Neuroinvasiveness of SARS-CoV-2 shown by viral RNA and inflammation in the brain The coronavirus disease 2019 (COVID-19) pandemic has claimed well over 2.4 million lives, but its long-term sequelae are still being identified. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) produces an infection that may be associated with a wide spectrum of disease, from asymptomatic to critical or terminal respiratory failure or multi-organ dysfunction. A new preprint on the bioRxiv server describes the results of a macaque study that showed the development of neurological features of inflammation, following infection by SARS-CoV-2. Neurological symptoms in SARS-CoV-2 infection SARS-CoV-2 primarily affects the respiratory organs, but in about a third of hospitalized COVID-19 patients, neurological manifestations are present. These include anosmia or dysgeusia, delirium, impaired consciousness, seizures, or psychosis. Some patients also develop Parkinsonism. ....
Researchers identify a neural pathway critical to correcting behavioral errors Mount Sinai researchers have identified a neural pathway through which the brain detects errors and guides subsequent behavioral improvement. This process, called cognitive control, is frequently dysregulated in a wide range of psychiatric disorders. The team s research, published February 19 in Neuron, also suggests that neurostimulation of this brain pathway could provide an important mechanism for attention adjustments following behavioral errors. When errors are committed, such as missing a stop sign or running a red light while driving, it s important for our survival to immediately adapt behavior by paying more attention to prevent further errors. This ability to adapt behavior after erroneous actions are one of the key components of human cognitive control. ....
Neurons activated by visual stimulus keep more active during subsequent sleep, study shows When you slip into sleep, it s easy to imagine that your brain shuts down, but University of Michigan research suggests that groups of neurons activated during prior learning keep humming, tattooing memories into your brain. U-M researchers have been studying how memories associated with a specific sensory event are formed and stored in mice. In a study conducted prior to the coronavirus pandemic and recently published in Nature Communications, the researchers examined how a fearful memory formed in relation to a specific visual stimulus. They found that not only did the neurons activated by the visual stimulus keep more active during subsequent sleep, sleep is vital to their ability to connect the fear memory to the sensory event. ....
IAR Systems introduces support for 64-bit Arm cores IAR Systems has announced that its C/C++ development toolchain IAR Embedded Workbench for Arm is now able to support 64-bit Arm cores including Arm Cortex-A35, Cortex-A53 and Cortex-A55. At a time when more applications are being based on 64-bit cores, specifically within low-power applications, deeply embedded and handheld devices, the Embedded Workbench provides customers with diverse microcontroller support as well as adapted licensing options to fit different organisations needs By supporting leading-edge designs needing the performance from 64-bit Arm cores, IAR Systems can enable its customers to make use of the toolchainâs optimisation technology also for 64-bit devices. In addition, integrated code analysis tools ensure code quality, and for simplified functional safety certification, a pre-certified version of the toolchain is available. ....
A new Northwestern Medicine study showed cognitive SuperAgers have resistance to the development of fibrous tangles in a brain region related to memory and which are known to be markers of Alzheimer's disease. ....
