Front Neurol . 2023 Mar; 14:1071766. PMID: 36970519
Introduction: The cocktail-party problem refers to the difficulty listeners face when trying to attend to relevant sounds that are mixed with irrelevant ones. Previous studies have shown that solving these...

iScience . 2022 Sep; 25(9):104997. PMID: 36111257
Communicating in everyday situations requires solving the cocktail-party problem, or segregating the acoustic mixture into its constituent sounds and attending to those of most interest. Humans show dramatic variation in...

Mathias S, Knowles E, Mollon J, Rodrigue A, Koenis M, Alexander-Bloch A, et al.
Cereb Cortex . 2020 Feb; 30(6):3439-3450. PMID: 32037459
Previous studies suggest that gyrification is associated with superior cognitive abilities in humans, but the strength of this relationship remains unclear. Here, in two samples of related individuals (total N ...

Diabetologia . 2020 Feb; 63(5):977-986. PMID: 32016567
Aims/hypothesis: Type 2 diabetes is associated with cognitive impairments, but it is unclear whether common genetic factors influence both type 2 diabetes risk and cognition. Methods: Using data from 1892...

Brain Behav Immun . 2019 Apr; 80:292-299. PMID: 30953777
Background: Suicide is major public health concern. It is imperative to find robust biomarkers so that at-risk individuals can be identified in a timely and reliable manner. Previous work suggests...

Alexander-Bloch A, Mathias S, Fox P, Olvera R, Goring H, Duggirala R, et al.
Cereb Cortex . 2017 Dec; 29(1):106-118. PMID: 29190330
The cerebral cortex may be organized into anatomical genetic modules, communities of brain regions with shared genetic influences via pleiotropy. Such modules could represent novel phenotypes amenable to large-scale gene...

J Neurosci . 2017 Apr; 37(18):4735-4743. PMID: 28385874
The accurate estimation of age using methylation data has proved a useful and heritable biomarker, with acceleration in epigenetic age predicting a number of age-related phenotypes. Measures of white matter...
