Electrode recordings and imaging studies have revealed that localized visual stimuli elicit
waves of activity that travel across primary visual cortex. Traveling waves are present also …

The development of voltage-sensitive dyes (VSD) and fast optical imaging techniques have
brought us a new tool for examining spatiotemporal patterns of population neuronal activity …

Although spiral waves are ubiquitous features of nature and have been observed in many
biological systems, their existence and potential function in mammalian cerebral cortex …

In this review, we present the voltage-sensitive dye imaging (VSDI) method. The possibility
offered for in vivo (and in vitro) brain imaging is unprecedented in terms of spatial and …

The visual cortex represents stimuli through the activity of neuronal populations. We
measured the evolution of this activity in space and time by imaging voltage-sensitive dyes …

These are exciting times for the field of optical imaging of brain function. Rapid
developments in theory and technology continue to considerably advance understanding of …

The transfer of visual information from the primary visual cortex (V1) to higher order visual
cortices is an essential step in visual processing. However, the dynamics of activation of …

Research based on functional imaging and neuronal recordings in the barrel cortex
subdivision of primary somatosensory cortex (SI) of the adult rat has revealed novel aspects …

Neurons in the primary visual cortex receive subliminal information originating from the
periphery of their receptive fields (RF) through a variety of cortical connections. In the cat …

Sensory responses in neocortex are strongly modulated by changes in brain state, such as
those observed between sleep stages or attentional levels. However, the specific effects of …
