... formation in snails and reduced the duration of the effects of the severe traumatic stressor on learning and memory. Neither WIN 55 nor AM 251 altered normal homeostatic aerial respiratory behaviour elicited in hypoxic conditions. Our results suggest that putative cannabinoid receptors mediate stressful...

... (50–100 μmol l –1 ) on aerial respiratory behaviour, associative learning,and its subsequent consolidation into long-term memory (LTM). A 3-neuron network whose sufficiency and necessity have been demonstrated drives aerial respiratory behaviour in Lymnaea . In the presence of 100 μmol l –1 H 2 S...

...Ken Lukowiak; Erika Ringseis; Gaynor Spencer; Wic Wildering; Naweed Syed ABSTRACT In this study, we operantly conditioned the aerial respiratory behaviour of the freshwater snail Lymnaea stagnalis . Aerial respiration in Lymnaea stagnalis is accomplished by the spontaneous opening and closing...
