Study Reveals Brain’s Thalamus Role in Hunger-Driven Motivation
Researchers have made a significant breakthrough in understanding the brain’s thalamus and its role in hunger-driven motivation. A recent study conducted with mice has shed light on the involvement of two distinct neuronal populations within the paraventricular nucleus (PVT) in regulating actions aimed at achieving a goal, such as foraging for food. The study revealed that dopamine D2 receptor-positive (PVTD2(+)) neurons play a pivotal role in amplifying motivation and pursuit behaviors, while their counterparts, PVTD2(–) neurons, are linked to action termination. This discovery challenges previous assumptions about the uniformity of the PVT and underscores its critical function in translating hunger into motivated action. The findings hold promise for the development of new treatments for motivation-related psychiatric conditions.
Middle-Age Obesity Linked to Changes in Brain Neurons, Japanese Study Finds
Recent research from Japan has uncovered a fascinating link between middle-age obesity and changes in brain neuron shape, with potential implications for humans. The study focused on the impact of a protein called melanocortin-4 (MC4R) on obesity in rats, revealing that MC4R accumulates in primary cilia, affecting metabolism and fat-burning ability. The findings offer valuable insights into the complex relationship between neuronal shape and obesity, potentially paving the way for innovative approaches to weight management and metabolic health.
