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

The genetically specified neuronal subtypes and projections that control alcohol consumption and other affective disorders are not fully understood, although the central nucleus of the amygdala plays a crucial role in these behaviors. In this study by Torruella-Suárez et al. (2020), the authors demonstrate that in vivo ethanol intake activates neurotensin neurons in the central […]

While it has been previously shown that short-term fatty diets can cause impairments in hippocampal cognitive function, this 2019 study examined whether morphological and functional changes in microglia are responsible for this effect. Microglia in the hippocampus are vulnerable to the impact of aging and have displayed hyper-responsiveness to various stimuli. This animal-based study fed […]
