|Title:||Event-related brain potentials during a continuous performance test (CPT) task in normal children|
Maci as, E.R.
|Abstract:||Steady shear and rheo-optical experimental data measured in several micellar solutions, demonstrate the existence of a non-equilibrium critical point (necp) in the shear banding flow of wormlike micellar solutions by the following evidence: (1) the disappearance of the coexistence of two steady banded fluids at the necp, (2) the curves of the reduced shear stress versus reduced shear rate become anti-symmetric in the neighborhood of the non-equilibrium critical point; (3) flow birefringence increases considerably in the neighborhood of the necp; (4) the divergence of non-equilibrium thermodynamic properties (isothermal flow susceptibility and the normalized heat dissipation), as the necp is approached; and (5) the existence of a finite correlation dimension calculated from time analysis of birefringence data, and positive Lyapunov exponents, which are consistently smaller than the embedding dimension.The predictions of the BMP model follow these trends closely.

Event-related potentials (ERPs) during a CPT (X-AX) test were obtained in 16 healthy male students, with ages ranging from 9 to 11 years (X = 10.3). In grouped averaged ERPs, an endogenous slow positive potential was recorded in the first task (infrequent letter detection); maximum was at 460 msec with a slight lateralization tendency toward left parietal area. In the second task (target detection with an A as warning signal), an early (maximum at 330 msec) and more acute peak was detected without evidence of any lateralization. Results. Reaction times were significantly shorter for the second task. Electrophysiologic differences between both target conditions showed an early, remarkable, and statistically significant component located at the parietal area at 340 msec. Conclusions. These ERPs findings could be interpreted as correlates with working memory processes in children. Copyright " 2001 IMSS.
