Below is a link to the forthcoming BBS target article: Separate Visual Representations in the Planning and Control of Action by Scott Glover http://www.bbsonline.org/Preprints/Glover/Referees/ This article has been accepted for publication in Behavioral and Brain Sciences (BBS), an international, interdisciplinary journal providing Open Peer Commentary on important and controversial current research in the biobehavioral and cognitive sciences. Commentators must be BBS Associates or suggested by a BBS Associate. To be considered as a commentator for this article, to suggest other appropriate commentators, or for information about how to become a BBS Associate, please reply by EMAIL within three (3) weeks to: calls(a)bbsonline.org The Calls are sent to 10,000 BBS Associates, so there is no expectation (indeed, it would be calamitous) that each recipient should comment on every occasion! Hence there is no need to reply except if you wish to comment, or to suggest someone to comment. If you are not a BBS Associate, please approach a current BBS Associate (there are currently over 10,000 worldwide) who is familiar with your work to nominate you. All past BBS authors, referees and commentators are eligible to become BBS Associates. An electronic list of current BBS Associates is available at this location to help you select a name: http://www.bbsonline.org/Instructions/assoclist.html (please note that this list is being updated) If no current BBS Associate knows your work, please send us your Curriculum Vitae and BBS will circulate it to appropriate Associates to ask whether they would be prepared to nominate you. (In the meantime, your name, address and email address will be entered into our database as an unaffiliated investigator.) ======================================================================= ** IMPORTANT ** ======================================================================= To help us put together a balanced list of commentators, it would be most helpful if you would send us an indication of the relevant expertise you would bring to bear on the paper, and what aspect of the paper you would anticipate commenting upon. (Please note that we only request expertise information in order to simplify the selection process.) Please DO NOT prepare a commentary until you receive a formal invitation, indicating that it was possible to include your name on the final list, which is constructed so as to balance areas of expertise and frequency of prior commentaries in BBS. To help you decide whether you would be an appropriate commentator for this article, an electronic draft is retrievable at the URL that follows the abstract and keywords below. ======================================================================= ======================================================================= Separate Visual Representations in the Planning and Control of Action Scott Glover University of Oxford ABSTRACT: Evidence for a dichotomy between the planning of an action and its on-line control in humans is reviewed. This evidence suggests that planning and on-line control each serve a specialized purpose different from the other, and utilize distinct visual representations. Evidence from behavioral studies suggests that planning is influenced by a large array of visual and cognitive information, whereas control is influenced solely by the spatial characteristics of the target, including such things as its size, shape, orientation, etc. Evidence from brain imaging and neuropsychology suggest that planning and control are subserved by separate visual centers in the posterior parietal lobes, each constituting part of a larger network for planning and control. Planning appears to rely on phylogenetically newer regions in the inferior parietal lobe, along with the frontal lobes and basal ganglia, whereas control appears to rely on older regions in the superior parietal lobe, along with the cerebellum.

BBS's new expanded page quota will make it possible for us to increase the number of books we treat per year, so this is an excellent time for BBS Associates and biobehavioral/cognitive scientists in general to nominate books you would like to see accorded BBS multiple book review. (Authors may self-nominate, but books can only be selected on the basis of multiple nominations.) It would be very helpful if you indicated in what way a BBS Multiple Book Review of the book(s) you nominate would be useful to the field (and of course a rich list of potential reviewers would be the best evidence of its potential impact!). *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* Please note: Your email address has been added to our user database for Calls for Commentators, the reason you received this email.
