Background: Endoscopic endonasal surgeries performed in areas involving the visual pathway are associated with postoperative dysfunction. We previously demonstrated that continued eye monitoring during surgery by flash evoked potential (FVEP) represents a good method to prevent/reduce deficit post-surgery. wondered whether FVEP may be more beneficial patients meningioma, strongly loss. The aim ...

Two experiments explore the color perception of objects in complex scenes. The first experiment examines the color perception of objects across variation in surface gloss. Observers adjusted the color appearance of a matte sphere to match that of a test sphere. Across conditions we varied the body color and glossiness of the test sphere. The data indicate that observers do not simply match the ...

We investigated the temporal properties of monocular and dichoptic cross-orientation masking (XOM) mediating suppressive or facilitatory cross-channel interactions between the neural detectors for the test and orthogonal mask stimuli. We measured the evolution of masking as a function of the duration of the test and mask stimuli to determine its time constant, and determined its dependence on s...

introduction: there has been an increasing interest in studies dealing with the relationship between mental disorders and color preference. this study was tailored to evaluate color preference or rejection in schizophrenic and normal subjects. materials and method: color preference and rejection of 58 patients with dsm-iv diagnosis of schizophrenia were compared with those of 52 normal subjects...

The test parameters were selected as a direct result of a previous study.1 That work involved five Liquid Crystal Display (LCD) projectors and two projectors based on Digital Light ProcessingTM technology. The sample size for this test was increased to seven LCD projectors and nine DLPTM projectors. Like the previous work, this study was supported by Texas Instruments Incorporated (TI). TI pers...

the color images raise the level of educational by providing more detailed information; therefore, these images are believed to be effective in gaining a deeper understanding of the lessons. moreover, proper lighting enhances students’ learning and performance. this study aimed at assessing the impact of training color and light materials on elementary school girls’ attention and learning in pe...
