Article Abstract
In the study we investigated how current mood affects spontaneous perceptual processes of neutral stimuli of low‑arousal, unrelated to any specific task. Two separate but similar procedures were carried out: one using functional magnetic resonance imaging (fMRI), the other using electroencephalography based source localization. In both experiments, sessions of passive viewing of neutral pictures were preceded by either a negative or positive mood induction. In response to neutral stimuli, we observed higher activation of visual areas after positive mood induction and lower activations in medial prefrontal and right frontotemporal regions after negative mood induction. We conclude that in relatively safe laboratory conditions, after being exposed to negative emotional content, automatic processes of affective control are recruited by the prefrontal cortex. This results in attenuation of processing of incoming stimuli, as the stimuli do not carry salient information with respect to bottom‑up or top‑down processes. The observed effects may therefore represent an implicit mechanism of perceptual modulation.

Introduction: Several studies indicate that a specific genotype profile could influence ovarian sensitivity to exogenous gonadotropin. However, most of the previous studies were observational and retrospective and thereby more prone to bias. The aim of this study was to evaluate the impact of gonadotropin single nucleotide polymorphisms (SNPs) on the outcomes of fertilization (IVF) in infertile patients undergoing their first ovarian stimulation (OS) cycle.

Working memory (WM) regulates information flow through gate mechanisms, consisting of four subprocesses: gate opening, gate closing, updating, and substitution. However, their neural mechanisms remain underexplored. While emotion-cognition interactions are well studied, the effects of negative mood on these subprocesses are unclear.

Prior research suggests that cortisol responses to acute stress induction paradigms (i.e., "cortisol stress reactivity") likely arise from complex interactions between experiment-level, biological, and psychological factors.

Objective: Although emotions and postural control are strongly intertwined, more research is necessary to understand this intricate relationship. Therefore, we examined the effect of script-driven emotional imagery on postural control in healthy individuals.
Methods: Forty-four healthy participants (50 % female, median age=27) imagined three emotional imagery scripts (hostile, acceptance, relaxation) in upright standing without visual input while center of pressure (CoP) was measured (mean sway, sway velocity, , and standard deviation in antero-posterior and medio-lateral directions, and sway path and area).

General control nonderepressible 2 (GCN2; EIF2AK4) is a serine-threonine kinase in the integrated stress response signaling pathway that initiates adaptive responses during nutrient stress conditions. Although pharmacologic inhibition of GCN2 under nutrient stress conditions induces apoptosis and inhibits tumor growth, GCN2 inhibition without nutrient stress has been reported to have no effect on tumor growth. By exploring an array of GCN2 inhibitors, we demonstrate that multiple agents in fact activate GCN2 in biochemical and cell-based assays at low concentrations and inhibit GCN2 at higher concentrations.
