Selective inhibition of the phospholipase C pathway blocks one light-activated current component in Limulus photoreceptor
Zeitschrift für vergleichende Physiologie - Tập 177 - Trang 601-610 - 1995
K. Contzen, K. -H. Richter, K. Nagy
Light-activated receptor currents were measured in Limulus ventral nerve photoreceptors by a two electrode voltage clamp. Short flashes stimulate three different current components (C1, C2, C3). Currents were measured before and after injection of neomycin, heparin and BAPTA. These substances inhibit the inositol phosphate pathway at different stages. Each substance selectively blocked the C2 comp...... hiện toàn bộ
Walking on a ‘peg leg’: extensor muscle activities and sensory feedback after distal leg denervation in cockroaches
Zeitschrift für vergleichende Physiologie - Tập 190 - Trang 217-231 - 2004
J. A. Noah, L. Quimby, S. F. Frazier, S. N. Zill
Previous studies in insects demonstrated that leg coordination changes following complete ablation of distal limb segments. However, normal coordination was restored when small ‘peg leg’ prostheses were attached to leg stumps to permit substrate contact. We have adapted this paradigm to preserve appropriate leg mass and inertia by severing all nerves and muscle tendons in the femur of the cockroac...... hiện toàn bộ

Active and passive axonal propagation of non-spike signals in the retina ofCalliphora
Zeitschrift für vergleichende Physiologie - Tập 85 - Trang 89-104 - 1973
F. Zettler, M. Järvilehto
The dipteran photoreceptors of type R1–6 and the monopolar neurons of type L1–2 have been investigated. The light-induced intracellular potentials within a single cell type vary according to the part of the cell from which they are recorded. Current passed artificially through the cell membrane could influence these light-induced potentials. The nature of the dependence of the potentials upon such...... hiện toàn bộ

Untersuchungen zur vergleichenden Physiologie der Lichtempfindlichkeit geblendeter Fische
Zeitschrift für vergleichende Physiologie - Tập 49 - Trang 58-90 - 1964
Ingrid de la Motte
Die Lichtempfindlichkeit von geblendeten Süßwasserfischen aus 16 verschiedenen Familien wurde untersucht. Dabei wurden Dressurreaktionen (Licht-Futter-Dressur) sowie spontane Reaktionen auf Belichtung ausgewertet. Bei allen Fischen (s. Tabelle S. 67) löste eine Belichtung des Kopfes Reaktionen aus. Bei Aalen und beim Lungenfisch wurde darüber hinaus eine Lichtempfindlichkeit von Rumpf- und Schwanz...... hiện toàn bộ
Elektrische Antworten im Vorderhirn von Lampetra fluviatilis (L.) bei Reizung des Nervus olfactorius
Zeitschrift für vergleichende Physiologie - Tập 75 - Trang 69-85 - 1971
Peter Bruckmoser
Am curarisierten Flußneunauge wurden elektrische Antworten im Bulbus olfactorius, im Lobus olfaotorius und im Primordium hippocampi nach elektrischer Reizung des Nervus olfactorius registriert. Die Antwort an der Oberfläche des Bulbus olfactorius besteht aus einem viergipfeligen, im wesentlichen negativen Potential, dessen erste Komponente das (präsynaptische) Potential des Nervus olfactorius dars...... hiện toàn bộ
The oscar, Astronotus ocellatus, detects and discriminates dipole stimuli with the lateral line system
Zeitschrift für vergleichende Physiologie - Tập 197 - Trang 959-968 - 2011
Joachim Mogdans, Ines E. Nauroth
We studied the role of the lateral line system for detection and discrimination of dipole stimuli in the oscar, Astronotus ocellatus (Family Cichlidae), and determined detection thresholds in still water and frequency discrimination capabilities in still and turbulent water. Average detection threshold of six animals for a 100-Hz dipole stimulus was 0.0059 μm peak-to-peak water displacement at the...... hiện toàn bộ
