The“Micro-Nano Sensing Technology”creative research group of NSFC from the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences, led by Professor CAI Xinxia, has developed a new method for fabricating high-precision, low-curvature microelectrode arrays (MEAs). The MEAs are designed for recording neuronal activities in brain's deep, small volume region. Published in the Microsystems & Nanoengineering on October 14, the study implanted the low-curvature MEAs into the ventral tegmental area (VTA) of rats, employing a modified T-maze to highlight the VTA's important role in reward processing and spatial information coding during goal-directed navigation.

The“Micro-Nano Sensing Technology” creative research group of NSFC from the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences, led by Professor CAI Xinxia, has made a breakthrough in brain-computer interface technology. The team developed a novel drug-loaded hydrogel-coated microelectrode array (MEA), which allows for long-term, high-quality detection of neural activity. The study was published in the journal Biosensors and Bioelectronics​.

A large-scale space-air-ground integrated scientific experiment, part of the "BeiDou-enabled Remote Sensing Application Pilot Program," was carried out from July 20 to August 15 at the Yellow River Delta National Nature Reserve.
