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 ...

Get real: Orbitofrontal cortex mediates the ability to sense reality in early adolescents

Dimitri Nestor Alice Van De Ville, Roberto Martuzzi, Lorena Gonçalves de Alcântara e Freitas Krikler, Vanessa Siffredi

Introduction Orbitofrontal reality filtering (ORFi) is a memory mechanism that distinguishes whether a thought is relevant to present reality or not. In adults, it is mediated by the orbitofrontal cortex (OFC). This region is still not fully developed in p ...

Is the car losing its shine? An analysis of European adolescents' imaginaries of the automobile

Vincent Kaufmann, Emmanuel Pierre Jean Ravalet, Guillaume Simon Joseph Drevon

Recent scientific publications show an increase in the average age for obtaining a driving licence. This phenomenon would tend to suggest a certain disavowal of the car among young adults and teenagers. Basing on a survey of more than 8’000 teenagers in fi ...

Spatial and temporal aspects of visual backward masking in children and young adolescents

Michael Herzog

The development of visual functions is very diverse. Some visual functions mature within the first year of life, whereas maturation for other functions extends into adolescence. The reasons for these developmental differences are largely unknown. Here, we ...

Role of the HPA axis in the long-term programming of social behaviors by peripuberty stress : behavioral, pharmacological and molecular approaches

Vandana Veenit

Stress during childhood and adolescence enhances the risk of psychopathology later in life. In fact, exposure to stress during this period is known to predispose individuals to the development of psychopathologies such as depression and anxiety disorders l ...

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 ...

Increased corticosterone in peripubertal rats leads to long-lasting alterations in social exploration and aggression

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Stamatina Tzanoulinou, Vandana Veenit

Stress during childhood and adolescence enhances the risk of psychopathology later in life. We have previously shown that subjecting male rats to stress during the peripubertal period induces long-lasting effects on emotion and social behaviors. As cortico ...

Comparing the neural bases of self-referential processing in typically developing and 22q11.2 adolescents

Roy Salomon, Maude Schneider

The investigation of self-reflective processing during adolescence is relevant, as this period is characterized by deep reorganization of the self-concept. It may be the case that an atypical development of brain regions underlying self-reflective processi ...
