Thesis (Ph.D.)--Boston University / The present research stemmed from (a) Mayer's finding that there is no generalization between contralateral sites in the visual cortex of the albino rat (when the sites were stimulated by way of implanted electrodes, one being used as a conditioned stimulus, the other as a test stimulus in order to measure the extent of generalization); (b) anatomical data on the visual cortex, e.g., Nauta and Bucher's finding of rich inter-connections among the cells of the visual cortex of the same side (in the rat), and similar findings by Sholl with regard to the cat; and (c) the work of Myers, who found (with cats) that interocular transfer always appears unless both the posterior corpus callosum and the decussating fibers of the optic chiasm are cut. If (1) generalization between the activity of different parts of the brain on intact neural inter-connections between these areas (as suggested by Myers' research) and (2) cells in the ipsilateral visual cortex of rats are richly interconnected (as Nauta and Bucher,report}, then one should expect substantial generalization from one site in the visual cortex to another on the same side [TRUNCATED].
