... with Lucifer Yellow. These neurons were then studied intracellularly and extracellularly to determine whether they suppressed the stretch-activated responses of thoracic stretch receptors. Intracellular injection of depolarizing currents into these three putative accessory neurons revealed that only neuron #3...

... the muscle fibres. Lucifer Yellow was injected ionophoretically into single muscle fibres under normal artificial sea water (ASW) and under various concentrations of calcium in ASW. Under ASW, 44 % of muscle fibres examined were dye-coupled, 82 % were coupled under calcium-free sea water and 67 % were...

..., Lymnaea stagnalis L., and tested for tracer coupling with Lucifer Yellow CH and biocytin. The cells examined were the strongly electrically coupled neurones, visceral dorsal 1 (VD1) and right parietal dorsal 2 (RPD2) ( Boer et al . 1979 ; Benjamin and Pilkington, 1986 ), and the weakly coupled neurones...

...W. J. Heitler; K. Fraser ABSTRACT A very useful technique to emerge in recent years in the field of neural circuit analysis is in situ dye-visualization and photoinactivation using Lucifer Yellow ( Stewart, 1978 ). This allows direct anatomical identification of neurones during an experiment...

... ). In such studies it can also be useful to remove only a part of a cell, such as a segment of its dendritic tree or axon. This can be done by filling the cell with the fluorescent dye Lucifer Yellow (LY) and irradiating the particular segment to be removed ( Jacobs & Miller, 1985 ). However, for behavioural...

...A. Büschges; U. T. Koch; G. Breutel ABSTRACT The use of fluorescent dyes for staining neurones has become very common since the introduction of Lucifer Yellow ( Stewart, 1978 ) because it permits high-luminance stainings, for detailed structural analysis, with a minimum of filling time. Lucifer...

... K + . Identification of recorded cells by ionophoretic injection of Lucifer Yellow showed that both major cell types of the epithelium (goblet and columnar cells) had similar control values of V b and (K + ) i and responded similarly to Ba 2+ , suggesting the presence of effective chemical...

... following iontophoretic injection of Lucifer Yellow. Freeze-etch electron microscopy revealed numerous gap-junction-like particles in CA cell plasma membranes. The spread of ionic current from cell to cell was demonstrated by injecting current pulses into one cell and recording electrotonic potentials from...
