Semantic retrieval, mnemonic control, and prefrontal cortex.
Accessing stored knowledge is a fundamental function of the cognitive and neural architectures of memory. Here, the authors review evidence from cognitive-behavioral paradigms, neuropsychological studies of patients with focal neural insult, and functional brain imaging concerning the mechanisms underlying retrieval of semantic knowledge and their association with prefrontal cortex. First, the ...
متن کاملOrganization of mnemonic and response operations within prefrontal cortex.
There is mounting evidence that prefrontal cortex (PFC) is activated during mnemonic operations such as working memory maintenance and also during response-related operations. In the current study, we examine the neural organization of mnemonic and response operations with respect to each other within PFC. Stimulus-evoked and sustained functional MRI activity was recorded during performance of ...
متن کاملConsolidation of learning strategies during spatial working memory task requires protein synthesis in the prefrontal cortex.
Working memory is a temporary memory store where information is held briefly until the appropriate behavior is produced. However, the improvement in the performance of working memory tasks with practice over days points to the existence of a long-lasting component associated with learning strategies that lead to optimal performance. Here we show that the improvement in the performance of mice i...
متن کاملthe effects of time planning and task complexity on accuracy of narrative task performance
هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...
Task learning reveals signatures of sample-based internal models in rodent prefrontal cortex
9 The idea that brains use probabilistic internal models of the world is a powerful 10 explanation for a range of behavioural phenomena. Unclear is whether or how neu11 rons represent such models in higher cortical regions, learn them, and use them in 12 behaviour. To address these issues, we sought evidence for the learning of internal 13 models by cortical neurons during a behavioural task. U...
