Comparison of the Basal Ganglia and Cerebellum in Shifting Attention.
April 1, 2001... Abstract * The basal ganglia and cerebellum have traditionally been associated with motor performance. Recently, there has been considerable interest regarding the contributions of these subcortical structures to aspects of cognition. In...

Temporal Allocation of Visual Attention in Adult Attention Deficit Hyperactivity Disorder.
April 1, 2001... Abstract * In two experiments, we examined the ability of adults with attention deficit hyperactivity disorder (ADHD) to process multiple targets appearing in a rapid serial visual presentation (RSVP) stream. Using a standard attentional...

Motor Cortical Activity during Interception of Moving Targets.
April 1, 2001... Abstract * The single-unit activity of 831 cells was recorded in the arm area of the motor cortex of two monkeys while the monkeys intercepted a moving visual stimulus (interception task) or remained immobile during presentation of the...

Neuronal Clusters in the Primate Motor Cortex during Interception of Moving Targets.(Statistical Data Included)
April 1, 2001... Abstract * Two rhesus monkeys were trained to intercept a moving target at a fixed location with a feedback cursor controlled by a 2-D manipulandum. The direction from which the target appeared, the time from the target onset to its...

Preserved Adjustment but Impaired Awareness in a Sensory-Motor Conflict following Prefrontal Lesions.
April 1, 2001... Andrea Slachevsky [1,2] Bernard Pillon [1,2] Pierre Fourneret [3] Pascale Pradat-Diehl [2] Marc Jeannerod [3] Bruno Dubois [1,2] Abstract * Control of action occurs at different stages of the executive process,...

No Right to Speak? The Relationship between Object Naming and Semantic Impairment: Neuropsychological Evidence and a Computational Model.
April 1, 2001... M. A. Lambon Ralph [1] J. L. McClelland [2] K. Patterson [3] C. J. Galton J. R. Hodges [3, 4] Abstract * The processes required for object naming were addressed in a study of patients with semantic dementia (a...

Preserved Recognition in a Case of Developmental Amnesia: Implications for the Acquisition of Semantic Memory?
April 1, 2001... Alan Baddeley [1] Faraneh Vargha-Khadem [2] Mortimer Mishkin [3] Abstract * We report the performance on recognition memory tests of Jon, who, despite amnesia from early childhood, has developed normal levels of performance...

Procedural Learning in Broca's Aphasia: Dissociation between the Implicit Acquisition of Spatio-Motor and Phoneme Sequences.
April 1, 2001... Thomas Goschke [1] Angela D. Friederici [2] Sonja A. Kotz [2] Anja van Kampen [3] Abstract * Procedural learning of spatio-motor and phoneme sequences was investigated in patients with Broca's and Wernicke's aphasia and...

Interconnected Large-Scale Systems for Three Fundamental Cognitive Tasks Revealed by Functional MRI.
April 1, 2001... Abstract * The specific brain areas required to execute each of three fundamental cognitive tasks--object naming, same--different discrimination, and integer computation--are determined by whole-brain functional magnetic resonance imaging...

Encoding Processes during Retrieval Tasks.
April 1, 2001... Abstract * Episodic memory encoding is pervasive across many kinds of task and often arises as a secondary processing effect in tasks that do not require intentional memorization. To illustrate the pervasive nature of information...

Comment on "Electrophysiological Correlates of Conscious Vision: Evidence from Unilateral Extinction" by Marzi, Girelli, Miniussi, Smania, and Maravita, in JOCN 12:5.(Journal of Cognitive Neuroscience, September 2000)
April 1, 2001... In their paper "Electrophysiological correlates of conscious vision: Evidence from unilateral extinction," published in the September 2000 issue of this journal, Marzi et al. report a single-case study of a patient suffering from marked...
