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 …

Functional magnetic resonance imaging (fMRI) is currently the mainstay of neuroimaging in
cognitive neuroscience. Advances in scanner technology, image acquisition protocols …

Recent advances in multi-electrode array technology have made it possible to monitor large
neuronal ensembles at cellular resolution in animal models. In humans, however, current …

We present a first-draft digital reconstruction of the microcircuitry of somatosensory cortex of
juvenile rat. The reconstruction uses cellular and synaptic organizing principles to …

Background Neuronal networks in the brain include glutamatergic principal neurons and
GABAergic interneurons (GABA, γ-aminobutyric acid). The latter may be a minority cell type …

Mammals adapt to a rapidly changing world because of the sophisticated cognitive functions
that are supported by the neocortex. The neocortex, which forms almost 80% of the human …

Synchronous rhythms represent a core mechanism for sculpting temporal coordination of
neural activity in the brain-wide network. This review focuses on oscillations in the cerebral …

The mammalian visual system is endowed with a nearly infinite capacity for the recognition
of patterns and objects. To have acquired this capability the visual system must have solved …

Through a widespread efferent projection system, the locus coeruleus–noradrenergic
system supplies norepinephrine throughout the central nervous system. Initial studies …

Most of our knowledge about the functional organization of neuronal systems is based on
the analysis of the firing patterns of individual neurons that have been recorded one by one …
