One of the aspects of safely and accurately targeting brain regions with transcranial focused ultrasound is estimating the trajectory and intensity of the ultrasound waves using computer simulations. We are currently working on acoustic simulations in order to estimate and visualise the path of the acoustic pressure wave generated by the ultrasound transducer through the skull. We use a Matlab-based toolbox, k-Wave (Treeby and Cox, 2010), to perform acoustic simulations based on individual skull anatomy and transducer positions to get a better picture of where the ultrasound wave is going and how much pressure is being applied.
The spatiotemporal neural characteristics of reward anticipation in addiction: a simultaneous EEG-fMRI investigation // 2020 - 2024
The decision-making brain system is widely study in neurosciences, but the exact mechanism that underly decision are not fully understand yet.
The aim of the experiment is to study the neural mechanisms of reward anticipation and reward delivery, one of the fundamental aspects of decision-making and learning. We supposed that this mechanism is different in some psychiatric illness such as addiction or Obsessive-Compulsive Disorder. Thus, our purpose will be to compare the neural networks of people who previously suffered from alcohol abuse to people that did not to help diagnosis and treatment
