1) J Cogn Neurosci: 3 structural mechanisms that had been hypothesized to underlie vsWM development during childhood were evaluated by simulating the model and comparing results to fMRI. It was concluded that inter-regional synaptic connection strength cause vsWM development. 2) J Integr Neurosci: Given the importance of fronto-parietal connections, we tested whether connection asymmetry affected resistance to distraction. We drew the conclusion that stronger frontal connections are beneficial. By comparing model results to EEG, we concluded that the brain indeed has stronger frontal-to-parietal connections than vice versa.

# This program moves files from a remote computer. If you have a subdirectory
# tree which is a copy of the subdirectory tree at dayhoff, files are
# tomatically moved to the subdirectory tree on your computer, and all
# names of search paths will be updated. Only UNIX.
#
# Arg 1: The name of the remote host
# Arg 2: The name of the series located in the frS catalog below
# Arg 3: The name relative to the frF catalog of the catalog in which the
#        simulation files are located
#(Arg 4: The location where the series file is to be placed relative to
#        the toS catalog, unless the path starts with '/' or '~', in
#        which case the path is absolute or relative to the home catalog.)
#
# Change path names according to your own path organization. See # CHANGE #
# below.
