Hearing aids (HAs) are an effective strategy for auditory rehabilitation in patients with peripheral hearing deficits. Yet, the neurophysiological mechanisms behind HA use are still unclear. Thus far, most studies have focused on changes in the audit

Functional magnetic resonance imaging (fMRI) has just completed 20years of existence. It currently serves as a research tool in a broad range of human brain studies in normal and pathological conditions, as is the case of epilepsy. To date, most fMRI

Generalized relative entropy in functional magnetic resonance imaging

Autor: Marcio Sturzbecher, Ubiraci P. C. Neves, Brenno Caetano Troca Cabella, Dráulio Barros de Araújo

Publikováno v: Physica A: Statistical Mechanics and its Applications. 388:41-50

The generalized Kullback–Leibler distance D q ( q is the Tsallis parameter) is shown to be an useful measure for analysis of functional magnetic resonance imaging (fMRI) data series. This generalized form of entropy is used to evaluate the “dista

Publikováno v: Physics in Medicine and Biology. 54:161-174

Functional magnetic resonance imaging (fMRI) data analysis has been carried out recently in the framework of information theory, by means of the Shannon entropy. As a natural extension, a method based on the generalized Tsallis entropy was developed

The Kullback-Leibler distance (or relative entropy) is applied in the analysis of functional magnetic resonance (fMRI) data series. Our study is designed for event-related (ER) experiments, where a brief stimulus is presented and a long period of res

Functional MRI (fMRI) data often have low signal-to-noise-ratio (SNR) and are contaminated by strong interference from other physiological sources. A promising tool for extracting signals, even under low SNR conditions, is blind source separation (BS
