A 2026 rat study found that foot-shock stress transiently reduced food-cue approach during the first 2 conditioned-stimulus trials (t = 2.807; P < 0.05), and inhibiting the nucleus of the solitary tract weakened that stress effect.1 The useful finding is selective: stress used an NTS-linked route to dampen cue-evoked VTA dopamine, while outcome-specific satiety reduced ...
In the quest to find more effective treatments for depression, particularly the challenging symptom of anhedonia, Transcranial Direct Current Stimulation (tDCS) emerges as a promising option. This non-invasive brain stimulation technique targets specific brain regions to modulate activity and potentially alleviate symptoms. A recent study has shed light on the efficacy and safety of targeting …
Should you blame your brain if you don’t have the motivation to go to the gym and exercise? A recent discovery published in The Journal of Neuroscience will support those putting blame on their brains. Researchers in this particular study discovered that a tiny region of the brain called the “dorsal medial habenula” may be …
