Marcação e recaptura da curimbatá-pioa (Prochilodus costatus) em um afluente do rio São Francisco e avaliação da necessidade da transposição de peixes na UHE Gafanhoto

Abstract

This study was undertaken to verify whether different output variables or biosignals, measured during performance of a cognitive task, manifest common dynamical properties. Nonlinear properties of both response times ({RTs}) and electroercephalograms ({EEG}) were tested. We asked subjects to generate mental images of actions following of auditorily presentation simple phrases suggesting the action. Analysis of {RT} series combined from many subjects and of {EEG} records from single subjects clearly manifested self-similarity and chaotic dynamics that provide insights into the self-organization of the brain/behavioral system.
