廠牌名稱:
實驗鼠腦部若發生病變或損傷可能會造成一些異常的行為,原地打轉就是一項常見且明顯的指標。Columbus Instruments Rota-Count 8 就是為了量測動物原地打轉的一套設備,可進行最多8隻動物(選配擴充)全自動的動物旋轉計數,讓您省去大量的人工觀察計數時間。

產品特點

Rotational behavior is often used as an index of pharmacological/dopaminergic performance in animals subjected to brain lesions that induce rotational behavior. Rotat-Count-8 is a thirty-two station rotation monitoring system that records full and partial turning motion small laboratory animals. In practice, the subject wears a harness to which a light and flexible tether has been affixed. The tether is secured to a rotary encoder that monitors the angular direction of the subject. The rotary encoder shaft is supported by ball bearings, which require less than five inch-ounces of torque, and is not an obstacle to the subject's normal motion. The rotary encoder resolves each revolution into 100 parts (3.6 degrees). The Rota-Count 8 monitors both clockwise and counter-clockwise turning behavior. Each Rota-Count 8 unit monitors 8 subjects. Up to four Rota-Count 8 units connect together using standard category 5 network/communication patch cables.

The Rota-Count 8 is supplied with Windows 2000/XP software to install on a PC or Laptop computer for collection of experiment data and disk file storage in .CSV format. The software monitors full and partion revolutions. Partial revolutions are defined by the operator and can be set from 15 to 180 degrees in increments of 15 degrees. The operator has the option to enter individual subject comments as well as general experiment comments. The experiment control display provides a view of the running tabulation of rotational scores for each subject during the execution of an experiment. A 'Staggered Start' feature allows the operator to individually initiate data collection from each animal. This capability gives sufficient flexibility that a sole operator may prepare and monitor multiple subjects. A 'Simultaneous Star' is supported if all active subjects require a common starting time.
