Temporal Interference Stimulation of Centromedian‐Parafascicular Complex in Disorders of Consciousness: A Pilot Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Treatment of disorders of consciousness (DoC) remains a major clinical challenge, and noninvasive, targeted modulation of deep brain structures has emerged as a promising therapeutic strategy. We aimed to evaluate the feasibility/safety and preliminary effects of thalamic temporal interference stimulation (TIS) targeting centromedian‐

INTERNAL CARDIAC PACEMAKERS [PDF]

American Journal of Roentgenology, 1967
There are two main pacemaker systems used in controlling the cardiac rate in Severe heart-block patients: (1) asynchronous, and (2) synchronous or P-wave actuated.These pacemakers transmit current to the electrodes by direct wire or electromagnetic communications.The main techniques of applying the myocardial electrodes to the ventricles are: (1 ...

Novel Insights into the Sinoatrial Node in Single-Cell RNA Sequencing: From Developmental Biology to Physiological Function

Journal of Cardiovascular Development and Disease, 2022
Normal cardiac automaticity is dependent on the pacemaker cells of the sinoatrial node (SAN). Insufficient cardiac pacemaking leads to the development of sick sinus syndrome (SSS). Since currently available pharmaceutical drugs and implantable pacemakers
