Beitrag zum Problem der heterosynaptischen Facilitation in Aplysia californica
(Springer-Verlag, 1967-12)
1. Heterosynaptic facilitation (H.S.F.) of single neurons in the central nervous system of Aplysia can be repeated virtually indefinitely, provided sufficient time is allowed for recovery between the trials.
Does schooling reduce fast-start response latencies in teleosts?
(Elsevier, 1980)
1. 1. Response latencies, denned as the time between a d.c. electric shock and initiation of a fast-start (startle response) were measured for eight species of teleosts.2. 2. Fast-start response latencies varied from 10 ...
Microelectrode analysis of light responses in the brain of the cricket ( Gryllus domesticus ) This research was done during the tenure of a U.S.P.H.S., N.I.M.H. postdoctoral fellowship (H.D.) and was supported by N.S.F. grant GB-1711 to S. S. Fox. For technical assistance we are grateful to Miss Bonnie Cross and Miss Joanna Wirble.
(Wiley Subscription Services, Inc., A Wiley Company, 1966-08)
Electrical activity in response to light stimuli was recorded from the brain of the cricket ( Gryllus domesticus ) using stainless steel microelectrodes. Four basic types of elements were observed as follows: (1) units ...
Histamine and cis-urocanic acid augment tumor necrosis factor-alpha mediated induction of keratinocyte intercellular adhesion molecule-1 expression
(Wiley Subscription Services, Inc., A Wiley Company, 1993-08)
Early cellular and molecular events in inflamed skin include the active participation of epidermal keratinocytes (KCs) and dermal mast cells which can produce diffusible mediators such as tumor necrosis factor-alpha (TNF-Α), ...
Potassium-induced vascular relaxation in two kidney-one clip, renal hypertensive rats
(Springer-Verlag, 1983-01)
This study was designed to characterize potassium-induced relaxation in vascular smooth muscle in two kidneyone clip (2K-1C), renal hypertensive rats. Potassium-induced relaxation was evaluated in the isolated tail artery ...
Comparative biochemical studies of osmo-regulation in sipuncula--I. Steady-state characteristics of two sipunculids in full-strength sea water
(Elsevier, 1974)
1. 1. Chemical analyses are reported for centrifuged coelomic fluid, body wall, retractor muscles and coelomocytes of the Sipunculids Themiste dyscritum and Phascolopsis gouldi acclimated to full-strength sea water.2. 2. ...
Osmoregulation in Blaberus craniifer after parenteral injections of NaCl solutions
(Elsevier, 1977)
1. 1. After injection of NaCl into the abdominal hemocoel of Blaberus craniifer, the osmotic concentration of antennal hemolymph peaked at 1.25hr and returned to pre-injection concentration by 21 hr. The mean plasma clearance ...
The temperature dependence of myosin-adenosinetriphosphatase and alkaline phosphatase in lizards,
(Elsevier, 1964-07)
1. 1. The temperature dependence of myosin ATP-ase and intestinal alkaline phosphatase from a variety of lizards having distinct preferred temperatures was compared.2. 2. The ATP-ase was relatively thermolabile; reductions ...
Single unit discrimination of fish odours released by char (Salmo alpinus L.) populations
(Elsevier, 1974)
1. 1. Dilute fish odours from four distinct char populations elicited differential responses from char olfactory bulb cells.2. 2. Differential sensory responses produced by odours from migratory and non-migratory populations ...
Live mass, water content, nitrogen and mineral levels in some insects from south-central lower michigan
(Elsevier, 1992-11)
1. 1. Live and dry mass, water content, nitrogen, sodium, potassium, magnesium, calcium and total iron concentrations are reported (or are available from the authors or the Faculty/Staff Collection of The University of ...
