Frequency tagging based on fast periodic visual stimulation (FPVS) provides a window into ongoing visual and cognitive processing and can be leveraged to measure rule learning and high-level categorization. In this talk, I will present data demonstrating highly proficient categorization as living and non-living in preschool children, and characterize the development of this ability during infancy. In addition to associating cognitive functions with development, an intriguing question is whether frequency tagging also captures enduring individual differences, e.g. in general cognitive abilities

The brain continuously receives vast amounts of information from the rest of the body and the environment, only a fraction of which can be consciously processed and stored in memory. It is believed that hippocampal sharp-wave ripples tag memories that are relevant and should be remembered (Yang et al 2024). However, this selection of relevant information must occur already during sensory processing to avoid overloading the system with irrelevant information. The hypothesis of this project is that short bursts of high gamma activity, referred to as cortical ripples to distinguish them from hipp
