PURPOSE To evaluate de macular structural damage in Stargardt's disease by optical coherence tomography, correlating with visual acuity and disease duration. METHODS Patients with Stargardt's disease were included and submitted to visual acuity (logMAR) measurement and complementary examinations performed were color fundus photographs, fluorescein angiography and optical coherence tomography....

How does our brain detect changes in a natural scene? While changes by increments of specific visual attributes, such as contrast or motion coherence, can be signaled by an increase in neuronal activity in early visual areas, like the primary visual cortex (V1) or the human middle temporal complex (hMT+), respectively, the mechanisms for signaling changes resulting from decrements in a stimulus...

Recent studies show that facial information contained in visual speech can be helpful for the performance enhancement of audio-only blind source separation (BSS) algorithms. Such information is exploited through the statistical characterization of the coherence between the audio and visual speech using, e.g., a Gaussian mixture model (GMM). In this paper, we present three contributions. With th...

Despite immense variability across languages, people can learn to understand any human language, spoken or signed. What neural mechanisms allow people to comprehend language across sensory modalities? When people listen to speech, electrophysiological oscillations in auditory cortex entrain to slow ([Formula: see text]8 Hz) fluctuations in the acoustic envelope. Entrainment to the speech envelo...

background: cystoid macular edema (cme) is one of the most common and sight threatening complications of uveitis. intravitreal injection of corticosteroids and anti-vegf antibody are two routine options for treatment. objective: to compare the effects of intravitreal injections of bevacizumab and triamcinolone acetonide for the treatment of persistent macular edema in non-infectious uveitis. me...

The identification of the networks connecting brain areas and the understanding of their role in executing complex tasks is a crucial issue in cognitive neuroscience. In this study, specific visuomotor tasks were devised to reveal the functional network underlying the cooperation process between visual and motor regions. Electroencephalography (EEG) data were recorded from twelve healthy subjec...

The cerebral cortex of the cat contains between 1 and 2 dozen representations of the visual field with different functional specializations. Six visual field maps lie along both banks of the suprasylvian sulcus, lateral and anterior to the visual areas in the occipital cortex. We have studied single-unit receptive field properties and their global organization across the visual field in 2 of th...

Visual world studies show that upon hearing a word in target-absent visual context containing related and unrelated items, toddlers adults briefly direct their gaze toward phonologically before shifting semantically visually ones. We present neural network model processes dynamic unfolding phonological representations of words maps them to static internal lexical, semantic, representations. The...
