- An Investigation of RSN Frequency Spectra Using Ultra-Fast Generalized Inverse Imaging
Rasim Boyacioğlu
Radboud University Nijmegen, Donders Institute for Brain, Cognition and Behaviour Nijmegen, Netherlands
Front Hum Neurosci 7:156. 2013
..Respiration related signal changes are, on the other hand, removed from the data without the need for external physiological recordings. We have observed that the variance over the subjects is higher than the variance over RSNs...
- Functional connectivity during light sleep is correlated with memory performance for face-location associations
Eelco V van Dongen
Radboud University Nijmegen, Donders Institute for Brain, Cognition and Behaviour, Nijmegen, The Netherlands
Neuroimage 57:262-70. 2011
..Thus, our study provides correlational evidence for the behavioral relevance of specific medial prefrontal and hippocampal interactions with the fusiform gyrus during light sleep...
