Physio question for #neuroskyence: This figure shows that global BOLD signal is already increasing before the onset of electrodermal spikes (t=0), and falls rapidly afterwards. I get the same pattern in my dataset (also for event-related analysis, GS peaks at t=0). What are potential explanations?

Revisiting Julian Jaynes, and this is something almost word-for-word that I often think about hypnosis. An aspiring global theory of cognitive or brain architecture needs to have something to say about it. Thoughts? #neuroskence #psychscisky

5HT-2A binds widely across the cortex, especially visual and prefrontal cortex. But, it does not bind in the midbrain and hindbrain (and binds to a lesser extent in the diencephalon).

In this example, according to Solms the patient got "full marks on the Glasgow Coma Scale". He also reports this conversation. So specifically he is 1) Awake 2) Responsive 3) Can communicate (and joke?), and 4) Reports having mental imagery

Mark Solms talks about a Patient W he had who had basically his entire frontal lobes (apart from Broca's area) surgically removed as a teenager, due to repeated post-operational infections. This patient was fully conscious (in the responsiveness sense) and reported having mental imagery.

My dad told me to watch Seven Samurai to 'understand the Japanese ethos'. Epic sentence, no idea how correct it is. Amazing movie either way.
