Scientific approach towards the neuronal mechanisms of conscious experience. Includes neurophysiology, imaging, psychophysics, and theory.
This paper quite convincingly shows that the induced gamma band response recorded from scalp-EEG is an artifact of microscaades. I highly recommend this paper to everybody who has read, cited, or published (!) any papers reporting gamma band response using scalp-EEG. This paper is likely to be a must read in this research domain in the near future. The paper is very clearly written. I also recommend to read Pascal Fries' commentary in the same issue ("Finding Gamma" Pascal Fries,1,2,∗ René Scheeringa,1 and Robert Oostenveld1) and the replies from the people who published many papers reporting gamma band response with scalp-EEG (http://www.neuron.org/content/article/comments?uid=PIIS0896627308003012).
Madoka will present a study looking at synchrony between two brains aka "interpersonal EEG" as a prelude to future studies.
Prior to Madoka's presentation, I'd like to have a 5 min debriefing on the data John Reynold's presented today (narrow/broad spiking and cell type) since these have direct implications for LFP recordings and EEG - especially w.r.t gamma band...
See you all then!

Hi all,
I'm planning to present three interesting papers from recent issues of Nature and Science.
1. Deep stimulation to thalamus to awaken an unconscious patient
2. Experimental induction of out-of-body experiences.
If you are interested (and if you're a morning person!), you are welcomed to join the Journal club.
It is held in room 50 (MRI conference room) in Broad from 8:30-9:30 AM.
Cheers
Nao

Tots More Socially Cognitive Than Apes
By LAURAN NEERGAARD – Sep 6, 2007
WASHINGTON (AP) — Toddlers may act up like little apes, but researchers who compared the species concluded a 2-year-old child still has the more sophisticated social learning skills.
In one test, preschoolers who wanted a toy hidden in a trick tube intently copied a scientist's movements to retrieve the prize. Chimps watched the lesson, but then mostly tried to smash or bite open the tube. When it came to simple math, however, the apes seemed to know more than the youngsters, apparently "adding" how many tasty raisins researchers had hidden.
In a novel study, scientists lured 106 chimpanzees, 32 orangutans and 105 toddlers to sit thro ... read more
