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.
Thermal adjustments in cardiac and skeletal muscles of lizards
(Springer-Verlag, 1969-03)
1. Isometric twitch tension development was measured over a wide range of temperatures in skeletal and cardiac (ventricular) muscles from diverse Australian lizards representing several families and including both diurnal ...
The effect of limbic damage on the retention and performance of a runway response
(Elsevier, 1966-07)
Rats were trained to run a linear runway while hungry for food. Then they were tested for retention, continued performance levels, and extinction after recovery from bilateral damage of the hippocampus, the septal area, ...
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 ...
The effect of brainstem transection on blood pressure in the dog
(Elsevier, 1969-03-01)
Blood pressure was compared before and after midpontine pretrigeminal brainstem transection in the dog. Statistically significant decreases in blood pressure were observed 1/2, 1, and 1-1/2 hours after brainstem transection. ...
Biosynthesis of alkyl-ether containing lipid from dihydroxyacetone phosphate
(Elsevier, 1969-10-22)
A lipid, stable to alkaline methanolysis, is formed when liver mitochondria or brain microsomes are incubated with dihydroxyacetone phosphate, long chain alcohol, ATP, CoA, NaF and Mg++. The lipid has been identified as ...
The subocular shelf of fishes This study has been made possible by a research grant from the National Science Foundation (G-6368).

No Abstract.
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 ...
The chemical synthesis of 2-keto-3-deoxy-octonate and its cleavage by a specific aldolase
(Elsevier, 1963-05-22)
We have previously reported (Heath and Ghalambor, 1963) the occurrence of 2-keto-3-deoxy-octonate (KDO) as a glycosidically-bound constituent of cell wall lipopolysaccharide (LPS) of 0111-B4 and the enzymatic synthesis ...
Synthesis and maturation of phage P22 DNA : II. Properties of temperature-sensitive phage mutants defective in DNA metabolism
(Elsevier, 1968-06-28)
Three temperature-sensitive mutants of phage P22 have been isolated which are defective in phage DNA metabolism. After infection at restrictive temperature, one mutant (ts 12.1) fails to synthesize measurable quantities ...
