BIOLOGY - HIGHER EDUCATION

Lessons include blood pressure, ECG analysis, heart sounds, and pulse. Students can make single-, three-, six- and 12-lead ECG recordings, familiarizing themselves with einthovens triangle and mean electrical axis of the frontal plain. Students perform blood pressure measurements using a cuff, with stethoscope, employing korotkoff sounds to make determinations of systolic/diastolic pressure. Students can also utilize the latest technology for continuous noninvasive BP recordings. Use the bioimpedance cardiac output (CO) module on human and animal subjects to record stroke volume and cardiac output. By measuring continuous BP, simultaneous with flow (cardiac output), students can examine vascular resistance.

Use the BSL hardware with suitable glass micro electrodes to demonstrate membrane potential with the frog sartoris muscle or the the popular Crawdad CD-ROM lab manual for neurophysiology, by wyttenbach, johnson, and Hoy. ISBN 0-87893-947-4. The experiments demonstrate the principle of homeostasis and serve as a good introduction to electro physiology recording techniques.

The Biopac Student Lab is an excellent tool for comparative biology programs because students can compare data from their own bodies with data recorded from a variety of animals. The curriculum covers most of the major physiological systems, including brain, muscle, pulmonary, cardiovascular, and CNS.

SE the system to record gastric signals in humans and animals or monitor isolated intestinal (gut) strips in a tissue bath experiment. Monitor the EGG before and after food digestion. Examine gastric slow wave propagation, peristaltic (slow waves) propagation, and gastrointestinal motility.

Students can use the new gas analysis system to monitor expired CO2 and O2levels for detailed metabolic studies with human and animal subjects. Take measures to study ventilation and heat exchange. Use the dissolved O2 probe and lesson to measure the oxygen consumption of a goldfish. Chambers, facemasks, and tubing accessories provide setup options for any protocol.

Study EEG under a variety of conditions to explore relaxation and brain rhythmsthe software can filter and display each rhythm separately: alpha, beta, delta, and theta. Study alpha rhythms in the occipital lobe, reaction times, and hemispheric asymmetry. Use the system to demonstrate changes in the parasympathetic and sympathetic nervous system. Add EOG (occipital signal) to study eye movement, saccades, tracking, angular displacement, or ocular fixations. Use the stimulator to study evoked responseauditory, visual, or somatosensory. Record reaction time and measure nerve conduction velocity. The system samples quickly enough to easily record spontaneous nerve activity from small animals and insects.
