Checking Behavior

Obsessive-compulsive disorder (OCD) affects ∼1 to 3% of the world’s population. However, the neural mechanisms underlying the excessive checking symptoms in OCD are not fully understood. Using viral neuronal tracing in mice, we found that glutamatergic neurons from the basolateral amygdala (BLAGlu) project onto both medial prefrontal cortex glutamate (mPFCGlu) and GABA (mPFCGABA) neurons that locally innervate mPFCGlu neurons. Next, we developed an OCD checking mouse model with quinpirole-induced repetitive checking behaviors. This model demonstrated decreased glutamatergic mPFC microcircuit activity regulated by enhanced BLAGlu inputs. Optical or chemogenetic manipulations of this maladaptive circuitry restored the behavioral response. These findings were verified in a mouse functional magnetic resonance imaging (fMRI) study, in which the BLA–mPFC functional connectivity was increased in OCD mice. Together, these findings define a unique BLAGlu→mPFCGABA→Glu circuit that controls the checking symptoms of OCD.

AbstractRecently, we found that morphine promoted presynaptic glutamate release of dopamine (DA) neurons in the ventral tegmental area (VTA), which constituted the main mechanism for morphine-induced increase in VTA-DA neuron firing and related behaviors (Chen et al., 2015). However, what source of presynaptic glutamate release of DA neurons in the VTA is promoted by morphine remains unknown. To address this question, we used optogenetic strategy to selectively activate glutamatergic inputs from different projection neurons and then observed the effect of morphine on them. The result shows that morphine promotes glutamate release from glutamatergic terminals of projection neurons from the medial prefrontal cortex (mPFC) to VTA DA neurons, but has no effect on that from the basolateral amygdala (BLA) or the lateral hypothalamus (LH) to VTA DA neurons, and the inhibition of glutamatergic projection neurons from the mPFC to the VTA significantly reduces morphine-induced increase in locomotor activity of mice.
