Dietary fats entering the brain may explain link between obesity and depression: Mouse study

A mechanism that links exposure to high-fat diets in mice to changes in hypothalamic function which leads to depression has been identified. Saturated fatty acids enter the brain via the bloodstream, where they accumulate and affect key signaling pathways associated with the development of depression.

General anesthesia hijacks sleep circuitry to knock you out

Study reveals anesthesia activated neurons have been discovered in the hypothalamus. Activation of AANs promotes slow-wave sleep, extending the effects of anesthesia, while inhibition of AANs shortens the duration of general anesthetics and disrupts natural sleep.

Had Enough Water? Brain’s Thirst Centers Make a Gut Check

Hydration signals from the gut travel via the vagus nerve to activate thirst neurons in the SFO. These neurons signal to cells in the median preoptic nucleus, driving animals to drink and the kidneys to conserve water in the bloodstream.

Finding the Elusive Drinking ‘Brake’

Researchers have uncovered a mechanism in the BNST that senses the negative effects of alcohol and modulates the urge to drink. The study reports that when this mechanism doesn't function correctly, we lose the ability to recognize that we have had enough to drink.

Rewriting the Brain Pathway for Consciousness

Researchers say a new discovery about the pathways associated with consciousness contradicts conventional belief. The study reports the thalamus is not a critical part of the brain's pathway involved in wakefulness and consciousness, a finding that could help develop better methods for treating comas.
