A new set of META-BRAIN experiments took place in October at the coordinating institution, IDIBAPS, in Barcelona. Researchers Elric Zhang from ETH Zurich and Nathalia Cancino from IDIBAPS collaborated to conduct a series of experiments aimed at reaching the project milestone, “Successful Modulation of Emergent Activity”.
The goal of these experiments was to modulate cerebral cortex activity by activating nanoparticles with magnetic fields. The process involved first recording cortical activity with black platinum electrodes, then introducing nanoparticles, and finally activating them using magneting fields. This approach led to positive and observable changes in neuronal activity, suggesting a favourable initial response.
According to Elric Zhang: “The experiments went extremely well. We were able to controllably upregulate brain activity with the particles and magnetic fields and return activity to baseline levels once the magnet was removed. These results represent an improvement over our previous experiments and are a promising indication that our continued work on particle development and refined experimental protocols for brain slices is yielding positive progress“.
