Die Angaben in den zugehörigen Film und Text zur Verfügung gestellt haben wichtige Schritte vorgesehen, um ausreichend erfassen die Aktivität in der MRO des Krebses in situ. Ein Ziel unseres Berichts ist es, das Bewusstsein in das Potenzial für diese Vorbereitung Anstieg der Studierendenzahlen führen investigative Labors grundlegende Konzepte in der Sinnesphysiologie zu lehren. Die Vorbereitungen sind sehr robust in Lebensfähigkeit, während in einer minimalen Kochsalzlösung gebadet werden. Die Motorsteuerung auf der MRO Muskeln identifiziert worden ist, sondern die Regulierung der Übertragung und das Potenzial der synaptischen Plastizität sowie die Wirksamkeit der Übertragung für die erregenden und hemmenden Neuronen, bleibt eine offene Umgebung für die Untersuchung (Elekes und Florey, 1987a, b; Florey und Florey, 1955; Kuffler, 1954; Kuffler und Eyzaguirre, 1955). Dieses Präparat kann verwendet werden, um eine Reihe von experimentellen Bedingungen wie auch das natürliche Verbreitungsgebiet der Fortbewegung innerhalb der Tier untersuchen, um ein besseres Verständnis der Biologie des MRO für Primär-Research sowie demonstrative Zwecke verwendet werden. Edwards et al, 1981;;. Purali, 1997; Rydqvist und Purali, 1991; Rydqvist Die biophysikalischen Eigenschaften dieser sensorischen Neuronen wurde teilweise in ihrer Art der Anpassung ist in der neuronalen Aktivität mit einem gehaltenen Reiz (Brown et al, 1978 angesprochen und Swerup, 1991). Doch nur wenige Berichte Adresse Neuromodulation auf diesen sensorischen Rezeptoren und die damit verbundenen Muskelfasern (Cooper et al, 2003;. Pasztor und Macmillan, 1990). Die Berichte befassen sich mit nur ein paar der vielen Verbindungen, die bekanntermaßen in der Hämolymphe werden. Viele Modulatoren und Cocktails von Modulatoren bleiben auf dem MRO-Komplex (Muskeln und Neuronen) untersucht werden. Pasztor und Macmillan (1990) hat die Neuromodulatoren 5-HT und Octopamin auf die Aktivität der HRGs zwischen verschiedenen Arten Krebs zu untersuchen und stellte fest, dass es Arten Unterschiede. Sie haben nicht im Detail die langfristigen Einflüsse dieser Neuromodulatoren noch die Auswirkungen auf die Aktivität bei unterschiedlichen statischen Positionen der MRO zu untersuchen. . Rabin et al, 2009;;. Marino et al Diese Art der Zubereitung kann das Verständnis der Grundlagen der Sinneswahrnehmung und Regulierung der neuronalen Verarbeitung, die wichtig in der Rehabilitation und Disease-Management für Menschen mit motorischen Einheit Abnormitäten (Patel et al, 2009 wird die Beihilfe ., 2010). Die verschiedenen Arten von Ein-und Brand-Muster für die Überwachung der Gelenkbewegungen in zugänglichen wirbellosen Präparate können in der Robotik / Prothese (Macmillan und Patullo, 2001) verwendet werden. Es gibt immer noch viele Fragen warten auf Antworten in diesem Präparat, das von Vorteil sein in eine Reihe von Möglichkeiten kann.

muscle receptor organs in the crayfish abdomen: a student laboratory exercise in proprioception

Der primäre Zweck dieses Experiments ist es, die primären sensorischen Neuronen Informationen zu vermitteln gemeinsamer Bewegungen und Positionen als propriozeptive Informationen für ein Tier zu demonstrieren. Ein weiteres Ziel dieses Experimentes ist es, Anatomie der Vorbereitung durch die Färbung, Dissektion und Betrachten von Neuronen und sensorischen Strukturen lernen unter einem Binokular. Dies wird durch grundlegende neurophysiologische Ausrüstung an die elektrische Aktivität von einem gemeinsamen Rezeptor Orgel und Färbetechniken Rekord durchgeführt. Der Muskel-Rezeptor-Orgel (MRO)-System in der Krebse ist analog zu den intrafusalen Muskelspindel bei Säugetieren, die in die als eine vergleichende Modell, das leichter zugänglich für elektrophysiologische Aufzeichnungen ist AIDS. Darüber hinaus sind diese identifizierbaren sensorischen Neuronen unter Vorbereitungen. Die Zubereitung ist in einem minimalen Kochsalzlösung für Stunden, die zugänglich für studentische Laborübungen lebensfähig ist. Die MRO ist auch anfällig für Neuromodulation, die spannenden Fragen in den Standorten der modulatorische Wirkung und die Integration von dynamischen Signalen von Bewegungen und statischen Position zusammen mit einem Gewinn, der in das System geändert werden kann fördert.
