Objective: The pathophysiology of depression and the effects of antidepressant treatment are hypothesized to be related to hippocampal structural changes. This study aims to investigate the effect of electroconvulsive seizures on behavior and hippocampal structure in a rat model of depression. Methods: Flinders Sensitive Line (FSL) and Flinders Resistant Line (FRL) rats were treated daily for 10 days...
The aim was to investigate treatment effects of the antidepressant imipramine on the markers of neuronal plasticity. We investigated changes in neuron and synapse numbers in a rat strain that displays a genetic susceptibility to depressive behavior, the Flinders Sensitive and Resistant Lines (FSL/FRL). All rats were treated with imipramine (15 mg/kg) or saline (i.p) once daily for 25 days. The volume,...
The underlying mechanism of the therapeutic effect of electroconvulsive therapy (ECT) is still unclear. Here we investigated whether repeated electroconvulsive seizures (ECS), an animal model of ECT, in rats induce neuroplastic changes in the subregions of the hippocampus. ECS or sham treatment was given daily for 10 days to adult male rats. Stereological principles were employed to quantify volumes...
