Finding the root of consciousness: Is this brain cell your ‘mind’s eye’?

Researchers believe they have identified specific neurons that are responsible for conscious awareness. Previous studies have implicated both thalamocortical circuits and cortico-cortico circuits in consciousness. The new study reports these networks intersect via L5p neurons. Directly activating L5p neurons made mice react to weaker sensory stimuli. The researchers say if consciousness requires L5p neurons, all brain activity without them must be unconscious....

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...

Stressed out: Americans making themselves sick over politics

Exposure to political news may be having a detrimental effect on the public health of the American people, researchers say. A new study reveals 40% of Americans surveyed say politics increases their stress levels, with 1 in 5 people actively losing sleep as a result of political exposure. 20% of those surveyed say politics has damaged interpersonal relationships, and 4% of the sample reported suicidal thoughts because of the current political climate....
