The changes in heart rate and circadian cardiac rhythm of crayfish Pontastacus leptodactylus Esch. kept in a lightning regime that is close to natural under optimal or low pH values were studied. The heart rate was registered in real time using an original noninvasive fiberoptic method. Upon acidification, disorders in circadian cardiac rhythm and organism(More)
The responses of the osphradium in the freshwater mollusc Viviparus sp. and single osphradial neurons in the pond snail Lymnaea stagnalis to L-glutamine and L-asparagine as well as the changes in these responses under the effect of heavy metals (Cu, Cd) were recorded electrophysiologically. The functional connections of the osphradium with the identified(More)
216 It is known that an organism functional system may exhibits rhythms of different frequency bands. Ultradian rhythms (URs) are of great interest in study physiological and behavioural characteristics as they play an important role in the life process of living beings and can be revealed at different levels of their organization [1]. For instance, the(More)
