This study aims to describe neurological, visual, and auditory findings in children whose mothers had confirmed Zika virus (ZIKV) infection during pregnancy, with most of these children not presenting congenital microcephaly; Methods: an observational, longitudinal, and prospective study was conducted in Rio de Janeiro, Brazil, from March 2015 to January 2017, involving children with in utero exposure to Zika virus, following from birth up to 30 months of age. Results: Of the 2882 pregnant women admitted, 116 had a suspected ZIKV infection, of whom 33 had laboratory confirmation. Only one child presented with congenital microcephaly. Despite this, neurodevelopment delay was observed in 36.4% of children evaluated, radiological abnormalities in 29.1%, auditory abnormalities in 8.3%, and ophthalmological abnormalities in 10%. Conclusions: Newborns of mothers with confirmed ZIKV infection during pregnancy may present with varying degrees of visual, auditory, and neurological impairment, despite the presence of congenital microcephaly.

Sensory areas exhibit modular selectivity to stimuli, but they can also respond to features outside of their basic modality. Several studies have shown cross-modal plastic modifications between visual and auditory cortices; however, the exact mechanisms of these modifications are yet not completely known. To this aim, we investigated the effect of 12 min of visual versus sound adaptation (referring to forceful application of an optimal/nonoptimal stimulus to a neuron[s] under observation) on the infragranular and supragranular primary visual neurons (V1) of the cat (Felis catus).

Prior researches on global-local processing have focused on hierarchical objects in the visual modality, while the real-world involves multisensory interactions. The present study investigated whether the simultaneous presentation of auditory stimuli influences the recognition of visually hierarchical objects. We added four types of auditory stimuli to the traditional visual hierarchical letters paradigm:no sound (visual-only), a pure tone, a spoken letter that was congruent with the required response (response-congruent), or a spoken letter that was incongruent with it (response-incongruent).

Background: According to the standard definition, a hallucination is 1) a perceptual experience occurring in the absence of a relevant perceptual object, 2) it has the sense of reality of a veridical perception, and 3) it is unwilled and not under voluntary control of the hallucinator. This definition is supposed to encompass all hallucinations, across mental disorders and experiential modalities.
Summary: In this article, we examine the standard definition's validity by comparing visual hallucinations in delirium and auditory verbal hallucinations (AVHs) in schizophrenia, focusing especially on the definition's second criterion, i.

During Pavlovian conditioning, Sign-Tracker (ST), Goal-Tracker (GT), and Intermediate (IN) phenotypes emerge, as characterized by the degree to which an individual attributes incentive salience to reward-associated cues. These operationally defined phenotypes differ in other respects: In human studies, STs tend to favor bottom-up attention, while GTs tend to favor top-down attention. There is some limited evidence that rats exhibit similar patterns during Pavlovian conditioning.
