OBJECTIVES To determine the behavior of the visual cerebral cortex during the photo stimulation in the dissociated strabismus. MATERIAL AND METHODS We elaborated a digital cerebral mapping using the international 10-20 system with 21 electrodes and an option of a register of 32 channels with established parameters in every period (printed and with pulse(More)
In this article, several advanced connected transformations from mathematical morphology for computational neuroanat-omy applications are developed. In particular, brain is separated from the skull in MRI T 1 using morphological connected openings. The use of connected transformations allow the preservation of regions, without introduce new information. As(More)
In this paper a methodology to restore gray scale images with pixels polluted by random impulsive noise is presented. Noise is discovered using a criterion based on the white top-hat by reconstruction. Pixels detected as corrupted are restored using an iterative morphological algorithm built with extensive and antiex-tensive morphological transformations.(More)

A composition of the viscous opening and the lower leveling is introduced to extract brain in magnetic resonance imaging T1. The innovative transformation disconnects chained components and has better control on the reconstruction process of the marker inside of the original image. However, the sequential operator requires setting several parameters, making(More)
BACKGROUND We undertook this study to determine the cortical alterations related to the origin of dissociated deviation. METHODS This was a prospective, descriptive and observational study that included 10 children with diagnosis of dissociated horizontal deviation, without previous evidence of neuronal damage. Manual, cerebral and ocular dominance were(More)
pecializados llega a ser hasta de 73%, de los cuales el diag-nóstico integral es realizado de manera multidisciplinaria demostrándose compromiso a nivel cerebral hasta en 63% (1). Las causas etiológicas de las parálisis oculomotoras se registran por trauma craneal en 20%, vasculares en 17%, neoplásicas en 14%, aneurismas en 7%, otras en 15% e(More)
