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.
New Study Suggests Fat Droplets in Brain Cells May Be Key to Fighting Alzheimer’s

Study Identifies Neuronal Circuit for Vocalization and Respiratory Coordination in Mice
Discover the key neuronal circuit responsible for coordinating vocalization and respiration in mice. Learn how vocalization-specific laryngeal premotor neurons in the retroambiguus nucleus (RamVOC) drive vocal cord closure and coordinate expiration effort and sound production. Gain valuable insights into the neural mechanisms underlying vocal-respiratory coordination and the prioritization of breathing during vocalization.
Key Protein Identified in Development of Alzheimer’s Disease
Scientists have discovered a key protein, Mdm2, in the development of Alzheimer’s disease that, when blocked, could potentially slow or halt the condition’s progress. This discovery was made through tests on mice, where deactivating Mdm2 stopped the destruction of dendritic spines and synapses, crucial for brain cell communication. Understanding the role of Mdm2 in Alzheimer’s progression could be crucial in developing treatments for the disease.
