Detecting individual memories through the neural decoding of memory states and past experience. Rissman J (2010) Proc Natl Acad Sci U S A.Login or register to post commentsI'll come, thanks, Igor - Igor Kagan (Caltech) May 31, 2010 Comment deletedI can't make it, but I'm pretty interested in the discussion on this article. It seems a bit too good to be true, I haven't scrutinized the methods yet but we're talking about classifying data from an event-related paradigm here... and to be able to do 75% correct on a subjective memory task leaves me dubious. Please post a summary of the discussion, if possible. - Julien Dubois (Caltech) June 1, 2010 Comment deleted - Login or register to post comments

Sweta Agrawal will be presenting two papers. Please RSVP by Tuesday evening if you'd like to attend.
We have all heard at one time or other about place/spatial memory work done in mice, and the role of the hippocampus in this type of memory. However, relatively recently, many scientists have begun looking at the same question in Drosophila. I thought looking over these articles might bring up some interesting questions like what exactly is place memory, how valid is the paradigm being used with Drosophila, and do insects process spatial information in any way that is similar to vertebrates?

Erik Schomburg will be presenting "Impact of spikelets on hippocampal CA1 pyramidal cell activity during spatial exploration". Please RSVP by Tuesday evening if you'd like to attend.
Note from Erik: "This study looks interesting to me because it looks at how subthreshold membrane activity, which has been difficult to observe experimentally, correlates with behavior and the spatial map, and how this drives the spiking activity."

Teaser: These two papers explore hearing in insects. This little-discussed modality provides an interesting case study of sensory transduction and its behavioral consequences.

Dominic Rizzo will be presenting three short papers. Please RSVP by Tuesday evening if you'd like to attend.
Teaser:
I'm going to cover a set of three papers with the common theme of embedded intelligence. They're each pretty short, but taken cumulatively point at some interesting correlations between concrete experiences and how they impact our perception of abstract ideas like value.Moving Through Time.

Xoana Troncoso will be presenting "Changes of mind in decision-making". Please RSVP by Tuesday evening if you'd like to attend.
From "Faculty of a 1000":
"This study presents interesting findings suggesting that human subjects can change their minds after making an initial decision about which arm movement to perform by continuing to process previously acquired sensory evidence about action choices that is still in the central processing "pipeline", even if no new sensory evidence is available from the environment after the initiation of the movement."
