electrobasograph
An apparatus for measuring the weight bearing period of limbs during walking.
electrobasography

electrocardiograph
An instrument for recording the potential of the electrical currents that traverse the heart and initiate its contraction.
electrocardiography
1. A method of recording electrical currents traversing the heart muscle just prior to each heart beat.
2. The study and interpretation of electrocardiograms.
electrocardiophonographic
A reference to a method of electrically recording the sounds of the heart.
electrochromatography
A chemical separation technique in analytical chemistry, biochemistry, and molecular biology which is used to resolve and to separate mostly large biomolecules; such as, proteins.
Electrochromatography is a combination of size exclusion chromatography (gel filtration chromatography) and gel electrophoresis.
The term "gel" in this instance refers to the matrix used to contain, then separate the target molecules.
electrocochleography
1. A measurement of the electrical potentials generated in the inner ear as a result of sound stimulation.
2. The measurement of electrical activity produced when the cochlea is stimulated.
A needle electrode is passed through the eardrum and placed on the cochlea. The electrical activity is then recorded.
electroencephalograph
An instrument that measures electrical potentials on the scalp and generates a record of the electrical activity of the brain.
electroencephalography
The recording of the electric currents developed in the brain, by means of electrodes applied to the scalp, to the surface of the brain (intracranial) or placed within the substance of the brain (depth).
electrogastrograph
1. An instrument for recording the electrical activity of the stomach by means of swallowed gastric electrodes.
2. A graphic recording of the electrical phenomena associated with gastric secretion and movement.
electrogastrography
The recording of the electrical activity of the stomach as measured between its lumen (cavity) and the body surface.
