A New Versatile and Powerful Microcomputer Data Acquisition System for Both Undergraduate Physiology Laboratories and Research

动物生理学的教学正在现代化，通过增加六个多功能、廉价的微型计算机数据采集站和与微型计算机连接的生理学仪器，提高了本科生的研究能力。生理学站对课程进行了若干改进，包括：1)增加新的实验；2)学习现代数据采集技术的学生；3)微型计算机，与投影仪接口，用作课堂教学辅助设备；4)学生对科学方法有了更好的理解，因为他们花了更多的时间设计和执行实验；5)更多本科生承担个人研究项目。为此目的已获得以下仪器：Macintosh LC微型计算机，打印机，数据采集硬件和软件（BIOPAC的Acknowledge），换能器，放大器，刺激器，微电极站设备和上皮电压钳。新的实验包括：1)蛙神经肌肉接点的膜和突触生理学；2)小龙虾后肠平滑肌的生理和药理研究；3)蛤心膜生理，采用蔗糖间隙法；4)蟑螂腿神经的神经感觉生理学；5)电压箝位蛙皮肤Na+输运机制；6)通过心血管功能实验室（cardiovascular Function Lab， CFL）刺激心血管生理。CFL伴随着麻醉大鼠的实际血压测量。

The teaching of animal physiology is being modernized and undergraduate research capabilities improved by adding six highly versatile, inexpensive microcomputer data acquisition stations and physiological instruments which interface with the microcomputers. The physiology stations provide several curricular improvements, which include: 1) adding new experiments; 2) students learning modern data acquisition techniques; 3) the microcomputer, interfaced to an overhead projector, used as a classroom teaching aid; 4) students gaining a better understanding of the scientific method because they spend more time designing and performing experiments; and 5) more undergraduates undertaking individual research projects. The following instruments have been acquired for this purpose: Macintosh LC microcomputers, printers, data acquisition hardware and software (BIOPAC's Acknowledge), transducers, amplifiers, stimulators, equipment for a microelectrode station and an epithelial voltage clamp. The new experiments include: 1) membrane and synaptic physiology of frog neuromuscular junction; 2) physiology and pharmacology studies of smooth muscle in crayfish hindgut; 3) membrane physiology of clam heart, employing the sucrose gap technique; 4) neurosensory physiology of cockroach leg nerve; 5) mechanism of Na+ transport across voltage-clamped frog skin; and 6) cardiovascular physiology stimulated with Cardiovascular Function Lab (CFL). CFL accompanies actual blood pressure measurements made in anaesthetized rats.
