How long does it take the brain to access short-term memory?

A recent paper in Neuroimage by Brandeis Neuroscience Ph. D. program alumnus Yigal Agam, Professor Robert Sekuler and coworkers attempts to answer the question. To identify the earliest neural signs of recognition memory, they used event related potentials collected from human observers engaged in a visual short term memory task.  Their results point to an initial feed-forward interaction that underlies comparisons between what is being current seen and what has been stored in memory.  The locus of these earliest recognition-related potentials is consistent with the idea that visual areas of the brain contribute to temporary storage of visual information for use in ongoing tasks. This study provides a first look into early neural activity that supports the processing of visual information during short-term memory.

James Hodge, a former postdoc from the Griffith lab here at Brandeis, is now running a lab at the University of Bristol in England. James is looking for a qualified postdoc to work on molecular mechanisms of synaptic plasticity and learning using Drosophila.
