Though stronger neural entrainment (i.e., brain-to-acoustic synchronization) aids speech perception, underlying oscillatory activity may uniquely interact with long-term auditory experiences (i.e., music training) and short-term plasticity during concurrent speech perception. Here, we explored oscillatory activity during rapid auditory perceptual learning of concurrent speech sounds in normal-hearing young adults who differed in their amount of self-reported music training (defined as “musicians” and “nonmusicians”). Participants learned to identify double-vowel mixtures during ~45 min training sessions with concurrent high-density EEG recordings. We analyzed alpha-band power (7–12 Hz) following a rhythmic speech-stimulus train (~9 Hz) preceding behavioral identification to determine whether increased (brain-to-speech entrainment) or decreased alpha activity (alpha-band suppression) corresponded with task success. Source and directed functional connectivity analyses of EEG data probed whether behavior was driven by group differences in auditory-motor coupling. Both groups improved in behavioral identification with training. Listeners' alpha-band power prior to target speech predicted behavioral identification performance; surprisingly, stronger alpha oscillations were observed preceding incorrect compared to correct trial responses. We also found stark hemispheric biases in auditory-motor coupling, with greater auditory-motor connectivity in right compared to left hemisphere for musicians (R > L) but not in nonmusicians (R = L). Stronger alpha activity preceding incorrect behavioral responses supports the notion that alpha-band (~10 Hz) suppression is an important modulator of trial-by-trial success in perceptual processing. Our findings suggest that neural oscillations and auditory-motor connectivity interact with music training to impact speech perception.</p>\u0000 </div>","PeriodicalId":11993,"journal":{"name":"European Journal of Neuroscience","volume":"61 9","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143884012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this perspective review, we apply these concepts to neuroaesthetics and beauty perception, discussing how the internalization of invariants may influence our perception of beauty. Within this framework, special emphasis was placed on symmetry and golden ratio, typically considered as two benchmarks for beauty, and two geometrical features that can be considered as environmental affordances.

Stimulation of post-stroke angiogenesis using vascular endothelial growth factor (VEGF)-A is associated with an increased risk of vascular destabilization, leading to life-threatening complications. The non-mammalian VEGF-A homolog, VEGF-E, stimulates stable cutaneous vascularization and promotes wound healing. Herein, we posit that VEGF-E represents a potential mediator of reparative revascularization after ischemic stroke. C57BL6/J wildtype mice were subjected to experimental stroke, and VEGF-E or VEGF-A were intranasally delivered during the subacute phase. Our results indicate that VEGF-E improves neurological recovery and increases vascular density without compromising permeability, more efficiently than VEGF-A. We show that VEGF-E-mediated revascularization correlates with normal restoration of brain perfusion, whereas VEGF-A induces cerebral hyperperfusion, indicative of vascular dysfunction. Furthermore, VEGF-E reduces microvascular stalls, increases the density of angiogenic vasculature, and improves the interaction of brain endothelial cell with pericytes, which is critical for vascular stabilization. Using cell-based assays, we demonstrate that stimulation of brain endothelial cells with VEGF-E, but not with VEGF-A, increases the expression of platelet-derived growth factor (PDGF)-D, a potent ligand of PDGFRβ that plays critical roles in regulating the survival and functions of perivascular cells, including pericytes. These effects are associated with activation of extracellular signal-regulated kinase (ERK)1/2 and P38 mitogen-activated protein kinase (MAPK). Finally, we confirm that the secretome of VEGF-E-stimulated brain endothelial cells ameliorates pericyte migration required for vascular recruitment.

To counteract the costs, reduced accessibility, and complexity of brain imaging (e.g., CT scans and fMRI) or function tests, neurocognitive performance tests (e.g., the Stroop test, the Trail Making Test, or the Choice Reaction Task) are commonly implemented. Although reliability is considered paramount when interpreting intervention effects, a detailed quantification of systematic and random errors is scarce. By recruiting 68 healthy participants from different age groups (7–64 years), we quantified population-specific measurement errors in the aforementioned neurocognitive tasks. The goal was to raise awareness about the impact of learning effects on reliability assessments and their interpretation. By performing five testing sessions with two trials per day, we observed significant learning effects from repeated testing. Trial-to-trial improvements of up to 50% were measured, accompanied by a random measurement error reduction from day to day. These learning effects were task and population specific, highlighting the need for caution when transferring reliability coefficients from other studies. The quantification of systematic and random measurement errors underscores the importance of conducting sufficient habituation sessions in neurocognitive tasks, as test protocols lack validity if they do not ensure reliability.
