Abstract: Aim: Lead is a powerful metal which induced neurotoxicity through the degradation of neurons in body. Various neuronal changes have shown correlation with generation free radicals and oxidative stress. The present study was carried out to evaluate neuroprotective activity Natrium diethyl dithiocarbamate trihydrate (NDDCT) on lead neurodegeneration rat’s model. Methods: We evaluated ND...

Short-term spatial memory of rats was studied in a 12-arm radial tubular maze. Correct performance does not depend on maze structure which affects, however, thse rat's trajectory through the maze. Rats overtrained in the 12-arm radial maze show considerable transfer of the habit to a maze consisting of 12 parallel alleys entered froin a common choice area. When isolated maze channels equipped w...

This study presents a mobile application of the maze task as complementary activity for second language learning. The facilitates conducting linguistic training sessions with both pedagogical and experimental purposes. We designed Maze Task Mobile, used it in English classes native speakers Brazilian Portuguese, analyzed student perceptions through an attitude survey. Besides presenting detail,...

Nepeta L. (Lamiaceae) species are belonging to aromatic and medicinal plants. Many biological activities of have been reported. In this study, memory-enhancing nuda ssp. essential oil was aimed be evaluated in laboratory rats treated with scopolamine. GC-MS/GC-FID system used identify composition. Memory performances the were tested using Y-maze radial-arm maze. Acetylcholinesterase enzyme acti...

The striatum plays an important role in “habitual” learning and memory, and has been hypothesized to implement a reinforcement-learning algorithm in order to select actions to perform given the current sensory input. Many experimental approaches to striatal activity have made use of temporally structured tasks, which imply that the striatal representation is temporal. To test this assumption, w...

Memory deficits associated with hippocampal dysfunction are a key feature of a number of neurodegenerative and psychiatric disorders. The discrete-trial rewarded alternation T-maze task is highly sensitive to hippocampal dysfunction. Normal mice have spontaneously high levels of alternation, whereas hippocampal-lesioned mice are dramatically impaired. However, this is a hand-run task and handli...

OBJECTIVE Since the late 1980s, surgical ablation of atrial fibrillation (AF) has been one of the most effective means of curing this arrhythmia. However, about 20% of patients who underwent maze procedures have shown recurrence of AF during the follow-up periods. The aim of this study is to evaluate our result of maze procedures in last decade and to analyze the risk factors of maze failure. ...

This book aims to develop a concept of semiotic theory imagination as expressive production, which recognizes maze fictional dimensions
