Laboratory behavioural assay of insect magnetoreception: magnetosensitivity of Periplaneta americana.
A relatively simple all-laboratory behavioural assay of insect magnetoreception has been developed. We found non-conditioned reactions of American cockroach to the periodical shifts of the geomagnetic field. The movement activity of animals individually placed into Petri dishes was scored as a number of body turns. Test groups were exposed to a 90-min interval with the horizontal component of t...
متن کاملThe ultrastructure of the perineurium in two insect species, Carausius morosus and Periplaneta americana.
The organization of the perineurium in two insect species (Carausius morosus and Periplaneta americana) has been examined with the electron microscope. In both species this cellular layer has been found to possess an extensive system of tortuous channels between the lateral cell walls. These channels are open at the outer margin adjacent to the fibrous connective-tissue sheath, but appear to be...
متن کاملThe metabolism of acetylcholine in the intact central nervous system of an insect (periplaneta americana l.).
The insect central nervous system is known to be remarkably insensitive to applied acetylcholine. This effect was first demonstrated in the terminal abdominal ganglion of the cockroach when it was shown that synaptic transmission was unaffected by concentrations of up to io~ M acetylcholine in the bathing solution (Roeder, 1948). This level of acetylcholine is more than two orders higher than t...
متن کاملThe Structure of Intersegmental Muscle Fibers in an Insect, Periplaneta Americana L
The organization of intersegmental muscle fibers associated with the dorsal abdominal sclerites of the cockroach is described. These fibers correspond closely, in the disposition and derivation of the membranes of the transverse tubular system and sarcoplasmic reticulum cisternae, with insect synchronous flight muscle fibers, but differ markedly from these in their fibrillar architecture and mi...
متن کاملThe penetration of acetylcholine into the central nervous tissues of an insect (Periplaneta americana L.).
The precise physiological role of acetylcholine in synaptic transmission in the insect central nervous system has been a subject of some speculation and controversy. One of the main difficulties involved in postulating the existence of a conventional cholinergic system in the insect central nervous system has been the relative insensitivity of intact ganglia to applied acetylcholine solutions (...
