Structural and functional alterations in hypothalamic subregions in male patients with alcohol use disorder.
Drug Alcohol Depend
January 2025
Department of Neurology, Incheon St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea.
Background: The hypothalamus is involved in stress regulation and reward processing, with its various nuclei exhibiting unique functions and connections. However, human neuroimaging studies on the hypothalamic subregions are limited in drug addiction. This study examined the volumes and functional connectivity of hypothalamic subregions in individuals with alcohol use disorder (AUD).

Electronic address:
Background: A few studies linked air pollution to differences in functional connectivity of resting-state brain networks in children, but how air pollution exposure affects the development of brain networks remains poorly understood. Therefore, we studied the association of air pollution exposure from birth to 3 years and one year before the first imaging assessment with the development of functional connectivity across adolescence.
Methods: We utilized data from 3,626 children of the Generation R Study (The Netherlands).
Iodine intakes of pregnant females from Québec, Canada.
J Trace Elem Med Biol
January 2025
Reproduction, Mother and Child Health Unit, Research Center of the CHU de Québec, Université Laval, Québec City, Québec, Canada; Department of Obstetrics, Gynecology and Reproduction, CHU de Québec-Université Laval, Québec City, Québec, Canada. Electronic address:
Background: Adequate maternal iodine intake is important for fetal brain development. Based on iodine intakes of non-pregnant females of reproductive age from the Canadian Health Measures Survey (2016 -2017) it can be extrapolated that most pregnant females in Canada will not meet iodine requirements without supplementation.
Objectives: To assess iodine intakes of 500 pregnant, nulliparous females from Québec, Canada and report on use of multivitamin/mineral (MVM) supplements and coverage of iodized salt.
Which type of feedback-Positive or negative- reinforces decision recall? An EEG study.
Front Syst Neurosci
January 2025
International research center for Cognitive Applied Neuroscience (IrcCAN), Università Cattolica del Sacro Cuore, Milan, Italy.
This study examines the impact of positive and negative feedback on recall of past decisions, focusing on behavioral performance and electrophysiological (EEG) responses. Participants completed a decision-making task involving 10 real-life scenarios, each followed by immediate positive or negative feedback. In a recall phase, participants' accuracy (ACC), errors (ERRs), and response times (RTs) were recorded alongside EEG data to analyze brain activity patterns related to recall.

Brain Commun
January 2025
Department of Clinical Medicine, Aarhus University Hospital, Aarhus N, 8200 Aarhus, Denmark.
Asymmetric dopaminergic degeneration of the striatum is a characteristic feature of Parkinson's disease, associated with right-left asymmetry in motor function. As such, studying asymmetry provides insights into progressive neurodegeneration between cerebral hemispheres. Given the impact of Lewy pathology on various neurotransmitter systems beyond the dopaminergic, it may be that other neuronal systems in the predominantly affected hemisphere are similarly affected.
