ATRACURIUM AND DOUBLE BURST STIMULATION

Burst Stimulation

The brain is a complex adaptive system, processing information from the internal and external environment. Information is transmitted within the nervous system in at least 2 separate firing patterns, tonic and burst firing. Burst firing consists of closely spaced spikes at high frequency (eg 500 Hz) followed by quiescent periods. It has been proposed that burst firing is a signal detector, a ki...

Atracurium and intraocular pressure.

The effect of atracurium on intraocular pressure was studied by comparing it with pancuronium in a randomised controlled trial. The intraocular pressure was measured in patients undergoing cataract surgery before administration of the muscle relaxant, at 1, 3, and 5 minutes after its administration, and at 1 minute after tracheal intubation. Atracurium was found to decrease intraocular pressure...

Theta Burst Stimulation of the Human Cerebellum

Theta Burst Stimulation of Human Cortex

It has proved possible in experimental animals to manipulate synaptic efficiency using direct electrical stimulation of central nervous pathways. The introduction of transcranial methods of non-invasively stimulating the human brain raised hopes that similar effects could be produced in humans, with the potential for eventual therapeutic application in disease states. However, largely due to sa...

اثر Burst Repetitive Transcranial Magnetic Stimulation بر روی وزوز مزمن گوش

زمینه و هدف : وزوز گوش درک صدا در غیاب یک محرک شنوایی است ویک علامت شایع در اختلالات سیستم شنوایی است . فرم مزمن 5 تا 15% جمعیت عمومی را درگیر می کند ودر 1 تا 3% جمعیت موجب ناتوانی مشخص در کیفیت زندگی می شود. Repetitive (rTMS)Transcranial Magnetic Stimulation روشی است که در دهه اخیر اثرات آن بر روی وزوز گوش بررسی شده است و نتایج مطلوبی داشته است. در این مطالعه اثرات rTMS Burst بر روی بیماران مب...
