Kedves Kollegak,
Prof. Ilkka Niiniluoto, a helsinki egyetemrol, ezen a heten Pestre jon.
Talalkozni vele a BTK Logika tanszeken lehet (felemelet 23. vagy 24.),
pentek du. 2-tol, egy informalis beszelgetesen. (Nem volt mod arra,
hogy eloadast szervezzunk neki; o kerte, hogy ilyen formaban szeretne
magyar kollegakkal talalkozni.) Akit a tudomanyfilozofia (foleg formalisabb
agai) erdekelnek, kerem, jojjon el.

KEYWORDS: Cell assemblies; cerebral cortex; coordination; context;
dynamic binding; functional specialization; learning; neural
coding; neural computation; neuropsychology; reading; object
recognition; perception; self-organization; synaptic plasticity;
synchronization.
ABSTRACT: This research concerns forms of coding, processing and
learning that are common to many different cortical regions and
cognitive functions. Local cortical processors may coordinate their
activity by maximizing the transmission of information that is
coherently related to the context in which it occurs, thereby
forming synchronized population codes. In this coordination,
contextual field (CF) connections link processors within and
between cortical regions. The effects of CF connections are
distinct from those mediating receptive field (RF) input. CFs can
guide both learning and processing without becoming confused with
RF information. Simulations explore the capabilities of networks
built from local processors with both RF and CF connections.
Physiological evidence for CFs, synchronization, and plasticity in
RF and CF connections is described. Coordination via CFs is related
to perceptual grouping, the effects of context on contrast
sensitivity, amblyopia, implicit influences of color in
achromotopsia, object and word perception, and the discovery of
distal environmental variables and their interactions through
self-organization. In cortical computation there may occur a
flexible evaluation of relations between input signals by locally
specialized but adaptive processors whose activity is dynamically
associated and coordinated within and between regions through
specialized contextual connections.

To help you decide whether you would be an appropriate commentator for
this article, an electronic draft is retrievable by anonymous ftp from
ftp.princeton.edu according to the instructions below (the filename is
bbs.phillips). Please do not prepare a commentary on this draft.
Just let us know, after having inspected it, what relevant expertise
you feel you would bring to bear on what aspect of the article.
-------------------------------------------------------------
These files are also on the World Wide Web and the easiest way to
retrieve them is with Netscape, Mosaic, gopher, archie, veronica, etc.
Here are some of the URLs you can use to get to the BBS Archive:
http://www.princeton.edu/~harnad/bbs.htmlhttp://www.cogsci.soton.ac.uk/bbs/Archive/bbs.phillips.htmlftp://ftp.princeton.edu/pub/harnad/BBS/bbs.phillips
ftp://ftp.cogsci.soton.ac.uk/pub/bbs/Archive/bbs.phillips
gopher://gopher.princeton.edu:70/11/.libraries/.pujournals
To retrieve a file by ftp from an Internet site, type either:
ftp ftp.princeton.edu
or
ftp 128.112.128.1
When you are asked for your login, type:
anonymous
Enter password as queried (your password is your actual userid:
yourlogin(a)yourhost.whatever.whatever - be sure to include the "@")
cd /pub/harnad/BBS
To show the available files, type:
ls
Next, retrieve the file you want with (for example):
get bbs.phillips
When you have the file(s) you want, type:
quit
----------
Where the above procedure is not available there are two fileservers:
ftpmail(a)decwrl.dec.com
and
bitftp(a)pucc.bitnet
that will do the transfer for you. To one or the
other of them, send the following one line message:
help
for instructions (which will be similar to the above, but will be in
the form of a series of lines in an email message that ftpmail or
bitftp will then execute for you).
