Abstract
Imaging of cerebellar surface activation in vivo using voltage sensitive dyes.
Journal:Neuroscience
PubMed ID:2594193
'The understanding of the information processing performed by complex neuronal networks in the central nervous system will require techniques permitting the simultaneous monitoring of the electrical activity of neuronal ensembles. Voltage sensitive dyes offer the potential for non-invasive optical monitoring of the activity in large populations of neurons. In this
Dynamic origin of spatially discordant alternans in cardiac tissue.
Journal:Biophys J
PubMed ID:17071663
'Alternans, a condition in which there is a beat-to-beat alternation in the electromechanical response of a periodically stimulated cardiac cell, has been linked to the genesis of life-threatening ventricular arrhythmias. Optical mapping of membrane voltage (V(m)) and intracellular calcium (Ca(i)) on the surface of animal hearts reveals complex spatial patterns
Fluorescence imaging of local membrane electric fields during the excitation of single neurons in culture.
Journal:Biophys J
PubMed ID:8527643
'The spatial distribution of depolarized patches of membrane during the excitation of single neurons in culture has been recorded with a high spatial resolution (1 micron2/pixel) imaging system based on a liquid-nitrogen-cooled astronomical camera mounted on an inverted microscope. Images were captured from rat nodose neurons stained with the voltage-sensitive
Voltage-sensitive dye recording of action potentials and synaptic potentials from sympathetic microcultures.
Journal:Biophys J
PubMed ID:1681956
'Given the appropriate multicell electrophysiological techniques, small networks of cultured neurons (microcultures) are well suited to long-term studies of synaptic plasticity. To this end, we have developed an apparatus for optical recording from cultured vertebrate neurons using voltage-sensitive fluorescent dyes (Chien, C.-B., and J. Pine. 1991. J. Neurosci. Methods. 38:93-105).
Charge translocation by the Na,K-pump: I. Kinetics of local field changes studied by time-resolved fluorescence measurements.
Journal:J Membr Biol
PubMed ID:1652643
'Membrane fragments containing a high density of Na,K-ATPase can be noncovalently labeled with amphiphilic styryl dyes (e.g., RH 421). Phosphorylation of the Na,K-ATPase by ATP in the presence of Na+ and in the absence of K+ leads to a large increase of the fluorescence of RH 421 (up to 100%).
