Based on the similarity of brain areas lesioned in neglect and those activated by spatial working memory (WM) tasks in normals, we hypothesized that neglect may involve spatial WM impairments. A left neglect patient with right inferior frontal and basal ganglia damage performed cancellation tasks, making either highly visible marks (to provide a reminder of visited items), or invisible marks (s...
Memory performance can be enhanced by expectations regarding the appearance of ensuing stimuli. Here, we investigated the influence of stimulus-category expectation on memory performance in aging, and used fMRI to explore age-related alterations in associated neural mechanisms. Unlike younger adults, who demonstrated both working memory (WM) and long-term memory (LTM) performance benefits for f...
We describe a patient who developed topographical memory loss after a closed head injury. His symptoms and the psychological test results indicate a selective deficit of topographical memory, his perceptual and spatial skills being relatively unimpaired.
the plethora of studies indicated that there is a cross talk relationship between harmaline and serotonergic (5-ht) system on cognitive and non-cognitive behaviors. thus, the purpose of this study is assessment the effects of ca1 5-ht4 receptor on memory acquisition deficit induced by harmaline. harmaline was injected peritoneally, while 5-ht4 receptor agonist (rs67333) and antagonist (rs23597-...
Aims:Memory deficit is the most visible symptom of cerebral ischemia. The hippocampus is sensitive against cerebral ischemia. Oxidative stress and inflammation are involved in the pathological process after cerebral ischemic injury. Paroxetine has anti-oxidative and anti-inflammatory effects. In this study the effect of paroxetine on memory deficit after cerebral ischemia was investigated. Meth...
Handwriting is fundamental in school and everyday life situations. Legibility guarantees that writing productions communicate information, and speed is often crucial, especially in children with attention deficit and hyperactivity disorder (ADHD), in order to increase the likelihood of their being able to work efficiently and stay on-task during school activities. Preliminary reports have shown...
Introduction: Previous studies have shown that seizure can induce cognitive impairment. On the other hand, soy phytoestrogens, which are mainly found in soybean (Glycine max (L.) Merr.), have beneficial effects on the nervous system. However, little is known about their probable effects on seizure. The present study aimed to examine the probable effects of soy extract, containing the phytoestro...
Introduction: Alzheimer disease is a progressive and irreversible neuropsychiatric disorder. Melissa Officinalis improves anxiety and clinical dementia symptoms caused by AD therefore, the purpose of the present study was to evaluate the effect of Mellisa extract on spatial memory deficit induced by STZ in MWM examination of male wistar rats. Methods: In the present study, 112 male wista...
OBJECTIVES A deficit in facial emotion recognition was described in patients with Alzheimer disease (AD). However, this issue has been underexplored in subjects with amnestic mild cognitive impairment (a-MCI). Thus, the authors aimed to determine whether a deficit in facial emotion recognition is present in a-MCI phase and whether this is intensity dependent. A secondary aim was to investigate ...
BACKGROUND Chronic pain is often accompanied by short-term memory deficit and depression. Currently, it is believed that short-term memory deficit and depression are consequences of chronic pain. Here, we test the hypothesis that the symptoms might be caused by overproduction of interleukin-1beta (IL-1β) in the injured nerve independent of neuropathic pain following spared nerve injury in rats ...
