Previous electrophysiological studies have identified a "voice specific response" (VSR) peaking around 320 ms after stimulus onset, latency markedly longer than the 70 needed to discriminate living from non-living sound sources and 150 200 for processing of voice paralinguistic qualities. In present study, we investigated whether an early difference between non-voice stimuli could be observed. ERPs were recorded 32 healthy volunteers who listened long three categories - voices, bird songs...

Abstract This investigation examined the neural and personality correlates of processing infant facial expressions in mothers with substantiated neglect a child under 5 years old. Event-related potentials (ERPs) were recorded from 14 neglectful control as they viewed categorized pictures cries, laughs, neutral faces. Maternal self-reports anhedonia empathy also completed. Early (negative occipitotemporal component peaking at around 170 ms on scalp [N170] positive electrical potential about...

Developmental dyslexia is one of the most prevalent learning disabilities, thought to be associated with dysfunction in neural systems underlying typical reading acquisition. Neuroimaging research has shown that readers exhibit regional hypoactivation left hemisphere nodes, relative control counterparts. This evidence, however, comes from studies have focused only on isolated aspects reading. The present study aims characterize for main processes involved successful reading: phonological,...

The present experiment investigates the input coding mechanisms of 3 common printed characters: letters, numbers, and symbols. Despite research in this area, it is yet unclear whether identity these elements processed through same or different brain pathways. In addition, some computational models propose that position-in-string responds to general flexible visual system are not character-specific, whereas others suggest position letters specific processes from those guide assignment other...

Over the last few decades, wine makers have been producing wines with a higher alcohol content, assuming that they are more appreciated by consumers. To test this hypothesis, we used functional magnetic imaging to compare reactions of human subjects different types wine, focusing on brain regions critical for flavor processing and food reward. Participants were presented carefully matched pairs high- low-alcohol content red wines, without informing them any attributes. Contrary expectation,...

<title>Abstract</title> Are an individual’s first (L1) and second (L2) languages represented in shared or distinct brain territories? Using intraoperative electrical stimulation mapping (ESM) two Basque-Spanish bilinguals with non-growing lesions—thus avoiding confounding effects of adaptive plasticity—this study identified language representations within the left temporal lobe. Stimulation posterior anterior superior gyri induced language-selective aphasias, whereas mid-temporal region...

Abstract Wine tasting is a very complex process that integrates combination of sensation, language, and memory. Taste smell provide perceptual information that, together with the semantic narrative converts flavor into words, seem to be processed differently between sommeliers naïve wine consumers. We investigate whether sommeliers' experience shapes only chemosensory processing, as has been previously demonstrated, or if it also modulates way in which taste olfactory circuits interact...

Picture naming tasks are currently the gold standard for identifying and preserving language-related areas during awake brain surgery. With multilingual populations increasing worldwide, patients frequently need to be tested in more than one language. There is still no reliable testing instrument, as available batteries have been developed specific languages. Heterogeneity selection criteria stimuli leads differences, example, size, color, image quality, even names associated with pictures,...

Abstract Words representing objects (nouns) and words actions (verbs) are essential components of speech across languages. While there is evidence regarding the organizational principles governing neural representation nouns verbs in monolingual speakers, little known about how this knowledge represented bilingual brain. To address gap, we recorded neuromagnetic signals while highly proficient Spanish–Basque bilinguals performed a picture-naming task tracked brain oscillatory dynamics...

Different kinds of known faces activate brain areas to dissimilar degrees. However, the tuning type knowledge, and temporal course activation, each area have not been well characterized. Here we measured, with functional magnetic resonance imaging, activity elicited by unfamiliar, visually familiar, personally-familiar faces. We assessed response amplitude duration using flexible hemodynamic functions, as face type, regions within processing system. Core (occipital fusiform areas) responded...

Abstract Recent evidence suggests that damage to the language network triggers its functional reorganization. Yet, spectro‐temporal fingerprints of this plastic rearrangement and relation anatomical changes is less well understood. Here, we combined magnetoencephalographic recordings with a proxy measure white matter investigate oscillatory activity supporting plasticity structural reshaping. First, cortical dynamics were acquired in group healthy controls during object action naming....

Abstract The maternal brain undergoes adaptations to sensitive caregiving that are critical for infant well-being. We investigated structural alterations associated with neglectful and their effects on mother–child interactive behavior. High-resolution 3D volumetric images were obtained 25 (NM) 23 non-neglectful control (CM) mothers. Using voxel-based morphometry, we compared differences in gray white matter (GM WM, respectively) volume. Mothers completed an empathy scale participated...

Recent evidence suggests that the presence of brain tumors (e.g., low-grade gliomas) triggers language reorganization. Neuroplasticity mechanisms called into play can transfer linguistic functions from damaged to healthy areas unaffected by tumor. This phenomenon has been reported in monolingual patients, but much less is known about neuroplasticity bilingual brain. A central question whether processing a first or second involves same different cortical territories and damage results diverse...

Abstract The role of the left temporoparietal cortex in speech production has been extensively studied during native language processing, proving crucial controlled lexico-semantic retrieval under varying cognitive demands. Yet, its bilinguals, fluent both and second languages, remains poorly understood. Here, we employed continuous theta burst stimulation to disrupt neural activity posterior middle-temporal gyrus (pMTG) angular (AG) while Italian–Friulian bilinguals performed a cued...

Abstract Research on the neural imprint of dual-language experience, crucial for understanding how brain processes dominant and non-dominant languages, remains inconclusive. Conflicting evidence suggests either similarity or distinction in processing, with implications bilingual patients tumors. Preserving functions after surgery requires considering pre-diagnosis neuroplastic changes. Here, we combine univariate multivariate fMRI methodologies to test a group healthy Spanish-Basque...

Results illustrating an atypical neural processing in the early and late differentiation of infant faces have been obtained with neglectful mothers. The present study explores whether a different pattern response is observed when using non-infant affective pictures. We examined event-related evoked potentials induced delta, theta alpha activity 14 mothers control elicited while categorizing positive, negative neutral pictures from International Affective Picture System. Self-reports...
