... One focus has been on change in self-esteem trajectories across adolescence at both the group mean and individual level, (57,58) with pronounced decreases specifically seen in girls. (59) Studies have also documented increases across development in self-consciousness,(60,61) self-complexity, (62,63) and self-disclosure. (64) Other research has suggested that mentalizing (cognitive perspective-taking) also continues to improve, as seen by increased accuracy and decreased reaction time on laboratory mentalizing tasks.(65-67) ...

... Our findings indicate a significant downregulation in the expression of PSD95 and SYN in the hippocampus of mice with diet-induced insulin resistance. Extensive literature supports the beneficial effects of exercise on insulin resistance [32][33][34], hippocampal neuronal synaptic plasticity [35], and cognitive impairments [36][37][38]. Although there is substantial evidence for the positive effects of aerobic exercise on cognitive functions [39][40][41], research on the impacts of resistance training on cognitive functions is less prevalent. ...
