A second model, derived by Lepage et al. (Hippocampus 1998; 8:313 - 322) from their review of 52 PET studies, has suggested that the anterior hippocampus is activated by memory encoding while the posterior hippocampus is activated by memory retrieval.

But there's been a few studies that suggest the anterior hippocampus, a sub-region located at the front, could play a role in emotional regulation, including anxiety.

Fear, an emotion we have inherited from our ancestors, is not an abstract or intangible sense of imminent danger: it is expressed in neurochemical terms in our amygdala, the almond - shaped structure on the medial temporal lobe, anterior to the hippocampus.

The study found that under psilocybin, activity in the more primitive brain network linked to emotional thinking became more pronounced, with several different areas in this network — such as the hippocampus and anterior cingulate cortex — active at the same time.

Specifically, males on average had larger volumes and higher tissue densities in the left amygdala, hippocampus, insular cortex, putamen; higher densities in the right VI lobe of the cerebellum and in the left claustrum; and larger volumes in the bilateral anterior parahippocampal gyri, posterior cingulate gyri, precuneus, temporal poles, and cerebellum, areas in the left posterior and anterior cingulate gyri, and in the right amygdala, hippocampus, and putamen.

The medial septal area projects to a large number of brain regions that show theta modulation, including all parts of the hippocampus as well as the entorhinal cortex, perirhinal cortex, retrosplenial cortex, medial mamillary and supramamillary nuclei of the hypothalamus, anterior nuclei of the thalamus, amygdala, inferior colliculus, and several brainstem nuclei (Buzsáki, 2002).
