Internal-state-dependent control of feeding behavior via hippocampal ghrelin signaling

Alzheimer’s disease (AD) is an uncommon condition that usually occurs late in life, a condition where several metabolic factors were found to contribute to its onset and course. Peripheral tissue insulin resistance and pathologies observed in tau proteins were demonstrated through studies of diabetes employing streptozotocin-injected and db/db mouse models. In their study, Xiong et […]

Our brains regulate food intake depending on the availability of food and internal energy needs. However, Berger et al. (2024) sought to find out whether internal energy storage impacts the type of memory formed. In this study, the authors demonstrated that the length of starvation determines whether Drosophila melanogaster develops short-term appetitive memories or more […]
