- Person Presentation: Paul Hernandez Herrera ()
Paul Hernandez-Herrera is an applied mathematician and postdoctoral fellow who develops algorithms for image analysis at the Institute of Biotechnology, National Autonomous University of Mexico. His prior work includes creating algorithms to automatically identify and trace tubular structures (such as neurons, sperm flagella, and blood vessels) from 3D images. Currently, he is pioneering the use […]
- The Biggest Brain Maps Ever Created Are Pushing the Frontiers of Neuroscience ()
Our quest to understand the brain’s connections is a bit like aliens trying to understand Earthlings from outer space. Imagine having to track down every single person and their conversations across different continents, reconstruct noisy snippets into coherent messages, and from that data, infer the zeitgeist of the human race. That, essentially, is what neuroscientists […]
- Biology’s Most Ambitious Map Yet: The Human Cell Atlas ()
For more than two decades, using twin telescopes pointed skyward, scientists have been mapping the universe. From the outset, the trove of data they collect has been available to the scientific community and the public, fueling discovery and revolutionizing astronomy globally. Just last year, for example, the most comprehensive reference map of the cosmos was […]
- CZI Awards Over $5M to Advance Technologies and Expand Global Access to Bioimaging ()
Today, the Chan Zuckerberg Initiative (CZI) announced more than $5 million to advance bioimaging technologies, increase access to these tools, and build capacity for biomedical researchers. Of the funding, $1 million will support 41 plugin projects for the imaging analysis tool napari, while $4.1 million will support 17 projects to increase access to imaging instrumentation […]
- New Brain Maps Can Predict Behaviors ()
Rapid advances in large-scale connectomics are beginning to spotlight the importance of individual variations in the neural circuitry. They also highlight the limitations of “wiring diagrams” alone. A 3D model of closely bundled pyramidal neurons running through cortical layer 5 of a mammalian brain; the neurons have been colored differently to distinguish them. Researchers have […]
- Calcium imaging ()
Calcium imaging is a microscopy technique to optically measure the calcium (Ca2+) status of an isolated cell, tissue or medium. Calcium imaging takes advantage of calcium indicators, fluorescent molecules that respond to the binding of Ca2+ ions by fluorescence properties. Two main classes of calcium indicators exist: chemical indicators and genetically encoded calcium indicators (GECI). […]
- Learning from imaging data to model brain activity ()
In this article, we introduce VanDEEPol, a hybrid AI/mechanistic model to predict brain activity and structure from imaging data. The model significantly boosts predictive accuracy compared to previous methods. By predicting brain activity from relatively sparse imaging data, VanDEEPol may eventually help to detect medical disorders or design brain-computer interfaces. Intricate interactions among billions of […]
- Virginia Tech Launches ‘Next Generation’ Human Brain Imaging Lab ()
Summary: Virginia Tech researchers have received a grant to deploy a new brain imaging technology called optically pumped magnetometry which can assist with studying the nuances of social interactions. Source: Virginia Tech As you read this story, your brain’s cells are generating electrical currents that emit infinitesimally small magnetic fields. Now, Virginia Tech scientists can […]
- Axonics’ SNM system wins FDA nod for 3T-MRI scans ()
Axonics Modulation Technologies (NSDQ:AXNX) announced today that it has won FDA approval for full-body 3 Tesla (T) MRI scanning for patients implanted with its r-SNM sacral neuromodulation system. The premarket approval supplement represents an upgrade from a previous PMA conditional labeling for r-SNM, which allowed for for full-body scans using 1.5T MRI scanners. With this […]
- CT Scan with living tissues or bodies or living human beings ()
Hi, I don’t know if there is a scanner that exists like a CT Scan but for living tissue, I did a google search without finding anything, maybe a PET/CT Scan. I had a discussion with my father following a visualisation on youtube about a CT Scanner this one: https://www.youtube.com/watch?v=9usf3kJL7mc (digital autopsy) In the future […]
- Alcor’s Chief Technical Coordinator wrote: ()
As Steve Graber, Alcor’s Chief Technical Coordinator wrote: “A big step forward for the Alcor CT Scan analysis program last year was the development of a CT color lookup table that allows us to now determine the overall perfusion level for each Alcor patient. This is the first time that we’ve been able to ‘look […]
- https://en.wikipedia.org/wiki/Digital_autopsy A digital autopsy is a non-invasive autopsy ()
A digital autopsy is a non-invasive autopsy in which digital imaging technology, such as with Computerized Tomography (CT) or Magnetic Resonance Imaging (MRI) scans, is used to develop three-dimensional images for a virtual exploration of a human body. Digital autopsy, simply, means conducting autopsy in computerized environment by digital tools. The first step of digitizing […]
