15 صفحه اولCholinergic modulation of the swimmeret motor system in crayfish.
1. The muscarinic agonist pilocarpine induced the swimmeret motor pattern in resting isolated preparations of the crayfish abdominal nerve cord and modulated the burst frequency in a dose-dependent manner. 2. Nicotine did not elicit rhythmic activity in resting isolated preparations but increased the burst frequency in active preparations. Nicotine produced higher burst frequencies than pilocar...
متن کاملMotor programme switching in the crayfish swimmeret system.
Intracellular and extracellular recordings have been made from neurones of the swimmeret system in the semi-isolated abdominal ganglion of the crayfish during rhythmic activity. Extracellular recordings commonly reveal a motor programme (MP1) consisting of low-amplitude symmetrical power and return stroke activity with phase-constant posterior-to-anterior intersegmental coordination. Occasional...
متن کاملFive types of nonspiking interneurons in local pattern-generating circuits of the crayfish swimmeret system.
We conducted a quantitative analysis of the different nonspiking interneurons in the local pattern-generating circuits of the crayfish swimmeret system. Within each local circuit, these interneurons control the firing of the power-stroke and return-stroke motor neurons that drive swimmeret movements. Fifty-four of these interneurons were identified during physiological experiments with sharp mi...
متن کاملThe scope of the crustacean immune system for disease control.
The culture or wild capture of marine and freshwater shellfish, including crustaceans, is without doubt a key source of protein for a burgeoning world population. Historically the expansion of aquaculture has, however, been accompanied by the increased incidence of economically significant diseases, most notably of viral and bacterial origin. Since the late 1970s great progress has been made in...
