The GABRB1 gene is associated with thalamus volume and modulates the association between thalamus volume and intelligence.

article i nfo Article history: Accepted 25 August 2014 Available online 2 September 2014 The GABRB1 gene encodes the beta 1 subunit of the gamma-aminobutyric acid A receptor (GABA A receptor), which is responsible for mediating inhibitory neurotransmission in the thalamus. Potential relationships be- tween the GABRB1 gene, thalamus volume, and intelligence have been suggested by previous clinical studies, but have not been directly examined among nonclinical samples. The current study collected structural MRI, ge-
