Research is being conducted on the neural correlates of semantic memory, including its relationship to the hippocampus and prefrontal cortex, in various contexts such as autism spectrum disorder, creative ability, and aging. The studies are exploring how semantic memory is supported by different brain regions and processes, including event-related potentials and neural oscillations. The findings appear to be related to episodic memory retrieval, concept generalization, and long-term memory, although the specific focus and outcomes of the research are not clearly defined.
