The Correlation Between Electrical Pulses and Light Flashes in a Proportional Counter.
A proportional counter is a device used to measure the energy spectra of charged particles and photons. The charged particle ionizes the gas molecules along its path. In the presence of a strong electric field, the electrons and ions are swept toward the collecting electrodes. The electric field …

The effects of the tubulin-binding drug, colchicine, on the electrophysiological aspects of phototransduction in toad rod photoreceptors
… and altered the kinetics of voltage responses to light flashes. These effects persisted during blockade of rod inner segment conductances, but colchicine's effects during illumination were minimal. The presence of colchicine, however, did not block rod depolarization evoked by increasing …

Cortical Pyramidal Neuron Subtype Classification and Visual Response Diversity
… responses of identified neurons to diffuse light flashes. Visual responses consist of a smooth early response and a more dominant and fluctuating late response. These response epochs are hypothesized to correspond to thalamic and intracortical inputs, respectively. Cluster analysis of the …

Effects of Electromagnetic Fields on the Visually Evoked Response in the Visual Cortex
… the visual cortex of cats by visual stimulation (light flashes). Surface electrodes, located at the visual cortex (and connected to a preamplifier and an oscilloscope) detectedthe evoked responses which (after being modulated by a frequency modulator) were recorded on magnetic tapes.</p> <p>From …

The Role of Calcium in Signal Transduction: Kinetics and Regulation of Intracellular Calcium During the Photomechanical Response of the Albino Rat Sphincter Pupillae Smooth Muscle
… calcium-calmodulin complexes → myosin light chain kinase → phosphorylated myosin → force. In the isolated vertebrate sphincter pupillae, the myosin phosphorylation cascade can be activated very precisely by controlled light stimuli, which result in equivalently precise …

The aqueous photochemistry of 4-chlorophenol
… being subjected to a series of microsecond white light flashes and the result of the photolysis analysed by HPLC. In aerated solution, para-benzoquinone is the main photoproduct together with smaller amounts of para-hydroquinone and 2-hydroxy-1,4-benzoquinone. The latter is found to be the …
