Neurophysiological response to social feedback in stressful situations

European Journal of Neuroscience, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 18, 2024

Abstract The relationship between external feedback and cognitive neurophysiological performance has been extensively investigated in social neuroscience. However, few studies have considered the role of positive negative on electroencephalographic (EEG) moderate stress response. Twenty‐six healthy adults underwent a moderately stressful job interview consisting modified version Trier Social Stress Test. After each preparation, was provided by an committee, ranging from to with increasing impact subjects. response measured analysing times (RTs) during speech phase, while assessed using Stroop‐like task before after test. Results indicate that RTs used deliver final speeches were significantly lower compared those for initial feedback. Moreover, generalized improvement observed post‐SST pre‐SST. Consistent behavioural results, EEG data indicated greater delta, theta, alpha band responses right prefrontal left central areas, delta theta bands, also parietal areas aversive‐neutral feedback, highlighting effort required former. Conversely, increase these bands temporal occipital following aversive indicative adaptive emotion‐regulatory processes. These findings suggest noncritical conditions could contribute improving individual performance.

Effects and neural correlates of tDCS on anhedonia in MDD: A randomized clinical trial

Psychiatry Research, Journal Year: 2025, Volume and Issue: 350, P. 116525 - 116525

Published: April 27, 2025

Transcranial direct current stimulation (tDCS) targeting the left dorsolateral prefrontal cortex (DLPFC) has been explored as a potential add-on therapy for anhedonia in major depressive disorder (MDD), condition often resistant to conventional antidepressants. This study aimed further evaluate effects and neural correlates of adjunctive tDCS on MDD. randomized, double-blind, sham-controlled recruited 70 MDD patients, whom 56 completed protocol. Assessments were conducted at baseline after two weeks intervention, utilizing clinical evaluations depression anhedonia, alongside task- resting-state EEG measurements. Our results demonstrated that significantly improved overall symptoms anhedonia. Notably, we observed more pronounced negative-going shift Feedback-Related Negativity amplitude during Guessing-Door Task enhanced occipital alpha power spectral density EEG. Moreover, increases activity inversely correlated with subjective severity, measured by Snaith-Hamilton Pleasure Scale. These findings suggest applied DLPFC can effectively reduce potentially through specific alterations brain activity.

Oscillatory brain dynamics underlying affective face processing

Social Cognitive and Affective Neuroscience, Journal Year: 2025, Volume and Issue: 20(1)

Published: Jan. 1, 2025

Abstract Facial expressions are ubiquitous and highly reliable social cues. Decades of research has shown that affective faces undergo facilitated processing across a distributed brain network. However, few studies have examined the multispectral dynamics underlying face processing, which is surprising given multiple regions rapid temporal thought to be involved. Herein, we used magnetoencephalography derive dynamic functional maps angry, neutral, happy in healthy adults. We found stronger theta oscillations shortly after onset relative neutral (0–250 ms), within ventral visual parietal cortices, anterior hippocampus. Early gamma (100–275 ms) were strongest for angry inferior lobule, temporoparietal junction, presupplementary motor cortex. Finally, beta (175–575 middle occipital fusiform These results consistent with literature regard critical regions, delineate network where oscillatory support through merging low-level inputs interpret emotional meaning each facial expression.

Study on the effects of traffic noise and spring water sound at different sound pressure levels on brain dynamic activity

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: May 14, 2025

The correlation between sound and psychophysiological health is complex. This study explores effects of various pressure levels (SPLs) on responses, utilizing dynamic features neural activity. Two types (traffic noise spring water sound) five SPLs (40, 45, 50, 55, 60 dBA) were tested, with no serving as the control condition. electrocardiography (ECG) electroencephalogram (EEG) 38 young college students collected. results indicate that (SWS) significantly enhances perception, comfort votes (SCV) pleasure (SPV) increasing by 0.10-0.95 0.05-1.10, respectively. SWS facilitated parasympathetic nervous system comfort. Compared to sound, increased, LF/HF decreased (by 0.07-0.41), SDNN increased 8.85-18.56 ms), whereas traffic (TN) exhibited opposite trend. For brain oscillatory activity, α, θ, β power-associated stress recovery-initially then rising under exposure. At 50 dBA SWS, effective delay duration, linked comfort, peaked at 284.78 ms. Conversely, α power τe for TN diminished SPLs. left frontal-parietal right occipital lobes highest sensitivity (p < 0.01). exposure reduced avalanche critical index (ACI) 4.78-17.29% compared enhancing while ACI 2.28-29.37%. showed greatest improvement in being 1.74 times higher than TN. Furthermore, loss was lower 52.63-63.16% participants exposed 50-60 SWS. provides a methodology soundscape evaluation understanding how activity changes can improve indoor acoustic environment.
