Around 22:35 the graph shows decreased efficiency in the experimental group, but the narration says that those in the experimental group are much more efficient. What's going on in this graph?

Thank you )

In the minute 5:29, when you speak about NE, it says that blocking it can decrease ALERTING and increasing it will increase WARNING signals, is alerting and warning synonims in this case?

[@hahar18]

yes

Thank you so much for this clear overview! I was just reading the updated review from Posner (2012) and this really helped to consolidate the information. Are you per chance aware of the role of dopamine within the alerting network? I am looking into the effect of arousal level on motor control in Parkinson’s disease, and can’t seem to find helpful sources. Could you recommend me any studies to read?

[@PaulMerritt]

Not off hand I am working on a lecture on motor learning so I'll take a look

[@anouktosserams]

Paul Merritt very much appreciated!

Many confuse the contents of consciousness with consciousness itself, the main theory is that of neuronal networks, mainly because people think the brain is mainly composed of neurons & networks sounds more specific & knowledgeable than "it's neurons!", however I would suggest that the Glial network is a better candidate for consciousness, whilst the neuronal network a better candidate for the contents of consciousness, my reasoning is thus: when people meditate their brain waves phase lock with the first peak frequency of the Schumann resonance at theta 7.8 htz, according to Robert Becker in "The Body Electric", the Glial system which utilizes an analogue semi-conductive flow of holes which because of their relative slow movement, are affected by external magnetic fields via the transverse Hall effect. My contention is that it's the magnetic component of the Schumann resonance that's affecting the holes in the Glial cells & therefore the brain waves, further I believe that when the Glial operate on neurons voluntary attention is at work,whilst when neurons affect the Glial cells involuntary attention is happening.

Very cool information. Tbh though, I sense a lack of enthusiasm in this presentation. I made it to 8 minutes.
