Optical approaches to investigate cerebral function and metabolism have long been applied
in invasive studies. From the neuron cultured in vitro to the exposed cortex in the human …

Since optical imaging (OI) of intrinsic signals was first developed in the 1980s, significant
advances have been made regarding our understanding of the origins of the recorded …

Recent advances in brain imaging techniques, including functional magnetic resonance
imaging (fMRI), offer great promise for noninvasive map** of brain function. However, the …

To address several fundamental questions regarding how multiwhisker tactile stimuli are
integrated and processed by the trigeminal somatosensory system, a novel behavioral task …

Population activity in the cortex is poorly understood. In this report we use voltage-sensitive
dye imaging to examine the spatiotemporal patterns of a 7–10 Hz oscillation in neocortical …

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 …

Recently, the study of sensory cortex has focused on the context-dependent evolution of
receptive fields and cortical maps over millisecond to second timescales. This article reviews …

The exquisite modular anatomy of the rat somatosensory system makes it an excellent
model to test the potential coding strategies used to discriminate the location of a tactile …

Shared anatomical and physiological features of primary, secondary, tertiary, polysensory,
and associational neocortical areas are used to formulate a novel extended hypothesis of …

Optical imaging of intrinsic cortical activity was used to study the somatotopic map and the
representation of pressure, flutter, and vibration in area 3b of the squirrel monkey (Saimiri …
