In the psilocybin study, 15 healthy subjects received IV psilocybin and placebo on two separate occasions in a double--blind design. On each occasion they underwent a 12--minute resting state scan. The interaction between the infusion and hippocampal functional connectivity was analysed. Increases and decreases in connectivity were found, with decreases to the cortical nodes of the default mode network, and increases to the right insular.

It discusses a variety of criticisms from points of view within Husserlian phenomenology, and within cognitive science, and looks towards the philosophy of Martin Heidegger to provide a possible alternative grounding for radical embodiment theories of consciousness, with special attention to temporality. It may be possible to use Heidegger's ideas to inform a new kind of radical embodiment. Heidegger and the phenomenological reduction 32 Heidegger on time: Temporal idealism? 34
