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 runnin...

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 re...

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 design...

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.

Mice study finds altered brain connectivity after prolonged anesthesia Prolonged anesthesia, also known as medically induced coma, is a life-saving procedure carried out across the globe on millions of patients in intensive medical care units every year. But following prolonged anesthesia--which takes the brain to a state of deep unconsciousness beyond short-term anesthesia for surgical procedures--it is common for family members to report that after hospital discharge their loved ones were not quite the same. "It is long known that ICU survivors suffer lasting cognitive impairment, such as c...
