New publication: Acoustic coordinated reset therapy for tinnitus with perceptually relevant frequency spacing and levels
The purpose of this article was to develop a more advanced, auditory filter-based theoretical basis for the selection of the acoustic neuromodulation signals that incorporates both a more perceptually relevant frequency scale relative to the frequency matched to the tinnitus pitch, as well as known changes associated with neuromodulation signal level and magnitude of sensorineural hearing loss at the frequency of the neuromodulation signal.
New publication: A rapid beam simulation framework for transcranial focused ultrasound
The Hybrid Angular Spectrum (HAS) framework can be used to simulate the position, temperature, and shape of a focused ultrasound focal spot.
New publication: Elimination of peripheral auditory pathway activation does not affect motor responses from ultrasound neuromodulation
Transcranial ultrasound with a rectangular waveform envelope activates the auditory system when intended for a motor area, but these waveforms can be smoothed to eliminate the auditory responses while maintaining motor responses.
New publication: Measurements of the Relationship Between CT Hounsfield Units and Acoustic Velocity and How It Changes With Photon Energy and Reconstruction Method
While several studies have investigated the relationship between acoustic velocity and CT Hounsfield units (HUs), these studies have largely ignored the impact of X-ray energy, reconstruction method, and reconstruction kernel on the measured HU, and therefore the estimated velocity, and none have measured the relationship directly.
New publication: Frequency Dependence of Ultrasound Neurostimulation of the Mouse Brain
Ultrasound holds great promise as a tool for neurostimulation because, unlike other neurostimulation technologies, it is non-invasive, can target regions deep within the the brain, and can focus to cubic millimeter volumes.
