A system-level brain model of spatial working memory and its impairment
نویسنده
چکیده
A system-level model of spatial working memory is described, using the author’s computer science and logical modeling approach. The remembered mental image is located in a lateral parietal module, and plans are executed and sequenced in a dorsal prefrontal module. Mental images are saved and maintained by explicit messages from the currently executed plan and can be reinstated for use in motor control. By attenuating the goal, the plan fell below threshold, matching experimental results of Conklin et al. where schizophrenic and schizotypal subjects could perform a spatial working memory task with a 0.5, but not a 7, second delay.

P1: Dextran Curcumin Promotes Novel Object Recognition Memory in Rats after Ischemic Stroke
Ischemic stroke causes the depletion of energy and induces excitotoxicity and neuroinflammation in the brain that results from thrombotic blockage. Cerebral ischemia leads to many types of memory loss, including impairment of working, spatial and object recognition memoreis. Curcumin shows strong anti-oxidoinflammatory activities but it terapathics limited by its low solubility in water and cor...

Introduction: Uteroplacental insufficiency (UPI) causes neurodevelopmental deficits affecting the intrauterine growth restricted (IUGR) offspring. This study aimed to analyze the effects of Gallic acid (GA) on memory deficit and brain-derived neurotrophic factor (BDNF) content in entorhinal cortex of UPI rat models. Methods: In this experimental study, 40 pregnant Wistar rats were randomly div...

Background: The hippocampus, a vital center for learning and memory, is extremely vulnerable to neurological diseases.Several reports of cognitive and memory impairment have been published in patients with Multiple sclerosis (MS). The prevalence of MS is highest where environmental supply of vitamin D is low. In the present study spatial working memory and reference memory after treatment with ...
متن کاملEffect of Pentoxifylline on Ischemia- induced Brain Damage and Spatial Memory Impairment in Rat
Objective(s) The brief interruption of cerebral blood flow causes permanent brain damage and behavioral dysfunction. The hippocampus is highly vulnerable to ischemic insults, particularly the CA1 pyramidal cell layer. There is no effective pharmacological strategy for improving brain tissue damage induced by cerebral ischemia. Previous studies reported that pentoxifylline (PTX) has a neuroprot...

Introduction: Methomyl (MET) is a carbamate insecticide, used in agriculture and public health to eliminate harmful insects. Besides its advantages in agriculture, it causes neurotoxic effects. The aim of this study was to evaluate the effect of MET on Spatial Working Memory (SWM), oxidative stress parameters, and histopathological changes in the hippocampus, as well as the possible protective...

Objectives: Specificity impairment is a memory alteration that occurs in people with major depressive disorder (MDD). In this investigation, we intended to shine a light on obscure aspects of executive resource and capture and rumination frameworks to determine whether these theories are reliable in predicting underlying mechanisms for specificity impairment. Methods: In this correlational res...
