1. The movement of labeled potassium ions has been measured across the innervated membranes of single isolated electroplaques, obtained from the organ of Sachs of Electrophorus electricus, mounted in an apparatus which allowed a separate washing of the two membranes. 2. Equations have been derived for a 3 compartment system in series in which tracer from a large pool in one outer compartment is...

Directed transfer function (DTF) method was used to assess brain connectivity disturbances in depression. The results were depicted as a model with the electroencephalographic (EEG) registration points, through which directions of bioelectric activity are defined. Transcranial magnetic stimulation (TMS) is an alternative treatment for drug-resistant depression and considered restore impaired co...

The quantification of the bioelectric phenomena originating in nervous and muscular tissues is an essential task in diagnosis within the field of Electromedicine. Clinical electromyography is the part of Clinical Neurophysiology focused on the neuromuscular system, and includes the study of the electrical activity of peripheral nerves (electroneurography), striated muscles (electromyography, in...

This paper is an early, and possibly premature, examination of some consequences of different mechanisms of ion permeation in the hope of providing a basis for progressing beyond the present treatments of bioelectric phenomena (cf. Hodgkin, Huxley, and Katz, 1952a, b, c, d, e) which, in the absence of knowledge of the details of the mechanism by which ions cross biological membranes, have neces...
