Autobiographical Memories & NeuroImaging

Can we capture self-related, inner thoughts? At first, mind-wandering was defined  as a spontaneous mentation independent of any external input. Sometimes the mind moves spontaneously from one thought to another, however at other times it keeps coming back to the same thought, drawn by a particular memory or an emotional experience.

The spatiotemporal analyses of fMRI and EEG are sensitive and powerful tools to characterize brain networks involved in autobiographical memory and other cognitive processes. 

  • self-consciousness
  • altered states of consciousness
  • episodic memories
  • sleep and dreams
  • electroencephalography (EEG)
  • functional magnetic resonance (fMRI)
