Principle and tasks
To record an electrocardiogram (ECG) between the left leg and the right and left arm (lead II according to Einthoven). To relate the ECG segments to the course of heart contraction (P wave, P-Q segment, QRS complex, T wave).
Principle and tasks:
Cardiac and vascular sonic measurement at different locations of the circulatory system. Measurement of the pulse rate at different levels of athletic loading.
What you can learn about:
To prepare a plot of blood pressure measurement and to read the values of systolic and diastolic blood pressure.
What you can learn about
Principle
Didactical blood pressure measurement system for wireless data transfer of measurement data from test person to computer, thereby permitting flexible and mobile experimental setup.
Tasks
To prepare a plot of blood p ...
To prepare a curve showing the change in skin temperature during smoking. To discuss different curves depending on the smoking habits of the test person.
Principle and exercises
This experiment records how skin temperature changes with time when someone is smoking with the help of a temperature sensor and the Cobra3 interface. How the temperature curve differs should be discussed with reference to the tested persons ...
Cigarette consumption influences the diameter and therefore the circulation of the peripheral blood vessels. This experiment studies the change of the finger temperature during smoking.
To prepare an electromyogram (EMG) from a contracting or relaxing upper arm muscle (biceps) using surface electrodes. Measurement of the frequency and the amplitude of the EMG at maximum concentration.
What you can learn ab ...
To trigger a stretch reflex in the lower leg musculature by tapping the Achilles tendon (Achilles tendon reflex). To record the compound action potential and determine the reflex latency and the conduction velocity.

Principles and tasks
To localize a source of sound using an artificial head. To measure the time difference and the difference in intensity of the sound waves incident on each ear of the artificial head.
To prepare curves demonstrating the regulation of body temperature. To discuss different curves depending on the conditions at the hand of the test person.
Demonstration of the regulation of body temperature.
Tasks:
How can our body temperature be regulated? This experiment shows why we sweat in summer and wear gloves in winter.
Determination of the visual field of the right and left eye for white, blue, red and green. Detection of any visual field deficiency (scotoma). Location of the blind spot (site of optic nerve emergence). The extent of the visual fields of bo ...
To determine the flashing frequency of an LED at which the impression of a continuous light just occurs. To change the direction of incidence of the light using a perimeter. To determine the flicker fusion thershold of the left and right eye in relation to ...
