Spatial frequency selectivity of the human visual cortex estimated with pseudo-random visual evoked cortical potential (VECP)
Martins I, Brasil A, Miquilini L, Goulart P, Herculano A, Silveira L, et al.
Vision Res . 2019 Oct; 165:13-21. PMID: 31610286
Single-cell recordings in the primary visual cortex (V1) show neurons with spatial frequency (SF) tuning, which had different responses to chromatic and luminance stimuli. Visually evoked cortical potential (VECP) investigations...

Mercury exposure of children living in Amazonian villages: influence of geographical location where they lived during prenatal and postnatal development
Freitas J, Lacerda E, Rodrigues Junior D, Corvelo T, Silveira L, Pinheiro M, et al.
An Acad Bras Cienc . 2019 Apr; 91(suppl 1):e20180097. PMID: 31017187
Introduction: In some Amazonian river basins, hair mercury concentration is above the recommended levels. We evaluated the influence of birth geographical location in the hair mercury level of Amazonian riverine...

Methylmercury alters the number and topography of NO-synthase positive neurons in embryonic retina: Protective effect of alpha-tocopherol
Sampaio G, Oliveira K, Kauffmann N, do Nascimento J, Souza G, Gomes B, et al.
Toxicol In Vitro . 2018 Aug; 53:89-98. PMID: 30075186
Vertebrate retina has been shown to be an important target for mercury toxicity and very studies have shown the effect of mercury on the retinal ontogenesis. The nitrergic system plays...

Barefoot Plantar Pressure Indicates Progressive Neurological Damage in Patients with Human T-Cell Lymphotropic Virus Type 1 Infection
Vasconcelos B, Souza G, Barroso T, Silveira L, Sousa R, Callegari B, et al.
PLoS One . 2016 Mar; 11(3):e0151855. PMID: 26998608
Background: The human T-Cell Lymphotropic Virus Type 1 (HTLV-1) is a retrovirus associated with neurological alterations; individuals with HTLV-1 infection may develop HTLV-1 associated myelopathy / tropical spastic paraparesis (HAM/TSP)....

Colour Vision Impairment in Young Alcohol Consumers
Brasil A, Castro A, Martins I, Lacerda E, Souza G, Herculano A, et al.
PLoS One . 2015 Oct; 10(10):e0140169. PMID: 26465148
Alcohol consumption among young adults is widely accepted in modern society and may be the starting point for abusive use of alcohol at later stages of life. Chronic alcohol exposure...

Optical coherence tomography and multifocal electroretinography of patients with advanced neovascular age-related macular degeneration before, during, and after treatment with ranibizumab
Almeida I, Almeida L, Almeida Sobrinho E, Gomes B, Souza G, Rosa A, et al.
Arq Bras Oftalmol . 2015 May; 78(2):105-9. PMID: 25945532
Purpose: To evaluate retinal morphology and function of patients with advanced neovascular age-related macular degeneration (AMD) before, during, and after treatment with ranibizumab. Methods: Twenty-one eyes diagnosed with advanced AMD...

The spatial properties of L- and M-cone inputs to electroretinograms that reflect different types of post-receptoral processing
Jacob M, Pangeni G, Gomes B, Souza G, Silva Filho M, Silveira L, et al.
PLoS One . 2015 Mar; 10(3):e0121218. PMID: 25785459
We studied the spatial arrangement of L- and M-cone driven electroretinograms (ERGs) reflecting the activity of magno- and parvocellular pathways. L- and M-cone isolating sine wave stimuli were created with...

Cortical responses elicited by luminance and compound stimuli modulated by pseudo-random sequences: comparison between normal trichromats and congenital red-green color blinds
Risuenho B, Miquilini L, Lacerda E, Silveira L, Souza G
Front Psychol . 2015 Feb; 6:53. PMID: 25674074
Conventional pattern-reversal visual evoked cortical potential (VECP) shows positivity for luminance and chromatic equiluminant stimuli while conventional pattern-onset VECP shows positivity for luminance pattern-onset and negativity for chromatic pattern-onset. We...

Low number of luminance levels in the luminance noise increases color discrimination thresholds estimated with pseudoisochromatic stimuli
Souza G, Malone F, Crawford T, Miquilini L, Salomao R, Guimaraes D, et al.
Front Psychol . 2015 Jan; 5:1291. PMID: 25566106
In pseudoisochromatic stimuli the presence of spatial and luminance noise forces the subject to discriminate the target from the background solely on the basis of chromaticity difference. Color-blind subjects may...

Alouatta trichromatic color vision: cone spectra and physiological responses studied with microspectrophotometry and single unit retinal electrophysiology
Silveira L, Saito C, Silva Filho M, Kremers J, Bowmaker J, Lee B
PLoS One . 2014 Nov; 9(11):e113321. PMID: 25405863
The howler monkeys (Alouatta sp.) are the only New World primates to exhibit routine trichromacy. Both males and females have three cone photopigments. However, in contrast to Old World monkeys,...
