Journal Club

The journal club of next week  (15:feb:2010) will be presented by Ken and Mehdi and it will treat on bayesian inference in the brain. Attached here is the reference paper of Friston. The presentation will be in the conference room at 12h30

This week the journal club will be about the presence of Zn specificly in feedback pathways. The paper is sent via e mail. The JC will be in the conference room at 12h30 on dec 9th.

The resurgent science of consciousness has been accompanied by a recent emphasis on the problem of measurement. Having dependable measures of consciousness is essential both for mapping experimental evidence to theory and for designing perspicuous experiments. Here, we review a series of behavioural and brain-based measures, assessing their ability to track graded consciousness and clarifying how they relate to each other by showing what theories are presupposed by each. We identify possible and actual conflicts among measures that can stimulate new experiments, and we conclude that measures must prove themselves by iteratively building knowledge in the context of theoretical frameworks. Advances in measuring consciousness have implications for basic cognitive neuroscience, for comparative studies of consciousness and for clinical applications.

This week's journal club will be on a paper from Moeller.

Dear all next thursday Manu is presenting a jurnal club on DTI.

Next thursday Julian will be pleased to present us a recent paper from Ekstrom and all.

Nex Mehdi will be pleased to present us the recent paper of Roesch on the role of dopamine in the coding of the optimal goal directed action.

This summer a very interesting paper came out in Science showing that
electrical stimulation of the frontal eye field can directly modulate
the activity of area V4 but not area V1. The modulation of activity in
area V1 needed a concomitant visual stimulus. The results of this paper
are of large importance to our interpretation of cortical feedback and
hierarchy but some of the interpretations are wrong knowing our data on
cortico -cortical connections.
