Deconstructing Temporal Stages of Prosocial and Antisocial Risky Decision-making in Adolescence.
J Cogn Neurosci
January 2025
Shahid Beheshti University, Tehran, Iran.
Risk-taking is a prominent aspect of adolescent behavior. A recent neurodevelopmental model suggests that this trait could influence prosocial and antisocial decision-making, proposing a new category known as prosocial and antisocial risk-taking. The primary objective of this study was to examine the electrophysiological underpinnings of prosocial and antisocial risk-taking in adolescence, a developmental period characterized by elevated risky, prosocial, and antisocial decisions.

Recent studies suggest that calcitonin gene-related peptide (CGRP) neurons in the parabrachial nucleus (PBN) represent aversive information and signal a general alarm to the forebrain. If CGRP neurons serve as a true general alarm, their activation would modulate both passive nad active defensive behaviors depending on the magnitude and context of the threat. However, most prior research has focused on the role of CGRP neurons in passive freezing responses, with limited exploration of their involvement in active defensive behaviors.

Department of Experimental Psychology, Ghent University, Ghent, Belgium.
Pupil size is a well-established marker of cognitive effort, with greater efforts leading to larger pupils. This is particularly true for pupil size during task performance, whereas findings on anticipatory effort triggered by a cue stimulus are less consistent. For example, a recent report by Frömer et al.

Recent advancements in tissue engineering have promoted the development of nerve guidance conduits (NGCs) that significantly enhance peripheral nerve injury treatment, improving outcomes and recovery rates. However, utilising tailored biomimetic three-dimensional (3D) topological porous structures combined with multiple bio-effect neurotrophic factors to create environments similar to neural tissues, regulate local immune responses, and develop a supportive microenvironment to promote peripheral nerve regeneration and repair poses significant challenges. Herein, a biomimetic extracellular matrix (ECM) NGC featuring an interconnected 3D porous network and sustained delivery of insulin-like growth factor-1 (IGF-1) is designed using multi-functional gelatine microcapsules (GMs).

Cardiovascular diseases account for ~40% of global deaths annually. This situation has revealed the urgent need for the investigation and development of corresponding drugs for pathogenesis due to the complexity of research methods and detection techniques. An in vitro cardiomyocyte model is commonly used for cardiac drug screening and disease modeling since it can respond to microphysiological environmental variations through mechanoelectric feedback.
