Researchers, including those from the ESI, have presented new findings on stimulus processing in the brain in a study published in advance on nature.com. Their research marks a paradigm shift, moving away from the question “Which brain region is active?” toward the perspective “How is information organized in the brain?”
The study investigated how visual information is processed in the brain. To do this, two key types of signals were examined: first, so-called broadband signals, which are spread broadly across a frequency range, and second, so-called gamma oscillations, whose oscillations occur within a defined frequency range.
One objective of the study was to determine how these two types of signals encode information. The results revealed evidence of a fascinating interaction: the effects of broadband signals are particularly relevant immediately after stimulus exposure, as they combine stimulus information across multiple brain regions so efficiently that a higher information content is produced than would be the case if processed in individual brain regions.
