In the mature adult brain, there are voice selective regions that especially tuned to familiar voices. Yet, little is known about how infant's brain treats such information. Here, we investigated, using electrophysiology and source analyses, newborns process their mother's compared with of a stranger. Results suggest that, shortly after birth, distinctly at an early preattentional level later presumably cognitive level. Activation sources revealed exposure maternal elicited language-relevant...
Abstract Our ability to discriminate and recognize human voices is amongst the most important functions of auditory system. The current study sought determine whether electrophysiological markers could be used as objective measures voice familiarity, by looking at responses [mismatch negativity (MMN) P3a] when infrequent stimulus presented a familiar opposed an unfamiliar voice. Results indicate that MMN elicited greater than FCz. also produced P3a wave triggered Fz. As both were...
This study assessed whether the neonatal brain recruits different neural networks for native and non-native languages at birth. Twenty-seven one-day-old full-term infants underwent functional near-infrared spectroscopy (fNIRS) recording during linguistic non-linguistic stimulation. Fourteen newborns listened to stimuli (native language stories) 13 were exposed conditions played in reverse). Comparisons between left right hemisphere oxyhemoglobin (HbO2) concentration changes over temporal...
Abstract Continuous brain imaging techniques can be beneficial for the monitoring of neurological pathologies (such as epilepsy or stroke) and neuroimaging protocols involving movement. Among existing ones, functional near‐infrared spectroscopy (fNIRS) electroencephalography (EEG) have advantage being noninvasive, nonobstructive, inexpensive, yield portable solutions, offer complementary electrical local hemodynamic activities. This article presents a novel system with 128 fNIRS channels 32...
In this paper, we present the design and implementation of a wireless wearable electronic system dedicated to remote data recording for brain monitoring. The reported is used a) simultaneous near-infrared spectrometry (NIRS) scalp electro-encephalography (EEG) noninvasive monitoring b) intracerebral EEG (icEEG) invasive Bluetooth dual radio links were introduced these recordings. Bluetooth-based device was embedded in multichannel EEG-NIRS easy portability long-term On other hand, 32-channel...
Fragile X Syndrome (FXS) is the most common monogenic form of intellectual disability and one few known causes autism. It caused by a trinucleotide repeat expansion in FMR1 ('Fragile Mental Retardation 1') gene, which prevents expression 'Fragile Protein' (FMRP). In FXS, absence FMRP leads to altered structural functional development synapse, while preventing activity-based synapse maturation synaptic pruning, are essential for normal brain cognitive development. Possible impairments...
Summary Purpose: To investigate spatial and metabolic changes associated with frontal lobe seizures. Methods: Functional near‐infrared spectroscopy combined electroencephalography (EEG‐fNIRS) recordings of patients confirmed nonlesional refractory epilepsy (FLE). Key Findings: Eighteen seizures from nine (seven male, mean age 27 years, range 13–46 years) drug‐refractory FLE were captured during EEG‐fNIRS recordings. All coupled significant hemodynamic variations that greater electroclinical...
Patients with congenital heart disease (CHD) requiring cardiac surgery in infancy are at high risk for neurodevelopmental impairments. Neonatal imaging studies have reported disruptions of brain functional organization before surgery. Yet, the extent to which network alterations present after repair remains unexplored. This preliminary study aimed investigating cortical connectivity 4-month-old infants repaired CHD, using resting-state near-infrared spectroscopy (fNIRS). After fNIRS signal...
In the past decades, multiple studies have been interested in developmental patterns of visual system healthy infants. During first year life, differential maturational changes observed between Magnocellular (P) and Parvocellular pathways. However, few investigated P M development infants born prematurely. The aim present study was to characterize differences preterm fullterm through a critical period maturation: life. Using cross-sectional design, high-density electroencephalogram (EEG)...
Functional near-infrared spectroscopy (fNIRS) is a non-invasive imaging technique that elicits growing interest for research and clinical applications. In the last decade, efforts have been made to develop mathematical framework in order image effective sources of hemoglobin variations brain tissues. Different approaches can be used impose additional information or constraints when reconstructing cerebral images an ill-posed problem. The goal this study compare performance limitations...
Fragile X Syndrome (FXS) is a neurodevelopmental genetic disorder associated with cognitive and behavioural deficits. In particular, neuronal habituation processes have been shown to be altered in FXS patients. Yet, while such deficits primarily explored using auditory stimuli, less known the visual modality. Here, we investigated putative alteration of repetition suppression faces patients compared controls that had same age distribution. Electroencephalographic (EEG) signals were acquired...
Fragile X syndrome (FXS) is a neurodevelopmental genetic disorder causing cognitive and behavioural deficits. Repetition suppression (RS), learning phenomenon in which stimulus repetitions result diminished brain activity, has been found to be impaired FXS. Alterations RS have associated with problems FXS; however, relations between intellectual functioning not yet elucidated. EEG was recorded 14 FXS participants 25 neurotypical controls during an auditory habituation paradigm using...
Neurodevelopmental disabilities affect up to 50% of survivors congenital heart disease (CHD). Language difficulties are frequently identified during preschool period and can lead academic, social, behavioral, emotional difficulties. Structural brain alterations associated with poorer neurodevelopmental outcomes in patients CHD infancy, childhood, adolescence. However, evidence is lacking about the functional activity children its relationship neurodevelopment. This study therefore aimed...
