Specificity and timescales of cortical adaptation as inferences about natural movie statistics
Adaptation is a phenomenological umbrella term under which a variety of temporal contextual effects are grouped. Previous models have shown that some aspects of visual adaptation reflect optimal processing of dynamic visual inputs, suggesting that adaptation should be tuned to the properties of natural visual inputs. However, the link between natural dynamic inputs and adaptation is poorly unde...
متن کاملCortical state and natural movie responses in cat visual cortex
20 How does cortical state affect neural responses to naturalistic stimuli, and is it analogous be21 tween anesthetized and awake animals? We recorded spikes and local field potential (LFP) 22 from all layers of isoflurane-anesthetized cat primary visual cortex (V1) while repeatedly pre23 senting wide-field natural scene movie clips. Spiking responses of single units were remarkably 24 precise,...
متن کاملLiterature as History in Twelve Years a Slave and its Movie Adaptation
This paper tries to examine literature as history, with an emphasis on the crucial role of fiction in narrating the marginalized events of history. Some fictions are actual accounts of events in history, and some are reflection of events. Actually, literature and history are integrated to each other, in a way that, pure history which shows us the reality and truth is just a myth. The pens writi...
متن کاملNatural Image Statistics and Divisive Normalization: Modeling Nonlinearities and Adaptation in Cortical Neurons
Understanding the functional role of neurons and neural systems is a primary goal of systems neuroscience. A longstanding hypothesis states that sensory systems are matched to the statistical properties of the signals to which they are exposed [e.g., 4, 6]. In particular, Barlow has proposed that the role of early sensory systems is to remove redundancy in the sensory input, resulting in a set ...
متن کاملasymptotic property of order statistics and sample quntile
چکیده: فرض کنید که تابعی از اپسیلون یک مجموع نامتناهی از احتمالات موزون مربوط به مجموع های جزئی براساس یک دنباله از متغیرهای تصادفی مستقل و همتوزیع باشد، و همچنین فرض کنید توابعی مانند g و h وجود دارند که هرگاه امید ریاضی توان دوم x متناهی و امیدریاضی x صفر باشد، در این صورت می توان حد حاصلضرب این توابع را بصورت تابعی از امید ریاضی توان دوم x نوشت. حالت عکس نیز برقرار است. همچنین ما با استفاده...
