Me, Myself, and I: Neural Activity for Self versus Other across Development

Solange Noémie Jeanne Denervaud

Although adults and children differ in self-vs.-other perception, a developmental perspective on this discriminative ability at the brain level is missing. This study examined neural activation for self-vs.-other in a sample of 39 participants spanning fou ...

The effects of war on Ukrainian research

Gaétan Jean A de Rassenfosse, Wolf-Hendrik Peter Uhlbach

The ongoing war in Ukraine has profoundly impacted the Ukrainian scientific community. Numerous researchers have either emigrated or transitioned to alternate professions. For those who remain in research, the destruction of civil infrastructure and psycho ...

The critical periods of cerebral plasticity: A key aspect in a dialog between psychoanalysis and neuroscience centered on the psychopathology of schizophrenia

Pierre Magistretti

Through research into the molecular and cellular mechanisms that occur during critical periods, recent experimental neurobiological data have brought to light the importance of early childhood. These have demonstrated that childhood and early environmental ...

Prenatal auditory experience and its sequelae

Lukas Vogelsang

Towards the end of the second trimester of gestation, a human fetus is able to register environmental sounds. This in utero auditory experience is characterized by comprising strongly low-pass-filtered versions of sounds from the external world. Here, we p ...

Rapid suppression and sustained activation of distinct cortical regions for a delayed sensory-triggered motor response

Wulfram Gerstner, Carl Petersen, Sylvain Crochet, Alireza Modirshanechi, Vahid Esmaeili, Samuel Pavio Muscinelli, Georgios Foustoukos, Keita Tamura, Yanqi Liu, Anastasiia Oryshchuk

The neuronal mechanisms generating a delayed motor response initiated by a sensory cue remain elusive. Here, we tracked the precise sequence of cortical activity in mice transforming a brief whisker stimulus into delayed licking using wide-field calcium im ...

Dysmaturation Observed as Altered Hippocampal Functional Connectivity at Rest Is Associated With the Emergence of Positive Psychotic Symptoms in Patients With 22q11 Deletion Syndrome

Dimitri Nestor Alice Van De Ville, Maude Schneider, Daniela Maria Zöller, Farnaz Delavari

BACKGROUND: Hippocampal alterations are among the most replicated neuroimaging findings across the psychosis spectrum. Moreover, there is strong translational evidence that preserving the maturation of hippocampal networks in mice models prevents the progr ...

Multilingual Training and Adaptation in Speech Recognition

Sibo Tong

State-of-the-art acoustic models for Automatic Speech Recognition (ASR) are based on Hidden Markov Models (HMM) and Deep Neural Networks (DNN) and often require thousands of hours of transcribed speech data during training. Therefore, building multilingual ...

LTP of inhibition at PV interneuron output synapses requires developmental BMP signaling

Ralf Schneggenburger, Denys Osypenko, Christopher Clark, Evan Dean Vickers

Parvalbumin (PV)-expressing interneurons (PV-INs) mediate well-timed inhibition of cortical principal neurons, and plasticity of these interneurons is involved in map remodeling of primary sensory cortices during critical periods of development. To assess ...

Music enhances structural maturation of emotional processing neural pathways in very preterm infants

François Lazeyras, Nicolas Kunz

Prematurity disrupts brain maturation by exposing the developing brain to different noxious stimuli present in the neonatal intensive care unit (NICU) and depriving it from meaningful sensory inputs during a critical period of brain development, leading to ...

Learning (Good Handwriting In Greek) By Teaching (A Humanoid Robot)

Wafa Monia Benkaouar Johal, Thibault Lucien Christian Asselborn, Thanasis Hadzilacos

We report on a follow-up study of the Co-Writer project at EPFL [1]; we confirm their findings, extend the applicability to another language with a different alphabet (Greek) and go into an in-depth qualitative study of the child-robot relationship. The co ...

Consensus guidelines for the use and interpretation of angiogenesis assays

Michele De Palma, Patrycja Nowak-Sliwinska, George Coukos, Elizabeth Anne Allen

The formation of new blood vessels, or angiogenesis, is a complex process that plays important roles in growth and development, tissue and organ regeneration, as well as numerous pathological conditions. Angiogenesis undergoes multiple discrete steps that ...

Reducing GABA(A)-mediated inhibition improves forelimb motor function after focal cortical stroke in mice

Silvestro Micera

A deeper understanding of post-stroke plasticity is critical to devise more effective pharmacological and rehabilitative treatments. The GABAergic system is one of the key modulators of neuronal plasticity, and plays an important role in the control of "cr ...

The effects of stress during early postnatal periods on behavior and hippocampal neuroplasticity markers in adult male mice

Maria del Carmen Sandi Perez, Jocelin Grosse, Olivia Zanoletti, Aurélie Lattion

Infancy is a critical period for brain development. Emerging evidence indicates that stress experienced during that period can have long-term programming effects on the brain and behavior. However, whether different time periods represent different vulnera ...

Social deficits induced by peripubertal stress in rats are reversed by resveratrol

Maria del Carmen Sandi Perez, Olivia Zanoletti, Guillaume Poirier

Adolescence is increasingly recognized as a critical period for the development of the social system, through the maturation of social competences and of their underlying neural circuitries. The present study sought to test the utility of resveratrol, a di ...

The Consequences of adolescent chronic unpredictable stress exposure on brain and behavior

Fiona Hollis

There is increasing evidence for adolescence as a time period vulnerable to environmental perturbations such as stress. What is unclear is the persistent nature of the effects of stress and how specific these effects are to the type of stressor. In this re ...

Hyperconnectivity and Slow Synapses during Early Development of Medial Prefrontal Cortex in a Mouse Model for Mental Retardation and Autism

Michele Giugliano

Neuronal theories of neurodevelopmental disorders (NDDs) of autism and mental retardation propose that abnormal connectivity underlies deficits in attentional processing. We tested this theory by studying unitary synaptic connections between layer 5 pyrami ...

The timing of exploratory decision-making revealed by single-trial topographic EEG analyses

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Micah Murray, Nicolas Bourdaud

Decision-making in an uncertain environment is driven by two major needs: exploring the environment to gather information or exploiting acquired knowledge to maximize reward. The neural processes underlying exploratory decision-making have been mainly stud ...

The important role of pressure in supercritical fluid process development revealed by reaction calorimetry

Thierry Meyer

The technique of reaction calorimetry adapted for use with reactions in supercritical fluids was used to study some safety aspects of the free-radical dispersion polymerization of methyl methacrylate in scCO2. The reaction heat rate profile was found to ch ...
