Title

Neuro-metabolite profiles of rodent models of psychiatric dysfunctions characterised by MR spectroscopy

Overall design

To test metabolic alterations within the glutamate-cycle and in other major neurochemicals, single-voxel Magnetic Resonance Spectroscopy was recorded within the hippocampus in both rat models and control animals. Rats were divided into the following 2 groups (n = 12 in each group): (1) control group, and (2) CUMS group. The CUMS stress procedure lasted for 4 weeks. Metabolite quantification was reported relative to total creatine as the reference peak.
