A Double Dissociation between Hippocampal Subfields Differential Time Course of CA3 and CA1 Place Cells for Processing Changed Environments
Computational theories have suggested different functions for the hippocampal subfields (e.g., CA1 and CA3) in memory. However, it has been difficult to find dissociations relevant to these hypothesized functions in investigations of the hippocampal correlates of space ("place fields") in freely behaving animals. The current study demonstrates a double dissociation between the shifts in the cen...
متن کاملFrontal-hippocampal double dissociation between normal aging and Alzheimer's disease.
Controversy persists regarding whether Alzheimer's disease (AD) is a distinct entity or instead exists on a continuum with nondemented aging. To explore this issue, volumetric analyses of callosal and hippocampal regions were performed on 150 participants aged 18-93 years. Group-level analyses revealed that nondemented age-related differences were greater in anterior than posterior callosal reg...
متن کاملDouble dissociation between hippocampal and parahippocampal responses to object-background context and scene novelty.
Several recent models of medial temporal lobe (MTL) function have proposed that the parahippocampal cortex processes context information, the perirhinal cortex processes item information, and the hippocampus binds together items and contexts. While evidence for a clear functional distinction between the perirhinal cortex and other regions within the MTL has been well supported, it has been less...
متن کاملNeuropsychological Double Dissociation between Linguistic Levels: Clinical Linguistic Evidence from Iranian Aphasic Patients
Introduction: In this paper we report on clinical linguistic applications of several versions of the Bilingual Aphasia Test (BAT) and the Persian Aphasia Battery (PAB) developed to assess patterns of recovery and language impairments in monolingual and bilingual aphasics with different clinical histories living in Iran. Methods: The participants are adult monolingual native speakers of Persian ...
متن کاملA double dissociation between impact factor and cited half life.
ratio between the number of citations in a given year to any item published in that journal in the previous two years and the number of research items published in the same journal in the same two years. IF, widely acknowledged as the standard measure for scientific quality, places great emphasis on current research, favouring fast moving disciplines, while penalising slower moving topics; the ...
