Illustrates some simple experiments which may be performed on a decerebrate rabbit preparation. Shows how to set up the preparation for recording arterial blood pressure, electrocardiogram and respiration,...
Dissection of the frog sciatic nerve and a demonstration of its electrical properties by connection to an oscilloscope and observation of signal characteristics.
Experiment measuring surface tension at different surface areas of rat lung washings. Experiment related to respiratory distress of the newborn and the surface tension of bubbles of different radii.
Monocular pattern-deprivation was achieved by eyelid suturing of one eye at the time of natural eye-opening. When the cats were about eight months old they were forced to use their deprived eye by means of a...
Demonstrates some of the factors affecting reaction kinetics, leading to deductions of rate equations, rate determining steps, order, activation energies, molecularity and reduction mechanisms. Shows the...
Depicts removal of the apical ectodermal ridge at differing stages affecting the extent of limb outgrowth. Reversal of the wing-bud apex produces an extra hand. An extra wing tip forms when the zone of...
The types of cell in the cat’s retina and their basic actions are explained with the help of an animated diagram. Extracellular microelectrode recording from the axon of the ganglion cell is then shown....
Shows experiments performed on the decerebrate rabbit and is intended both as a guide to the general principles of arterial blood pressure regulation and as an aid to practical work.
Shows research on effects of delayed auditory feedback. Begins with demonstrations of effect on human subject’s reading aloud when his voice is fed back through ear-phones with a delay of a quarter of a...
Electrodes are implanted in different parts of the hypothalamus of rats. Animals can obtain electrical stimulation by pressing a lever, or stimulation can automatically be applied. Shows effects of brain...
