repeatedly observed…

Music in the first days of life
In adults, specific neural systems with right-hemispheric weighting are necessary to process pitch, melody and harmony, as well as structure and meaning emerging from musical sequences. To which ex…

Accumulation of Neural Activity in the Posterior Insula Encodes the Passage of Time
The experience of time, i.e. the estimation of duration, is fundamental for perception and behavior and, therefore, essential for the survival of the individual organism. Over the last decades, neu…

Developing Language Abilities by a Non-verbal Training : A fMRI Study
The language ability is a critical aspect of experimental design in functional imaging studies. Today, it is commonly accepted that the brain structures underlying the language are more distributed…
