![]() Vascular ultrasound is also the most commonly used test to follow-up patients after they have undergone a vascular procedure such as a bypass graft or stent. Neurosound can be used to achieve better brain health, learning abilities, as well as enhanced cognition. We can use TCD to help identify shunting (abnormal flow) in the heart by injecting IV fluids with microbubbles in the arm vein of a patient and monitoring their brain sound waves. Neuro-sound is a form of neuro-feedback wherein auditory stimuli, such as music, binaural beats or positive affirmations are utilized to influence brain wave chemistry, to our desired effect. We can diagnose narrowing of arteries and determine the severity of narrowing to guide therapies. Vascular ultrasound can be used for: evaluation of blood flow in the arteries and veins of the body to detect the presence, severity and specific location of disease. When the speed of blood flow in a blood vessel is too fast, this indicates a narrowing (blockage). The ultrasound machine can calculate blood flow in the vessel based on the speed of the reflecting sound waves. The sound waves are recorded and displayed on a computer screen to make an image of the blood vessel. How does it work?ĭuring a vascular ultrasound study, sound waves are transmitted and reflect off of the blood cells moving within the blood vessels and then return to the ultrasound machine. Unlike other medical tests, ultrasound does not require radiation or contrast dye. Non- invasive means the procedure does not typically require the use of needles or anesthesia. Vascular ultrasound can be used to evaluate arteries or veins in nearly any part of the body, including blood vessels in the neck (carotid ultrasound) or brain (transcranial ultrasound or TCD). Listeners will hear, feel and see the brain activity either in the normal state or a seizure state, and all in its natural time course and with its awesome rhythms and severity.What is vascular ultrasound/neurosonology?Ī vascular ultrasound is a noninvasive test method (also called a duplex study) used to examine the circulation in the blood vessels of the body. The final product of this unique collaboration will be a device that creates audio and 3D visualizations directly from arrays of intracranial brain signals in patients with epilepsy. While the PI will contribute with his unique expertise in intracranial electrophysiological recordings and signal processing, the co-PI will contribute with his internationally known and ground-breaking method of “musification” of biological, medical, and environmental sources. In this collaborative project, the PI is the Director of Medication-Resistant Epilepsy Program at Stanford and the Co-PI is the Director of Center of Computer Research in Music and Acoustics. At a higher level of abstraction, advanced sonification and visualization software can track patterns over time in the data, uncovering the individual regularities, which may then lead to larger patterns to be found in common among many patients with epilepsy. You can move through the 3D visual and auditory space to pinpoint the origin of specific patterns, the entrainment of neighboring areas and so on. Couple this with visualizations of the same flowing data in 3D projections, and the workings of the brain become navigable. For example, by “sonifying” the data patterns - turning them into a kind of music - the human ear can follow the nuances and shifts of brain states with a surprising deftness. ![]() It is here that collaboration between School of Humanities and Sciences and School of Medicine holds great promise, certain to advance the possibilities of representing brain signals in a novel and illuminating way. Recordings from inside the brain yield unprecedentedly rich data-sets of electrical signals both in normal and in seizure states. ![]() Interdisciplinary Initiatives Program Round 6 - 2012
