Motor imagery in response to fake feedback measured by functional near-infrared spectroscopy


Holper, L; Wolf, M (2010). Motor imagery in response to fake feedback measured by functional near-infrared spectroscopy. NeuroImage, 50(1):190-197.

Abstract

The objective of this study was to describe brain oxygenation patterns during motor imagery (MI) in response to feedback using functional near-infrared spectroscopy (fNIRS). fNIRS was recorded over the primary motor cortex in 15 healthy subjects using a right hand motor task during four fake feedback conditions: MI without feedback (MI(0)), MI with positive (MI(+)) and negative feedback (MI(-)) and during actual movement execution (ME) as control task. Behavioral data were collected using the Edinburgh Handedness Inventory (EHI) and The Kinesthetic and Visual Imagery Questionnaire (KVIQ-10). We observed inter-condition differences and inter-subject variability in signal amplitude with larger O(2)Hb concentration changes both in response to MI(+) (0.154+/-0.067 muM) and MI(-) (0.129+/-0.074 muM) as compared to MI(0) (0.109+/-0.024 muM) and ME (0.210+/-0.013 muM). We present fNIRS data of MI performance in response to different feedback conditions indicating that there exist distinct oxygenation patterns. These data may contribute to the development of fNIRS controlled feedback systems.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
