Journal ArticleDOI

TL;DR: The findings suggest that the intestinal microbiome is altered in PD and is related to motor phenotype, and the suitability of the microbiome as a biomarker is warranted.
Journal ArticleDOI
Processing of novel sounds and frequency changes in the human auditory cortex: Magnetoencephalographic recordings
Kimmo Alho,István Winkler,István Winkler,Carles Escera,Minna Huotilainen,Minna Huotilainen,Juha Virtanen,Juha Virtanen,Iiro P. Jääskeläinen,Iiro P. Jääskeläinen,Eero Pekkonen,Eero Pekkonen,Risto J. Ilmoniemi +12 more
TL;DR: Source localization for the MEG counterpart of P3a (P3am) suggested that the auditory cortex in the superior temporal plane is involved in the neural network of involuntary attention switching to changes in the acoustic environment.
Journal ArticleDOI
Gut microbiota in Parkinson's disease: Temporal stability and relations to disease progression.
Velma T. E. Aho,Pedro A. B. Pereira,Sari Voutilainen,Lars Paulin,Eero Pekkonen,Petri Auvinen,Filip Scheperjans +6 more
TL;DR: In progression comparisons, differentially abundant taxa were inconsistent across methods and timepoints, but there was some support for a different distribution of enterotypes and a decreased abundance of Prevotella in faster-progressing patients.
Journal ArticleDOI
Combined mapping of human auditory EEG and MEG responses
Minna Huotilainen,István Winkler,István Winkler,Kimmo Alho,Kimmo Alho,Carles Escera,Juha Virtanen,Juha Virtanen,Risto J. Ilmoniemi,Iiro P. Jääskeläinen,Iiro P. Jääskeläinen,Eero Pekkonen,Eero Pekkonen,Risto Näätänen +13 more
TL;DR: It was found that the electric P50, N1 and MMN responses can to a considerable degree be explained by the sources of the corresponding magnetic responses, and source-current components not detectable by MEG were shown to contribute to the measured EEG signals.
Journal ArticleDOI
Mismatch Negativity in Aging and in Alzheimer’s and Parkinson’s Diseases
TL;DR: The present findings on PD are not as conclusive, although they tentatively suggest deteriorated automatic change detection, and the MMN appears to offer an objective tool for studying auditory processing and memory trace decay in different neurological disorders.
