Many plants and animals are capable of developing in a variety of ways, forming characteristics that are well adapted to the environments in which they are likely to live. In adverse circumstances, for example, small size and slow metabolism can facilitate survival, whereas larger size and more rapid metabolism have advantages for reproductive success when(More)
Three histamine H1-receptor antagonists, chlorpheniramine, diphenhydramine and tripelennamine, were tested alone or in combination with morphine, amphetamine and scopolamine on locomotor activity in mice. All three antihistaminics, at some dosage levels, enhanced morphine-induced hyperactivity, but did not change or even reduce locomotor stimulation induced(More)
Various categories of the motor behavior were recorded using a video tape in mice subjected to a 10 min activity session in a toggle-floor box after an ip administration of saline solution, d-amphetamine (2 or 4 mg/kg), morphine (10 or 20 mg/kg) or scopolamine (0.5 or 1 mg/kg). While all the three drugs enhanced horizontal activity, in particular the(More)
Acomys cahirinus is a precocial murid and a comparison of its development with altricial species of the same family, such as the rat and mouse, may shed some light on the relationship between genetic and environmental factors in the development. The use of Acomys in neurobehavioural studies and its comparison with mouse and rat may be particularly(More)
The exploratory behavior of two species of murid rodents, Acomys cahirinus and Mus musculus, was compared in four experiments: In the first, the responses of the two species to a novel arena were studied. Mus was found to take longer to enter the arena, and to spend more time in the relatively familiar or safer start box, than was Acomys. The results(More)
The effects of malnutrition on the ontogeny of reflex and electrocorticographic (ECoG) activities were studied in the progeny of mice fed with diets deficient in essential fatty acids (EFA-deprived) during the last week of pregnancy. Previous findings suggested that prenatal deficiency in essential fatty acids may result in extensive modifications of brain(More)
