Altered potassium levels in neurons may cause mood swings in bipolar disorder
Increased potassium currents were responsible for hyperactivity of CA3 neurons. When exposed to potassium channel blockers, the hyperactivity disappeared. However, when exposed to lithium, the drug not only reversed hyperactivity but reduced potassium currents at the same time. The findings strengthen the case that potassium currents play a role in bipolar disorder.... Read More...

Molecular link between chronic pain and depression revealed
Inhibitory inputs to the neural circuit between the dorsolateral bed nucleus of the stria terminalis (dlBNST) to the ventral tegmental area (VTA) increase when a person is in chronic pain. This alteration is mediated by enhanced corticotropin-releasing factor signaling within the dlBNST, leading to suppression of the mesolimbic dopaminergic system. The result is depressive mood and anhedonia associated with chronic pain.... Read More...
