The brain may actively forget during dream sleep

REM sleep has previously been linked to memory formation. A new study reveals this sleep period may also be critical for us to forget certain memories, preventing information overload. Researchers identified a mechanism involving MCH neurons which causes us to forget information during sleep.

Brain activity intensity drives need for sleep

Galanin expressing neurons are selectively active during rebound sleep. The expression of galanin increases after neuronal activity and sleep deprivation. The neuropeptide plays a critical role in sleep homeostasis.

High-fat diets affect your brain, not just your physical appearance

High-fat diets are not only bad for your waistline, they are also bad for your brain health. A new study reveals high-fat diets contribute to hypothalamic inflammation which occurs long before symptoms of obesity arise.

Brain circuit connects feeding and mood in response to stress

A new study identifies a novel neural network regulating feeding and mood in response to chronic stress. Inhibiting the POMC to ventral tegmental area circuit increases body weight and food intake while reducing depressive symptoms in mouse models.

These neurons affect how much you do, or don’t, want to eat

Neurons in the bed nucleus of the stria terminalis (BNST) appear to regulate food intake. The neurons appear to form part of a network that controls appetite loss in mice.

Researchers identify new hunger pathway in the brain

Newly identified network in the hypothalamus alters feeding behaviors on a shorter timescale. The pathway affects food intake and body weight by releasing GABA, which may occur due to the detection, and not the consumption of food.

Body parts respond to day and night independently from brain

Skin and liver cells appear to have their own circadian clock. Both the liver and skin respond to changes in light and maintain critical function, independent of the brain's circadian rhythm.

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.
