Abstract Background and Objective: Alzheimer’s disease (AD) is a weakening neurodegenerative disorder typified by increased b-amyloid (Ab) deposition and neuronal dysfunction causing to impaired learning and memory. Among proposed risk factors, induced oxidative stress is a main cause for incidence of the disease. The aim of this study was to determine the effects of the rosmarinic acid on lear...

background and objective: alzheimer’s disease (ad) is a neurodegenerative disorder specified by deposition of b-amyloid (ab) and neuronal loss that leads to learning and memory disturbances. one of the most important causes of ad is glutamate-dependent excitotoxicity in brain regions that is vulnerable to ad. according to previous reported results, it was revealed that riluzole, as a glutamate ...

introduction: aphasia is a language disorder resulting from a lesion in the cerebral cortex. in this case report, we present a polyglot patient who recovered from aphasia by speaking his newly active learned language case report: a 69 years old male referred with acute onset right hemiparesis and global aphasia. after imaging, he treated with 75 mg r-tpa (0.9 mg/kg). after the fourth day of hos...

Computational models of reinforcement learning have helped dissect discrete components of reward-related function and characterize neurocognitive deficits in psychiatric illnesses. Stimulus novelty biases decision-making, even when unrelated to choice outcome, acting as if possessing intrinsic reward value to guide decisions toward uncertain options. Heightened novelty seeking is characteristic...

Associative learning plays an important role in the development of anxiety disorders, but a thorough understanding of the variables that impact such learning is still lacking. We investigated whether individual differences in autobiographical memory specificity are related to discrimination learning and generalization. In an associative learning task, participants learned the association betwee...

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder primarily characterized by deficits in social interaction, communication and implicit skill learning. OBJECTIVE To analyse the results of research on "motor learning" and the means used for measuring "autistic disorder". METHODS A systematic literature search was done using Medline/PubMed, Web of Science, BVS (virtual health li...

stuttering as a disorder from which many people suffer has drawn the attention of many psychologists and theorists. however, very few studies have investigated the incidence of this phenomenon in second language learning. this study deals with the problem from only one perspective: how does stuttering in second language of a stammerer come to exist? the answer to this question seems to be vague...
