Purpose: High resolution fMRI is a rapidly growing research field focused on capturing functional signal changes across cortical layers. However, the data acquisition is limited by low spatial frequency EPI artifacts; termed here as Fuzzy Ripples. These artifacts limit the practical applicability of acquisition protocols with higher spatial resolution, faster acquisition speed, and they challenge imaging in lower brain areas.

- The study investigates how Hurricane María affected substance use among Puerto Rican youth, focusing on identifying risk and protective factors related to substance use post-disaster.
- Using a large dataset of school surveys conducted from February to June 2018, the research analyzed the relationship between social support (adult, teacher/counselor, and peer), trauma symptoms, and substance use levels.
- Results indicated that strong adult social support significantly reduced the likelihood of high substance use, while teacher/counselor support also contributed to lower rates, highlighting the importance of social networks in crisis recovery.
Purpose: Driven by the Lorentz force, acoustic noise may arguably be the next physiological challenge associated with ultra-high field MRI scanners and powerful gradient coils. This work consisted of isolating and mitigating the main sound pathway in the NexGen 7 T scanner equipped with the investigational Impulse head gradient coil.
Methods: Sound pressure level (SPL) measurements were performed with and without the RF coil to assess its acoustic impact.
Vocal attractiveness influences important social outcomes. While most research on the acoustic parameters that influence vocal attractiveness has focused on the possible roles of sexually dimorphic characteristics of voices, such as fundamental frequency (i.e.

Materials And Methods: Gradient impulse response function measurements were performed at 5 sites spanning field strengths from 7 to 11.7 T, all of them sharing the same exact whole-body gradient coil design.
