Journal ArticleDOI
Coinciding early activation of the human primary visual cortex and anteromedial cuneus
TL;DR: Results show that visual stimuli activate two cortical areas right from the beginning of the cortical response, and suggest that the anteromedial cuneus has the temporal position needed to interact with the primary visual cortex V1 and thereby to modify information transferred via V1 to extrastriate cortices.
Journal ArticleDOI
Diffusion tensor imaging and tractography of distal peripheral nerves at 3 T
Jaana Hiltunen,Jaana Hiltunen,Taru Suortti,Sakari Arvela,Mika Seppä,Raimo Joensuu,Riitta Hari +6 more
TL;DR: The first DTI and tractography results of human distal peripheral nerves are presented, showing that DTI is a quantitative method that could provide useful information for the diagnosis and follow-up of nerve lesions, entrapments, and regeneration.
Journal ArticleDOI
Sensorimotor Cortex Localization: Comparison of Magnetoencephalography, Functional MR Imaging, and Intraoperative Cortical Mapping
Antti Korvenoja,Erika Kirveskari,Hannu J. Aronen,Sari Avikainen,Antti Brander,Juha Huttunen,Risto J. Ilmoniemi,Juha E. Jääskeläinen,Tero Kovala,Jyrki P. Mäkelä,Eero Salli,Mika Seppä +11 more
TL;DR: Although both MEG and functional MR imaging can provide useful information for neurosurgical planning, in the present study, MEG proved to be superior for locating the central sulcus.
Journal ArticleDOI
Three hands: Fragmentation of human bodily awareness
Riitta Hari,Riitta Hari,R. Hänninen,Timo Mäkinen,Veikko Jousmäki,Nina Forss,Mika Seppä,Oili Salonen +7 more
TL;DR: It is concluded that simultaneous mental contents about body scheme may be based on neural information extracted at considerably different times, resulting in fragmentation of bodily awareness.
Journal ArticleDOI
Three-dimensional integration of brain anatomy and function to facilitate intraoperative navigation around the sensorimotor strip.

TL;DR: The preoperative visualization of the functional anatomy of the sensorimotor strip assisted in designing the operational strategy, facilitated orientation of the neurosurgeon during the operation, and speeded up the selection of sites for intraoperative stimulation or mapping, thereby helping to prevent damage of eloquent brain areas during surgery.
