          Smelling Food Triggers Fullness, But Only in Lean Brains

          Researchers have identified a new brain pathway in mice that links the smell of food to feelings of fullness—offering insight into how scent influences appetite. When lean mice smelled food, a group of nerve cells in the medial septum activated rapidly, signaling satiety and reducing food intake.

          How Obesity Rewires the Brain’s Food Reward Circuits

          A new research initiative is investigating how obesity reshapes brain circuits involved in reward, motivation, and emotion, potentially driving unhealthy food decisions. The cross-disciplinary team will use cutting-edge electrochemical techniques to measure real-time brain chemical responses to food-related stimuli in humans.

          Serotonin, GABA, and Dopamine Drive Hunger and Feeding

          A new study has revealed how brain circuits and neurotransmitters regulate meal initiation, offering insights into obesity management. Researchers identified serotonin neurons in the midbrain's dorsal Raphe nucleus (DRN) as key players, inhibited by GABA and dopamine when hunger strikes.

          Newly Discovered Brain Neurons May Help Curb Hunger

          Scientists have uncovered a new neuron type, BNC2, which acts quickly to counter hunger-promoting neurons, potentially leading to more effective appetite regulation. These BNC2 neurons, located in the brain’s arcuate nucleus, respond rapidly to hunger cues by inhibiting AGRP neurons responsible for driving appetite. This discovery adds a crucial layer to our understanding of the neural circuits controlling hunger and opens the door for novel treatments for obesity and metabolic conditions.

          Neural Circuit Found to Regulate Chewing and Appetite

          New research has uncovered a simple neural circuit that connects hunger signals to jaw movements required for eating. Scientists identified a three-neuron pathway involving the hormone leptin and BDNF neurons, which controls the jaw's motor function.

          Ozempic Boost Fullness Pre-Meal via Hypothalamus

          A new study shows GLP-1 receptor agonists increase pre-meal fullness by activating neurons in the dorsomedial hypothalamus. This mechanism helps prevent overeating, offering insights into obesity treatment. The research highlights how GLP-1 impacts food perception and hypothalamic responses to food cues, enhancing satiation before food intake.

          Brain’s Food-Seeking Circuit Overrides Hunger Signals

          Researchers identified a brain circuit in mice that drives them to seek food even when not hungry, focusing on a specific group of cells in the brainstem's periaqueductal gray (PAG) area. This discovery highlights how stimulating these cells causes mice to prefer high-calorie foods and engage in food-seeking behaviors, regardless of hunger.

          Eating with Your Eyes and Gut? How Your Brain Decides When to Eat

          The science of eating behavior goes beyond hunger cues; it involves sensory stimuli, internal signals, and the gut-brain connection. External cues like food packaging and advertisements influence our eating decisions, but internal signals, such as hunger and fullness, play a profound role.
