Resting-state fMRI activation is associated with phenotypic features of autism in early adolescence
In this study, we aimed to explore if activation in brain regions of the default mode network (DMN), specifically the medial prefrontal cortex (MPC), posterior cingulate cortex (PCC), superior temporal sulcus (STS), inferior frontal gyrus (IFG), angular gyrus (AG), and the temporoparietal junction (TPJ), during resting-state functional magnetic resonance imaging (rs-fMRI) is associated with possible…

Menstruation Problems and Sleep Interactions: Implications for the Mental Health of Adolescent Females
Internalizing symptoms are associated with menstrual cycle characteristics and menstrual pain in female adolescents, especially in those with shorter sleep and later bedtimes. The relationship between the menstrual cycle, sleep, and psychophysiology needs to be integrated in healthcare practice to promote well-being and resilience in young female adolescents.

A Longitudinal Study of the Relationship Between Alcohol-Related Blackouts and Attenuated Structural Brain Development
Alcohol-related blackouts (ARBs) are common in adolescents and emerging adults. ARBs may also be indicative of persistent, alcohol-related neurocognitive changes. This study explored ARBs as a predictor of altered structural brain development and associated cognitive correlates

Neurofunctional characteristics of executive control in older people with HIV infection: a comparison with Parkinson’s disease
Expression of executive dysfunctions is marked by substantial heterogeneity in people living with HIV infection (PLWH) and attributed to neuropathological degradation of frontostriatal circuitry with age and disease.

Physiological Responses to Acute Psychosocial Stress in Women with Menopausal Insomnia
Insomnia disorder is a common sleep disorder and frequently emerges in the context of menopause, being associated with menopause-specific factors such as hot flashes and other psychosocial variables.

Compromised Frontocerebellar Circuitry Contributes to Nonplanning Impulsivity in Recovering Alcoholics
We tested the hypothesis that alcoholic patients would demonstrate compromised dorsal anterior cingulate cortex (dACC) -cerebellar functional connectivity when adjusting their strategies to accommodate uncertain conditions and would recruit compensatory brain regions to overcome ineffective response patterns.

Interhemispheric Functional Connectivity Change Is Linked to Callosal Fiber Integrity Change over a 1-Year Follow-up in Chronic Alcoholics
We tested whether microstructural fiber changes relate to resting-state functional connectivity changes in alcoholics who have maintained sobriety during a one-year interval, and whether these changes are beyond those potentially exhibited by controls.

Synchrony of Anterior Cingulate Cortex and Insular-Striatal Activation Predicts Ambiguity Aversion in Individuals with Low Impulsivity
To test how dACC functional network connectivity would be modulated by uncertainty and differ between individuals, 24 healthy participants underwent functional MRI in 3 sequential runs: 1 resting-state and 2 decision-making task runs. Individuals with lower nonplanning impulsiveness made greater use of a Pass option and avoided uncertain ambiguous situations.

Diffustion Tensor Imaging Detects Callosal Fiber Integrity Change over a 1-Year Follow-up in Chronic Alcoholics Who Maintained Sobriety
Here, we investigated change in CC microstructural fiber integrity over one year in 12 (7w, 5m) alcoholics (ALC) and 13 (7w, 6m) age-matched controls (CTL). ALC and CTL did not differ in years of education (mean=15 years for both groups) or verbal IQ (CTL=107, ALC=104).

Fiber Tract-Driven Topographical Mapping (FTTM) Reveals Microstructural Relevance for Interhemispheric Visuomotor Function in the Aging Brain
We present a novel approach – DTI-based fiber tract-driven topographical mapping – to map and measure the influence of age on the integrity of interhemispheric fibers and challenge their selective functions with measures of interhemispheric integration of lateralized information.
