Hyporesponsive Reward Anticipation in the Basal Ganglia following Severe Institutional Deprivation Early in Life
Journal of Cognitive Neuroscience - Tập 22 Số 10 - Trang 2316-2325 - 2010
Mitul A. Mehta, Emma Gore-Langton, Nicole I. Golembo, Emma Colvert, Steven Williams, Edmund Sonuga‐Barke
AbstractSevere deprivation in the first few years of life is associated with multiple difficulties in cognition and behavior. However, the brain basis for these difficulties is poorly understood. Structural and functional neuroimaging studies have implicated limbic system structures as dysfunctional, and one functional imaging study in a heterogeneous group of maltreated individuals has confirmed ... hiện toàn bộ
Causal Role of the Sensorimotor Cortex in Action Simulation: Neuropsychological Evidence
Journal of Cognitive Neuroscience - Tập 23 Số 8 - Trang 2068-2078 - 2011
Barbara Tomasino, Miran Škrap, Raffaella I. Rumiati
Abstract Interest in sensorimotor cortex involvement in higher cognitive functions has recently been revived, although whether the cortex actually contributes to the simulation of body part movements has not yet been established. Neurosurgical patients with selective lesions to the hand sensorimotor representation offer a unique opportunity to demonstrate that the sensorimotor cortex plays a causa... hiện toàn bộ
When Peanuts Fall in Love: N400 Evidence for the Power of Discourse
Journal of Cognitive Neuroscience - Tập 18 Số 7 - Trang 1098-1111 - 2006
Mante S. Nieuwland, Jos J. A. Van Berkum
Abstract In linguistic theories of how sentences encode meaning, a distinction is often made between the context-free rule-based combination of lexical-semantic features of the words within a sentence (“semantics”), and the contributions made by wider context (“pragmatics”). In psycholinguistics, this distinction has led to the view that listeners initially compute a local, context-independent mea... hiện toàn bộ
The Electrophysiological Signature of Remember–Know Is Confounded with Memory Strength and Cannot Be Interpreted as Evidence for Dual-process Theory of Recognition
Journal of Cognitive Neuroscience - Tập 29 Số 2 - Trang 322-336 - 2017
Noam Brezis, Zohar Z. Bronfman, Galit Yovel, Yonatan Goshen‐Gottstein
Abstract The quantity and nature of the processes underlying recognition memory remains an open question. A majority of behavioral, neuropsychological, and brain studies have suggested that recognition memory is supported by two dissociable processes: recollection and familiarity. It has been conversely argued, however, that recollection and familiarity map onto a single continuum of mnemonic stre... hiện toàn bộ
Indelibility of Subcortical Emotional Memories
Journal of Cognitive Neuroscience - Tập 1 Số 3 - Trang 238-243 - 1989
Joseph E. LeDoux, Lizabeth M. Romanski, Andrew Xagoraris
Abstract Acquisition and extinction of fear responses conditioned to a visual stimulus were examined in rats with ablations of visual cortex. Visual cortex lesions did not interfere with acquisition, indicating that visual fear conditioning, like auditory fear conditioning, is mediated by sub-cortical, probably thalamo-amygdala, sensory pathways. In contrast to acquisition, extinction was greatly ... hiện toàn bộ
Progressive Nonfluent Aphasia: Language, Cognitive, and PET Measures Contrasted with Probable Alzheimer's Disease
Journal of Cognitive Neuroscience - Tập 8 Số 2 - Trang 135-154 - 1996
Murray Grossman, Jenifer Mickanin, Kris Onishi, Elizabeth M. Hughes, Mark D’Esposito, Ding Xin-sheng, Abass Alavi, Martin Reivich
Abstract The purpose of this study was to compare the language and cognitive profiles of four progressive nonfluent aphasia (PNFA) patients with 25 probable Alzheimer's disease (pAD) patients, and to identify the distinct cortical defects associated with cognitive deficits in PNFA using positron emission tomography (PET). Longitudinal observations of PNFA patients revealed progressively telegraphi... hiện toàn bộ
Retrieval Success is Accompanied by Enhanced Activation in Anterior Prefrontal Cortex During Recognition Memory: An Event-Related fMRI Study
Journal of Cognitive Neuroscience - Tập 12 Số 6 - Trang 965-976 - 2000
Kathleen B. McDermott, Todd C. Jones, Steven E. Petersen, Sarah K. Lageman, Henry L. Roediger
Abstract Neural regions associated with retrieval success were identified using event-related fMRI procedures and randomly ordered trials on a recognition memory test. Differences between hits and correct rejections (CRs) occurred in multiple regions, including bilateral anterior and right dorsolateral prefrontal cortex, bilateral inferior parietal cortex, and right superior parietal cortex (all h... hiện toàn bộ
Neural Correlates of Confidence during Item Recognition and Source Memory Retrieval: Evidence for Both Dual-process and Strength Memory Theories
Journal of Cognitive Neuroscience - Tập 23 Số 12 - Trang 3959-3971 - 2011
Scott M. Hayes, Norbou Buchler, Jared Stokes, James E. Kragel, Roberto Cabeza
Abstract Although the medial-temporal lobes (MTL), PFC, and parietal cortex are considered primary nodes in the episodic memory network, there is much debate regarding the contributions of MTL, PFC, and parietal subregions to recollection versus familiarity (dual-process theory) and the feasibility of accounts on the basis of a single memory strength process (strength theory). To investigate these... hiện toàn bộ
Further Dissociating the Processes Involved in Recognition Memory: An fMRI Study
Journal of Cognitive Neuroscience - Tập 17 Số 7 - Trang 1058-1073 - 2005
Richard N. Henson, Michael Hornberger, Michael D. Rugg
Abstract Based on an event-related potential study by Rugg et al. [Dissociation of the neural correlates of implicit and explicit memory. Nature, 392, 595-598, 1998], we attempted to isolate the hemodynamic correlates of recollection, familiarity, and implicit memory within a single verbal recognition memory task using event-related fMRI. Words were randomly cued for either deep or shallow process... hiện toàn bộ
When Far Becomes Near: Remapping of Space by Tool Use
Journal of Cognitive Neuroscience - Tập 12 Số 3 - Trang 415-420 - 2000
Anna Berti, Francesca Frassinetti
Abstract Far (extrapersonal) and near (peripersonal) spaces are behaviorally defined as the space outside the hand-reaching distance and the space within the hand-reaching distance. Animal and human studies have confirmed this distinction, showing that space is not homogeneously represented in the brain. In this paper we demonstrate that the coding of space as “far” and “near” is not only determin... hiện toàn bộ
