Neural mechanisms of short-term plasticity in the human visual system.
Following circumscribed retinal damage, extensive reorganization of topographically organized visual cortical areas has been demonstrated in several species of mammals (including humans). Although reorganization is often studied over extended time scales, neural response properties change within seconds of retinal deafferentation. Understanding the mechanisms underlying these short-term effects...
متن کاملNeural Mechanisms of Short-term Visual Plasticity and Cortical Disinhibition
iii ACKNOWLEDGEMENTS I wish to thank my advisor, Paul Corballis, for his guidance, patience, and friendship all these years. Without his mentorship I could never have made it this far. I would also like to thank my dissertation committee members Parks have always been a major source of inspiration and support. I cannot thank them enough. Most of all, I must express an incredible degree gratitud...
متن کاملNeural mechanisms of information storage in visual short-term memory.
The capacity to briefly memorize fleeting sensory information supports visual search and behavioral interactions with relevant stimuli in the environment. Traditionally, studies investigating the neural basis of visual short term memory (STM) have focused on the role of prefrontal cortex (PFC) in exerting executive control over what information is stored and how it is adaptively used to guide b...
متن کاملthe effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
15 صفحه اولShort-term synaptic plasticity in the visual cortex during development.
The maturation of short-term synaptic plasticity was studied in slices of the visual cortex obtained from rats during the first 47 days of postnatal life. Responses of cortical neurons to repetitive stimulation of the white matter at frequencies >5 Hz were examined by recording intracellularly at the resting membrane potential level. Paired-pulse facilitation, an increase in the excitatory intr...
