Ghrelin and orexin interact to increase meal size through a descending hippocampus to hindbrain signaling pathway

Since microglia in the hippocampus are vulnerable to the effects of ageing, Spencer et al. (2019) assesses if the morphological and functional changes in microglia explain the findings from their previous studies showing short-term high-fat diets (HFD) significantly impairing hippocampal- and amygdala- based cognitive function only in the ageing and not in the young rats.

Using data on individuals from the UK Biobank (n = 6001) categorized by sex, ranging in age from 40 to 73, an online computerized 24-hour […]
