Mapping Cavefish Brains Leads to Neural Origin of Behavioral Evolution

While studied for nearly a century, little is known about how cavefish brains differ. A study is the first to look inside their brains with millimeter resolution to start to understand how the individual neurons and brain regions that drive complex behaviors, including sleep and feeding have evolved. This work has broad implications for the understanding of how brains evolve in many different animal models and is hoped to be widely used by the scientific community.

New dopamine sensors could help unlock the mysteries of brain chemistry

In 2018, Tian Lab at UC Davis Health developed dLight1, a single fluorescent protein-based biosensor. This sensor allows high resolution, real-time imaging of the spatial and temporal release of dopamine in live animals. Now, the team expanded the color spectrum of dLight1 to YdLight1 and RdLight1. The increased light penetration and imaging depth of these variants provide enhanced dopamine signal quality allowing researchers to optically dissect dopamine’s release and model its effects on neural circuits.

University of Miami Health System researchers publish overview of evidence that COVID-19’s impact affects much more than the lungs

Studies suggest COVID-19 patients may at first present with atypical neurologic, gastrointestinal, cardiac and musculoskeletal imaging findings, which are more likely to go undiagnosed, according to the paper “Clinical Characteristics and Multisystem Imaging Findings of COVID-19: An Overview for Orthopedic Surgeons,” published August 17 in HHS Journal: the musculoskeletal journal of Hospital for Special Surgery.

New Study Evaluates the COVID-19 Impact on Imaging Volumes

As a result of the COVID-19 pandemic many radiology departments have experienced a rapid decline in imaging case volumes. This new study, funded by the Harvey L. Neiman Health Policy Institute and published online in Journal of the American College of Radiology (JACR), evaluates the impact of the pandemic on imaging case volumes using real-world data from a large healthcare institution.

Chest X-Rays in Emergency Rooms Can Help Predict Severity of COVID-19 Illness in Young and Middle-aged Adults

Chest X-rays performed on young and middle-aged adults with COVID-19 when they arrive at the emergency room can help doctors predict who is at higher risk of severe illness and intubation, Mount Sinai researchers report.

Scientists and neurosurgeon team up to develop novel imaging device for babies with brain disorders

Using night-vision goggle technology, near-infrared light, and high-resolution detectors, a wearable imaging device for awake infants with brain disorders was developed by a team of scientists and a pediatric neurosurgeon at UTHealth. Cap-based Transcranial Optical Tomography (CTOT), which utilizes a cap for the baby’s head, is the first high-resolution, whole-brain functional imaging device that does not require the baby to be put under anesthesia.

Cell Membrane Proteins Imaged in 3-D

A team of scientists including researchers at the National Synchrotron Light Source II have demonstrated a new technique for imaging proteins in 3-D with nanoscale resolution. Their work, published in the Journal of the American Chemical Society, enables researchers to identify the precise location of proteins within individual cells, reaching the resolution of the cell membrane and the smallest subcellular organelles.
