A research project of which imaging studies carried out in UMRAM has been published in Neuroscience Letters. The research entitled ‘Perisylvian GABA levels in schizophrenia and bipolar disorder' by Dr. Murat İlhan Atagün and his group has aimed  to measure GABA levels of perisylvian cortices in schizophrenia and bipolar disorder patients, using proton magnetic resonance spectroscopy (1H-MRS). In this study patients with schizophrenia (n = 25), bipolar I disorder (BD-I; n = 28) and bipolar II disorder (BD-II; n = 20) were compared with healthy controls (n = 30). 1H-MRS data was acquired using a Siemens 3 T whole body scanner to quantify right and left perisylvian structures’(including superior temporal lobes) GABAlevels. Right perisylvian GABAvalues differed significantly between groups [2 = 9.62, df: 3, p = 0.022]. It is concluded that GABA levels were significantly higher in the schizophrenia group compared with the healthy control group (p = 0.002). Furthermore, Chlorpromazine equivalent doses of antipsychotics correlated with right hemisphere GABA levels (r2 = 0.68, p = 0.006, n = 33). GABA levels are elevated in the right hemisphere in patients with schizophrenia in comparison to bipolar disorder and healthy controls. The more on this article can be found here
