“…Investigators have suggested that neurotransmitter signaling may occur via clustering of receptors in lipid rafts or caveolae, and the effects of lipid rafts on neurotransmitter signaling have been implicated in neurological and psychiatric diseases in general (Nomura et al , 2008, Pani and Singh, 2009), and in mood disorders in particular (Brambilla et al , 2003, Shiah and Yatham, 2000, Donati et al , 2008). Traditionally, the brain systems receiving the greatest attention in neurobiological studies of mood disorders were the monoaminergic neurotransmitter systems (e.g., the serotonergic, dopaminergic, and norepinephrinergic systems) that are extensively distributed throughout the network of limbic, striatal, hippocampal, and prefrontal cortical neuronal circuits (Drevets, 2000, Manji and Duman, 2001, Nestler et al , 2002).…”
