g-aminobutyric acid type A receptors that incorporate a5 subunits (a5-GABAARs) are highly enriched in the hippocampus and they are strongly implicated in the control of learning and memory.

Speakers were presented with different auditory perturbations to both vowels in the word “bedhead” (left panel); one vowel was altered toward the vowel /æ/ (“had”) and the other toward /ɪ/ (“hid”), with the order balanced across participants.

Alzheimer’s disease is characterized by accumulation of amyloid and neurofibrillary tangles, and this pathology can be detected using neuroimaging or fluid biomarkers prior to the development of dementia. The Alzheimer’s disease process also involves neurodegeneration which eventually leads to cognitive decline and dementia, however typical approaches for measuring neurodegeneration (such as T1-weighted imaging), may not be sensitive to neurodegeneration in the asymptomatic disease stage.

There is substantial heterogeneity in the development of depression from adolescence into adulthood. Yet, little is known about the risk factors underlying its various patterns of development. For instance, despite the discovery of genetic variants for depression, these discoveries have not accounted for the high degree of genetic covariation between multiple disorders, nor have they been applied to disambiguate its heterogeneous developmental presentations.

Adults with Down syndrome (DS) are predisposed to Alzheimer’s disease (AD) and a characterization of glucose metabolism change throughout AD progression has yet to be performed in this population. Using FDG PET, regional glucose metabolism was evaluated across groups of cognitively stable DS (CS-DS), DS with mild cognitive impairment or Alzheimer’s disease (MCI-DS/AD), and healthy non-DS sibling controls.

Demonstration of the ability of MPnRAGE to correct for severe motion artifacts in a 7 year old girl. Retrospective motion correction greatly reduced motion-induced blurring in both structural T1-weighted images and quantitative T1 maps. The correction greatly improves the reliability of brain imaging measurements in children. The plots indicate the estimated amount of head motions that were corrected.

Gene expression levels vary across developmental stage, cell type, and region in the brain. Genomic variants also contribute to the variation in expression, and some neuropsychiatric disorder loci may exert their effects through this mechanism. To investigate these relationships, we present BrainVar, a unique resource of paired whole-genome and bulk tissue RNA sequencing from the dorsolateral prefrontal cortex of 176 individuals across prenatal and post- natal development.
