The full functioning of the visual system may be threatened by various pathological conditions - genetic, environmental, infectious, neurological, metabolic - throughout life, in childhood, or in aging. Instruments to evaluate this functioning in humans may be behavioral or electrophysiological. A characteristic of these instruments is that they are non-invasive and, based on information …

Natural visual stimuli have characteristics for which the visual system is adapted and optimized. Natural colours, for example, are more frequent in the blue-yellow axis and represent only a small part of all the colours we can see. This project aims to explore the use of new colour vision tests based on natural stimuli obtained from spectral images of natural scenes and to use neural net…
The present proposal describes scientific activities for a visiting researcher with the Vision Laboratory in the Institute of Psychology at the University of São Paulo (USP) as the host institution for the visit of Dr. Mirella Barboni, associate scientist in the Department of Ophthalmology at Semmelweis University of Budapest in Hungary. The main objectives of the visit are to strengthen …
Zika virus (ZIKV) is an emerging virus in Brazil, which can lead to the development of a rash illness, often associated with low-grade fever, fatigue, myalgia and conjunctivitis. The ZIKV is also related to severe neurological complications such as Guillain-Barré syndrome, and fetal abnormalities such as microcephaly. However, the crucial risk factors to the development of these severe ma…

The clinical term albinism refers to the set of genetically heterogeneous diseases associated with the decrease or absence of melanin production (RIBEIRO, 2019; BAKKER et al., 2022). Hypopigmentation occurs in the eyes and/or skin and hair, together with the abnormal development of the visual system (SANO, 2017; SIMEONOV et al., 2013). The different types of albinism are categorized genot…
Melanopsin (Opn4) is a photopigment composed of vitamin A and a member of the receptors coupled to the G protein present in the skin, heart and retina of vertebrate animals. Previous literature has demonstrated direct involvement in the synchronization of the circadian rhythm, reflexes of pupil, melatonin suppression and other light regulation activities. More specifically, it works by me…

Snakes have high ecophysiological diversity, with different circadian rhythms and the use of different habitats, which is reflected in important variations in retinal structures. The retina is organized into layers of cells and nerve plexuses that process visual information. The types and organization of retinal neurons vary between species. In snakes, some studies have described photorec…
Duchenne muscular dystrophy (DMD) is an X-linked genetic disease resulting from mutations or deletions in the DMD gene. It affects the expression of dystrophin proteins (Dps) leading to severe muscle impairment. The Dps are also required for the proper functioning of the central nervous system (CNS). The retina and the brain cells express at least four types of Dps. Previous studies showe…

The visual system of snakes has phylogenetic and ecological variations related to their habits and activity patterns. Nocturnal species have typical duplex retinas, with rods and cones, while diurnal species have pure cone retinas, with no rod-like photoreceptors. Three opsin genes are expressed in retinas of most species, the rhodopsin gene RH1 expressed in rods and the cone opsin genes …
Electroretinography (ERG) is a non-invasive procedure which allows recording of electrical activity of the retina. It has been used to evaluate the different cellular circuits involved in visual processing at the retinal level, and has been used to elucidate the pathophysiological mechanisms in glaucoma disease. The aim of this proposal is to use ERG-based techniques to evaluate (1) the e…
The current study intends to evaluate several manifestations of anxiety in children and adolescents with Autistic Spectrum Disorder, such as physiological and biological measures, cognitive and behavioral symptoms and sleep and activity patterns. Four groups will be tested: two experimental groups of children with ASD with and without anxiety and two control groups of typically developing…
