Pulsed electric stimulation, coupled capacitively to different cell cultures of skeletal origin, caused immediate changes in the cellular levels of cyclic AMP and a later enhanced DNA synthesis. Changes both in cyclic AMP level and DNA synthesis were

The molecular nature of signal transduction in bacterial chemotaxis is virtually unknown. If the signal transduction is electrical in nature, an externally applied electric field should affect chemotactic behavior. We therefore studied the effect of

An external semi-automatic Pacemaker Function Analyzer (PFA) has been designed for routine examination (screening) of ambulatory-paced patients in general medical practice. The evaluation of the pacemaker (PM) function is based on recognition, decodi

The polarization characteristics of Pt-Ir and Elgiloy small-surface-area (10-12.5 mm2) pacemaker electrodes were studied at AC linear (sensing) and DC non-linear (pacing) conditions. The electrodes' AC polarization impedance was approximately equal t

The use of radio-telemetering has several advantages for the recording of EEG data from unrestrained subjects. By use of transistor techniques, miniaturization of the apparatus carried by the subject is made possible. Design considerations for a tran

A universal heart pacing method is proposed, making use of the atrial-synchronized and demand operation modes. The system includes an ECG-sensing network for control of the pacing action. Special logic design provides for processing the P- and QRS-wa

The phenomenon of tonal residue in stimulation of the hearing system by sinusoidally amplitude‐modulated tones is examined for its correlation with the temporal fine structure displacements of the basilar membrane. It is suggested that the deviatio

Pulsed electric stimulation, coupled capacitively to bone cells isolated from rat embryo calvaria, caused changes in the intracellular level of cyclic AMP and enhanced DNA synthesis. The capacitive method of electrical stimulation was characterized i
