Brain activity before the task predicts face-name memory

What is it about?

Why do some people remember face-name pairs better than others? This study looked at whether resting brain activity, measured before any memory task began, was linked to later performance on a face-name associative memory test. The findings showed that spontaneous gamma-band EEG activity was related to delayed recognition performance. In particular, higher frontal and temporal high-gamma power was associated with better memory performance, while posterior high-gamma power showed the opposite pattern. This suggests that individual differences in memory may partly reflect the brain’s resting-state activity before learning or retrieval even starts. The study highlights resting-state EEG as a useful way to understand the neural basis of associative memory in healthy adults.
