Background Although it is well recognized that autism is associated with altered patterns of
over-and under-connectivity, specifics are still a matter of debate. Little has been done so far …

Despite the several-thousand-fold increase of brain volume during the course of mammalian
evolution, the hierarchy of brain oscillations remains remarkably preserved, allowing for …

Spatial working memory, the caching of behaviourally relevant spatial cues on a timescale of
seconds, is a fundamental constituent of cognition. Although the prefrontal cortex and …

Gamma rhythms are commonly observed in many brain regions during both waking and
sleep states, yet their functions and mechanisms remain a matter of debate. Here we review …

Summary Ultra-slow,∼ 0.1-Hz variations in the oxygenation level of brain blood are widely
used as an fMRI-based surrogate of" resting-state" neuronal activity. The temporal …

A central motif in neuronal networks is convergence, linking several input neurons to one
target neuron. In visual cortex, convergence renders target neurons responsive to complex …

Converging evidence from electrophysiological, physiological and anatomical studies
suggests that abnormalities in the synchronized oscillatory activity of neurons may have a …

Neurons in the brain communicate by short electrical pulses, the so-called action potentials
or spikes. How can we understand the process of spike generation? How can we …

The emergence of a unified cognitive moment relies on the coordination of scattered
mosaics of functionally specialized brain regions. Here we review the mechanisms of large …

Intrinsic coupling constitutes a key feature of ongoing brain activity, which exhibits rich
spatiotemporal patterning and contains information that influences cognitive processing. We …
