Junk food orders up trouble for young brains

Everyone knows consuming junk food is bad for your health, but a new study reveals it could also be bad for developing brain health. Excessive consumption of calorie-dense foods can lead to changes in the structure and function of the prefrontal cortex, including altering dopamine signaling and inhibition.

Triglycerides control neurons in the reward circuit

Dietary triglycerides directly alter signaling in the reward circuit to regulate behavior. The findings reveal a potential mechanism by which triglyceride-rich diets may lead to adaptions in dopamine signaling that underlie reward deficit and compulsive behaviors.

Previously unappreciated neurotransmitter system in the brain discovered

Researchers have identified a novel neurotransmitter system in the brain. The system signals transmission of innate olfactory information to areas of the brain associated with emotional processing via the TAAR5 receptor. The findings could help in the development of new treatments for depression and schizophrenia.
