  • Title: Rats with fimbria-fornix lesions can acquire and retain a visual-tactile transwitching (configural) task.
    Author: Whishaw IQ, Tomie JA.
    Journal: Behav Neurosci; 1995 Aug; 109(4):607-12. PubMed ID: 7576204.
    Abstract:
    The idea that the hippocampus is essential for acquisition and retention of a transwitching (configural) problem is evaluated with a visual-tactile task. The task requires the rats to pull up a string of one of two sizes for food, as signalled by room lighting conditions. Rats received cathodal fimbria-fornix lesions either prior to or after learning the task. Rats with fimbria-fornix lesions were unimpaired in acquisition or retention. The results do not support the position that the hippocampal formation is essential for the acquisition and retention of a transwitching configural problem. The result is discussed in relation to the configural theory of hippocampal function.
