One of the key ways that we make sense of numbers is by creating a “mental number line”. Previous research with whole numbers has demonstrated that (at least in Western cultures) small numbers are thought of as being on the left side of space, and large numbers on the right.

Using Discordant MZ Twins and Genome-wide Methylation Analyses to Identify Anxiety-relevant Genes – Three MZ (genetically identical) twin pairs were chosen to be clearly discordant for childhood cortisol levels and adolescent fMRI patterns in the amygdala that correlated with anxiety symptoms.

Generation of Human Induced Pluripotent Stem Cells from Unaffected Neonatal Skin Cells – We have generated and characterized iPSC clones from three unaffected, neonatal individuals using non-integrating episomal reprogramming plasmids expressing OCT4, SOX2, LIN28, KLF4, and c-Myc.

Cell type-specific investigations commonly employ gene reporters or single-cell (sc) analytical techniques. However, reporter line development is arduous and generally limited to a single gene of interest, while scRNA-seq frequently yields equivocal results that preclude definitive cell identification.

Immunostaining and microglia isolation via magnetic cell sorting was performed at postnatal day 2, 9, 30 and 60 (P2, P9, P30, P60). Microglia branching and soma size were quantified using semiautomated software analysis (Imaris, Oxford Insturments).

Human pluripotent stem cell-derived neural organoids provide unprecedented potential to recapitulate human brain and spinal cord tissues in vitro. However, organoid morphogenesis relies upon cell-intrinsic self-assembly of biomimetic tissue structures in the absence of normal developmental constraints and morphogen signaling centers.

Weak central coherence (processing details over gist), poor oral language abilities, poor suppression, semantic interference, and poor comprehension monitoring have all been implicated to affect reading comprehension in individuals with ASD.

Currently there are few evidence-based programs available for families of individuals with ASD during the transition to adulthood. The present study provided a preliminary evaluation of a multi-family group psychoeducation intervention using a randomized waitlist control design (n = 41).

Empathy, the ability to understand others’ emotions, can occur through perspective taking and experience sharing. Neural systems active when adults empathize include regions underlying perspective taking (e.g. medial prefrontal cortex; MPFC), and experience sharing (e.g. inferior parietal lobule; IPL).

Hormones present in hair provide summative information about endocrine activity while the hair was growing. Therefore, it can be collected from an infant after birth and still provide retrospective information about hormone exposure during prenatal development.
