Listening to an audio drama activates two processing networks, one for all sounds, another exclusively for speech.

Autor: Robert Boldt, Sanna Malinen, Mika Seppä, Pia Tikka, Petri Savolainen, Riitta Hari, Synnöve Carlson

Publikováno v: PLoS ONE, Vol 8, Iss 5, p e64489 (2013)

Earlier studies have shown considerable intersubject synchronization of brain activity when subjects watch the same movie or listen to the same story. Here we investigated the across-subjects similarity of brain responses to speech and non-speech sou

Publikováno v: PLoS ONE, Vol 7, Iss 7, p e42000 (2012)

Independent component analysis (ICA) can unravel functional brain networks from functional magnetic resonance imaging (fMRI) data. The number of the estimated components affects both the spatial pattern of the identified networks and their time-cours

Precuneus functioning differentiates first-episode psychosis patients during the fantasy movie Alice in Wonderland

Autor: Riitta Hari, Tuula Kieseppä, Jaana Suvisaari, Eva Rikandi, Siina Pamilo, Mika Seppä, Teemu Mäntylä, Tuukka T. Raij

Publikováno v: Psychological medicine. 47(3)

BackgroundWhile group-level functional alterations have been identified in many brain regions of psychotic patients, multivariate machine-learning methods provide a tool to test whether some of such alterations could be used to differentiate an indiv

High-quality two-stage resampling for 3-D volumes in medical imaging

Autor: Mika Seppä

Publikováno v: Medical Image Analysis. 11:346-360

This paper introduces a simple method of two-stage resampling where Fourier-domain up-sampling is followed by traditional resampling. Practical aspects as well as efficient implementation techniques are considered. A new version of pruned FFT algorit

A correlation-based method for extracting subject-specific components and artifacts from group-fMRI data

Autor: Mika Seppä, Jaakko Hotta, Sanna Malinen, Siina Pamilo

Publikováno v: The European journal of neuroscience. 42(9)

We present a simple but effective correlation-based method (maxCorr) for extracting subject-specific components from group-fMRI data. The method finds signal components that correlate maximally with the data set of one subject and minimally with the

Three hands: fragmentation of human bodily awareness

Autor: Mika Seppä, R. Hänninen, Oili Salonen, Nina Forss, Timo Mäkinen, Veikko Jousmäki, Riitta Hari

Publikováno v: Neuroscience Letters. 240:131-134

We describe patient E.P. who occasionally perceives a 'ghost' hand which copies the previous positions of the left hand with a 0.5-1 min time lag, but follows the movement patterns of the right hand. The symptoms started after an operation of a ruptu
