Episodic memory shows striking improvement during early childhood. However, neural contributions to these behavioral changes are not well understood. This study examined associations between episodic and volume of subregions (head, body, tail) the hippocampus-a structure known support in school-aged children adults-during childhood (n = 45). Results revealed significant positive relations hippocampal head both left right hemispheres for 6- but 4-year-old children, suggesting brain-behavior...
Abstract Introduction Heterogeneity of segmentation protocols for medial temporal lobe regions and hippocampal subfields on in vivo magnetic resonance imaging hinders the ability to integrate findings across studies. We aim develop a harmonized protocol based expert consensus histological evidence. Methods Our international working group, funded by EU Joint Programme–Neurodegenerative Disease Research (JPND), is toward production reliable, validated, regions. The group uses novel postmortem...
Adolescence is frequently described as a developmental period characterized by increased sensitivity to rewards. However, previous research on age-related changes in the neural response gains and losses have produced mixed results, with only some studies reporting potentiated responses during adolescence. The current study examined ERP simple monetary reward (i.e., Doors) task large longitudinal sample of 248 adolescent females assessed at two time points, separated years. At baseline, when...
Understanding how event-related potentials (ERPs) change following repeated assessments is critical to advance our understanding of neural mechanisms implicated in psychopathology. Specifically, it unclear if associations between ERPs and individual differences can be reproduced when repeatedly measured within the same participants, or clinical characteristics impact ERP trajectories over assessments. The present study assessed P300 amplitude latency from a flanker task at four time points...
Abstract The menstrual cycle impacts mood and neural response to reward—phenomena that may be related natural fluctuations in ovarian hormones. Using a within‐subject design, the present study examined hormones (i.e., estradiol progesterone) ERPs feedback indicating gains losses both follicular luteal phases of cycle. We whether hormone levels variation reward loss across were associated with depressive symptoms. Participants high symptoms showed reduced positivity (RewP) monetary during...
Background and Objectives Suicidal ideation (SI) during the postpartum phase is linked with suicide, a leading cause of death this period. Antenatal depression anxiety symptoms have both been increased risk for SI. However, research aimed at examining relative contributions antenatal towards SI remains nascent. In study, we investigated contribution symptoms,
Abstract The late positive potential (LPP) is characterized by temporal and spatial changes across development—though existing work has primarily relied on visual or statistical comparisons of relatively few electrodes averaged activity over time. current study used an empirically based approach to characterize in ERPs Data were utilized from a large longitudinal ( N = 380) which the LPP was recorded pleasant, neutral, unpleasant pictures around age 9 again 12. Age subtracted 12 for all...
A recent study by Tsypes and colleagues (2019) found that children with suicidal ideation had blunted neural reward processing, as measured the positivity (RewP), compared to matched controls, this difference was driven reduced responses monetary loss, rather than reward. Here, we aimed conceptually replicate extend these findings in two samples (n = 264, 27 ideation; n 314, 49 at baseline) of adolescents (11 15 years 8 years, respectively). Results from both showed no evidence have abnormal...
Background: Across several patient cohorts recruited for recent suicidal ideation (SI), current affective disorder, and natural menstrual cycles, we have observed a dimensional (present to varying degrees) perimenstrual (PM) worsening of SI depressed mood, specifically relative an early luteal (EL) nadir. In our prior crossover trial, PM administration combined estradiol (E2) progesterone (P4) reduced this exacerbation depressive symptoms versus placebo (PBO). This three-period trial...
The P300 event-related potential (ERP) has been extensively studied across the human lifespan. However, many studies examining age-related effects are cross-sectional, and few have considered unique role that pubertal development may on developmental trajectories. current study examined whether age, maturation or their interaction predicted changes in amplitude over two years among 129 females between ages of 8 15 at baseline. Participants completed a flanker task while EEG was recorded...
Event-related potentials (ERPs) are widely employed as measures of transdiagnostic cognitive processes that thought to underlie various clinical disorders (Hajcak et al., 2019). Despite their prevalent use individual difference measures, the effects within-person processes, such human menstrual cycle, on a broad range ERPs poorly understood. The present study leveraged within-subject design characterize between- and variance in well contribution cycle two frequently studied associated with...
