The goals of this project were threefold: to determine the nature of the memory deficit in children/adolescents with dyslexia, to utilize clinical memory measures in this endeavor, and to determine the extent to which semantic short-term memory (STM) is related to basic reading performance. Two studies were conducted using different samples, one incorporating the Wide Range Assessment of Memory...

The authors examined the nature of the working memory deficit in persons with Parkinson's disease (PD). Three hypotheses were tested: a limited storage capacity, an impaired executive component, and a reduction of psychomotor speed. Verbal working memory was assessed in 14 PD patients without dementia and 14 matched control participants. Participants were administered a classical verbal span te...

In the present study, the effect of minocycline was studied against intracerebroventricular streptozotocin induced spatial memory deficit. Male wistar rats were injected with intracerebroventricular streptozotocin bilaterally. The rats were treated chronically with Minocycline (10, 20 and 40 mg/kg, ip) for 17 days starting from day 1 of streptozotocin injection in separate groups. The spatial m...

We have shown previously that electrolytic lesions of the dorsal hippocampus (DH) produce a severe deficit in contextual fear if made 1 d, but not 28 d, after fear conditioning (). As such, the hippocampus seems to play a time-limited role in the consolidation of contextual fear conditioning. Here, we examine retrograde amnesia of contextual fear produced by DH lesions in a within-subjects desi...

Control and Schizophrenic subjects performed memory tests under conditions in which performance is influenced by newly acquired information about associations between pairs of normatively unrelated words (a 'context' word and a target word). In Experiment 1, the associative memory test was implicit. Control and schizophrenic subjects reached the same level of performance and, more importantly, ...

The reduced verbal long-term memory capacities often reported in dyslexics are generally interpreted as a consequence of their deficit in phonological coding.The present study was aimed at evaluating whether the learning deficit exhibited by dyslexics was restricted only to the verbal component of the long-term memory abilities or also involved visual-object and visual-spatial domain. A further...

Centella asiatica extract on cognition and hippocampal pathology of mild chronic cerebral hypoperfusion (CCH) that was induced by permanent right common carotid artery occlusion (RCO) in rats. Materials and Methods: Sixty-four male Sprague-Dawley rats were randomly divided into four groups of Sham-veh, Sham-C. asiatica, RCO-veh and RCO-C. asiatica, which were further divided into short-term and...
