Animal models are commonly used to investigate developmental processes and disease risk, but humans and model systems (e.g., mice) differ substantially in the pace of development and aging.

The "oblique effect" refers to the reduced visual performance for stimuli presented at oblique orientations compared to those at cardinal orientations. In the cortex, neurons that respond to specific orientations are organized into orientation columns. This raises the question: Are the orientation signals in the iso-orientation columns associated with cardinal orientations the same as those in the iso-orientation columns associated with oblique orientations, and is this signal influenced by experience? To explore this, iso-orientation columns in visual area 18 were examined using optical imaging techniques.

Objective: Fetal cerebellar abnormalities are associated with neurodevelopmental disorders and structural brain malformations. Accurate and early diagnosis is crucial for prenatal counseling and planning postnatal interventions. While prenatal ultrasound is a key tool for detecting fetal brain abnormalities, variations in diagnostic accuracy across studies necessitate a systematic evaluation of its effectiveness in diagnosing cerebellar abnormalities.

Silver-Russell Syndrome (SRS) is a genetic disorder characterized by intrauterine and postnatal growth restriction. Most cases are caused by an imprinting error either with hypomethylation of the Imprinted Control Region 1 at 11p15.5, or maternal uniparental disomy of chromosome 7.

Background: Maternal stress during pregnancy may impact offspring development via changes in the intrauterine environment. However, genetic and environmental factors shared between mothers and children might skew our understanding of this pathway. This study assesses whether prenatal maternal stress has causal links to offspring outcomes: birthweight, gestational age, or emotional and behavioral difficulties, triangulating across methods that account for various measured and unmeasured confounders.
