Low-intensity transcranial ultrasound stimulation helps modulate brain activity and behaviors associated with a range of psychiatric disorders, a new study reports.
Combining focused ultrasound with microbubble treatments weakens the connection between blood-brain barrier cells, effectively allowing for better delivery and absorption of drug treatments.
Transcranial focused ultrasound (tFUS) can help elevate mood and decrease activity in brain networks associated with psychiatric disorders when directed at the ventrolateral prefrontal cortex.
Ultrasound can propagate through solid surfaces and activate voice recognition systems, allowing the person who initiates the attack to also hear the phone's response. Out of 17 different phone models tested, 15 were vulnerable to ultrasonic wave attacks.
A new technology known as sonogenetics can control neural activity by using sound frequencies. The technology could be used to non-invasively treat a range of neurological conditions, including Parkinson's disease and epilepsy.
Using transcranial focused ultrasound in combination with injectable microbubbles, researchers open a pathway through the blood-brain barrier. The technique allows drugs to penetrate the brain and trigger therapeutic effects for those with neurodegenerative diseases.
A study of macaque monkeys reveals low-intensity ultrasound can both generate and suppress signalling in the brain and modulate normal function. The ultrasonic stimulation alters counterfactual thinking, allowing the ability to decide upon a better alternative in decision-making tasks.
Researchers say a quick scan of blood vessels in the neck during mid life may help to predict those at risk of dementia up to ten years before symptoms appear.
Researchers use focused ultrasound to safely and non-invasively open the blood-brain barrier in Alzheimer's patients.
