Reduced hippocampal volume is frequently observed in posttraumatic stress disorder (PTSD), but the psychological processes associated with these alterations remain unclear. Given hippocampal involvement in memory and contextual representations of threat, we investigated relationships between retrospectively reported combat exposure, perceived threat, and hippocampal volume in trauma-exposed veterans.

Maternal recall of distress and health concerns during pregnancy correlated with cord blood ZnPP/H indices (r = 0.21, P < .01), even in the absence of major traumatic events. When concurrent with other known risks for iron deficiency, including maternal adiposity, socioeconomic status, and race, maternal stress had a summative effect, lowering cord blood iron.
Time-to-degree improves again, setting record
Undergraduates at the University of Wisconsin–Madison are taking less time to complete their degrees, setting a record on a key measure of student success. The average time-to-degree for 2018-19 bachelor’s degree recipients was 3.96 elapsed calendar years, the lowest since the university began actively tracking the measure in the 1980s and the first time the number has dropped below four years, according to the university’s Office of Academic Planning and Institutional Research.

Individuals with Down syndrome (DS) are at increased risk of developing Alzheimer’s disease (AD) and show the earliest signs of amyloid-β (Aβ) deposition in the striatum. The metric for tracking Aβ burden using PET radiotracers frequently uses average standard uptake value ratios (SUVr) in signature regions of the brain specific to Aβ deposition.

The auditory brainstem reflex tag-team: panel A is a schematic of the neural connections between two brainstem auditory reflexes, the medial olivocochlear (MOCR) and the middle ear muscle (MEMR) reflex. While we know that the two reflexes work in tandem and at slightly different frequencies and input sound levels, how the activity of one reflex influences the other is poorly understood.
21st century medicine helps Amish deal with rare, inherited illnesses
There is no car in the driveway, neither phone nor electricity in the house. Handmade clothes dry on the line. It’s fall 2018, and La Farge physician James DeLine has brought us to talk with Barbara and Daniel Hochstetler, part of the large Amish population in Wisconsin’s Driftless Region.

To identify mechanisms that lead to neurodevelopmental differences in Down syndrome, we used induced pluripotent stem cells (iPSCs) generated from individuals with Down syndrome and differentiated them into progenitors of the cerebral cortex. The progenitors were analyzed by RNA Seq at Day 17 in culture when cells have acquired their positional phenotype.
