Smoothing and cluster thresholding for cortical surface-based group analysis of fMRI data.

by Donald J Hagler Jr , ⁎ Ayse , Pinar Saygin , Martin I Sereno - Neuroimage , 2006
"... Cortical surface-based analysis of fMRI data has proven to be a useful method with several advantages over 3-dimensional volumetric analyses. Many of the statistical methods used in 3D analyses can be adapted for use with surface-based analyses. Operating within the framework of the FreeSurfer soft ..."

Encoding activity in the medial temporal lobe examined with anatomically constrained fMRI analysis

by Paul J. Reber, Eric C. Wong, Richard B. Buxton - Hippocampus 2002
"... ABSTRACT: Functional neuroimaging studies have produced a sizable number of observations of increased activity in the human medial tem-poral lobe (MTL) during encoding of novel memories. The studies have suggested possible functional specialization within the anatomical com-ponents of the MTL (hippo ..."

resonance imaging MRI to constrain the analysis of functional magnetic resonance imaging (fMRI) data, for independent assessment of functional activity change in each component of the MTL. With this method, increased activity was detected throughout the MTL in a group of participants (n 5) who encoded

Functional Subdivision of Group-ICA Results of fMRI Data Collected during Cinema Viewing

by Siina Pamilo, Sanna Malinen, Yevhen Hlushchuk, Pia Tikka, Riitta Hari , 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-course estimates. Here group-ICA was applied at four di ..."

Categorized EEG Neurofeedback Performance Unveils Simultaneous fMRI Deep Brain Activation

by Sivan Kinreich, Ilana Podlipsky, Talma Hendler
"... Abstract. Decades of Electroencephalogram-NeuroFeedback (EEG-NF) practice have proven that people can be effectively trained to selectively regulate their brain activity, thus potentially improving performance. A common protocol of EEG-NF training aims to guide people via a closedloop operation shif ..."

into responders and non-responders to the EEG-NF practice via a temporal signature of T/A continuous modulation. Comparing the two groups along with their parasympathetic Heart-Rate reactivity profile verified the relaxed state of the responders. Projection of responders variations in the T/A power to the fMRI

r Human Brain Mapping 31:1512–1531 (2010) r A Parametric Empirical Bayesian Framework for fMRI-Constrained MEG/EEG Source Reconstruction

by Richard N. Henson, Guillaume Fl, Karl J. Friston, Jérémie Mattout
"... Abstract: We describe an asymmetric approach to fMRI and MEG/EEG fusion in which fMRI data are treated as empirical priors on electromagnetic sources, such that their influence depends on the MEG/ EEG data, by virtue of maximizing the model evidence. This is important if the causes of the MEG/ EEG s ..."

, from a group analysis of different individuals. We evaluate the ensuing scheme with MEG and EEG data recorded simultaneously from 12 participants, using the same face-processing paradigm under which independent fMRI data were obtained. Because the fMRI priors become part of the generative model, we use

Natural patterns of activity and long-term synaptic plasticity.

by Ole Paulsen , Terrence J Sejnowski - Curr. Opin. , 2000
"... Long-term potentiation (LTP) of synaptic transmission is traditionally elicited by massively synchronous, high-frequency inputs, which rarely occur naturally. Recent in vitro experiments have revealed that both LTP and long-term depression (LTD) can arise by appropriately pairing weak synaptic inpu ..."

on dendrites. Third, a specific temporal pattern of activity -postsynaptic bursting -accompanies synaptic potentiation in adults. Introduction Acts of recollection, as they occur in experience, are due to the fact that one movement has by nature another that succeeds it in regular order. If this order

Film Excerpts Shown to Specifically Elicit Various Affects Lead to Overlapping Activation Foci in a Large Set of Symmetrical Brain Regions in Males

by Sherif Karama, Jorge Armony, Mario Beauregard
"... While the limbic system theory continues to be part of common scientific parlance, its validity has been questioned on multiple grounds. Nonetheless, the issue of whether or not there exists a set of brain areas preferentially dedicated to emotional processing remains central within affective neuros ..."

, the involvement of overlapping areas for various emotion conditions in keeping with the neural reference space for emotion, would serve as valuable confirmatory evidence. Here, using fMRI, 20 young adult men were scanned while viewing validated neutral and effective emotion-eliciting short film excerpts shown

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

by Robert Boldt, Sanna Malinen, Pia Tikka, Petri Savolainen, Riitta Hari - One , 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 sounds in a continuous audio drama designed for blind ..."
