Torres F, Silva Filho M, Antunes C, Kalinine E, Antoniolli E, Portela L, et al.
Exp Neurol . 2009 Dec; 221(2):296-306. PMID: 19948169
Quinolinic acid (QA) is an N-methyl-D-aspartate receptor agonist that also promotes glutamate release and inhibits glutamate uptake by astrocytes. QA is used in experimental models of seizures studying the effects...

Doc Ophthalmol . 2009 Nov; 120(2):145-58. PMID: 19921295
We studied the contribution of retinal on and off-mechanisms in the multifocal electroretinogram (mfERG) by measuring responses to saw tooth stimuli. Six healthy subjects participated in this study. Rapid-on and...

Kremers J, Rodrigues A, de Lima Silveira L, Silva Filho M
Invest Ophthalmol Vis Sci . 2009 Sep; 51(1):577-87. PMID: 19737882
Purpose: To test the hypothesis that electroretinograms (ERGs) reflect luminance activity when measured at high temporal frequencies and chromatic activity when measured near 12 Hz. Methods: The authors measured the...

Mendes T, Almeida Sobrinho E, Rosa A, dos Anjos L, da Costa G, Souza G, et al.
Doc Ophthalmol . 2009 Jun; 119(2):145-55. PMID: 19536574
The objective of this study was to evaluate the visual loss due to dengue fever using retinal and cortical electrophysiology and retinal imaging. The participants were three female patients with...

Dyer M, Martins R, Silva Filho M, Muniz J, Silveira L, Cepko C, et al.
Proc Natl Acad Sci U S A . 2009 May; 106(22):8963-8. PMID: 19451636
Conserved developmental programs, such as the order of neurogenesis in the mammalian eye, suggest the presence of useful features for evolutionary stability and variability. The owl monkey, Aotus azarae, has...

Gomes B, Souza G, Lima M, Rodrigues A, Saito C, Silva Filho M, et al.
Vis Neurosci . 2008 Jul; 25(3):333-9. PMID: 18598404
The purpose of this work is to investigate the use of different forms of visual evoked potentials (VEPs) to measure color discrimination thresholds and to plot color discrimination ellipses (MacAdam,...

Souza G, Gomes B, Lacerda E, Saito C, Silva Filho M, Silveira L
Vis Neurosci . 2008 Mar; 25(3):317-25. PMID: 18321403
We investigated how the stimulation mode influences transient visual evoked potentials (tVEP) amplitude as a function of contrast of achromatic and isoluminant chromatic gratings. The chromatic stimulation probed only responses...

da Costa G, dos Anjos L, Souza G, Gomes B, Saito C, Pinheiro M, et al.
Environ Res . 2007 Sep; 107(1):98-107. PMID: 17889848
Amazonian gold mining activity results in human exposure to mercury vapor. We evaluated the visual system of two Amazonian gold miners (29 and 37 years old) by recording the transient...

Souza G, Gomes B, Saito C, Silva Filho M, Silveira L
Invest Ophthalmol Vis Sci . 2007 Jun; 48(7):3396-404. PMID: 17591914
Purpose: To compare the spatial luminance contrast sensitivity function (CSF) obtained with transient visual evoked potentials (VEPs) with that obtained with psychophysical measurements. Methods: The stimuli consisted of horizontal luminance...
