A review of a Nature Reviews Neuroscience paper, and then I just sortta wonder off and babble incessantly ... .
Nature publications generates some high quality reviews that are great for catching up on the latest developments in a given area. I've always had a bit of interest in the hippocampus so was pleased that Nature Reviews Neuroscience offered the extensive review article below for free(each month the Review series and I believe some other Nature journals offer free articles).
Article: A pathophysiological framework of hippocampal dysfunction in ageing and disease

Abstract | The hippocampal formation has been implicated in a growing number of disorders, from Alzheimer’s disease and cognitive ageing to schizophrenia and depression. How can the hippocampal formation, a complex circuit that spans the temporal lobes, be involved in a range of such phenotypically diverse and mechanistically distinct disorders? Recent neuroimaging findings indicate that these disorders differentially target distinct subregions of the hippocampal circuit. In addition, some disorders are associated with hippocampal hypometabolism, whereas others show evidence of hypermetabolism. Interpreted in the context of the functional and molecular organization of the hippocampal circuit, these observations give rise to a unified pathophysiological framework of hippocampal dysfunction.
