2018 AANS Annual Scientific Meeting-545. Mesial temporal lobe and cingulate event-related potentials signal memory recall errors

545. Mesial temporal lobe and cingulate event-related potentials signal memory recall errors

Video Transcription

Video Summary

Dr. Hudgens discusses the topic of mesial temporal lobe and cingulate event-related potentials signaling memory recall errors. He explains that humans have a narrow field of view of roughly two degrees, highlighting the importance of what we focus on visually. Our brains have developed strategies to alert us to important events and errors, which require perception and awareness. The study conducted by Dr. Hudgens and his team using intracranial EEG showed that the neural generator for these signals may arise from mesial temporal lobe structures, which detect errors earlier than cingulate structures. Frontal cortex showed no discernible event-related potentials. Overall, the study suggests that learning from errors is a fundamental strategy in interacting with our environment. Credits are given to Dr. Grady, Tim Lucas, Dr. Hudgens' wife Justine, and Casey Halpern.
