Cooperative filtering and transmission of visual information
We applied information-theoretic methods to multi-electrode array recordings in the primary visual cortex of cats to quantify the cooperation and temporal structure that arise in the responses of neural populations to drifting sinusoid gratings. The temporal structure and joint firing in these responses contributed information useful for discriminating small (<10o) orientation differences. The ...
متن کاملChapter 1 Adaptive Information Filtering
A financial analyst wants to be alerted of any information that may affect the price of the stock he is tracking; an agent working in the Homeland Security Department wants to be alerted of any information related to potential terror attacks; a customer call center representative wants to answer customer calls about problems that he can handle; and a student wants to be alerted of fellowship or...
متن کاملTonic inhibition enhances fidelity of sensory information transmission in the cerebellar cortex.
Tonic inhibition is a key regulator of neuronal excitability and network function in the brain, but its role in sensory information processing remains poorly understood. The cerebellum is a favorable model system for addressing this question as granule cells, which form the input layer of the cerebellar cortex, permit high-resolution patch-clamp recordings in vivo, and are the only neurons in t...
متن کاملPrimed-burst potentiation in adult rat visual cortex in vitro
The effectiveness of θ pattern primed-bursts (PBs) on development of primed-burst (PB) potentiation was investigated in layer II/III of the adult rat visual cortex in vitro. Experiments were carried out in the visual cortical slices. Population excitatory post-synaptic potentials (pEPSPs) were evoked in layer II/III by stimulation of either white mater or layer IV. To induce long-term potenti...
متن کاملAdaptive shape processing in primary visual cortex.
The ability to derive meaning from complex sensory input requires the integration of information over space and time, as well as cognitive mechanisms to shape that integration. We studied these processes in the primary visual cortex (V1), where neurons are thought to integrate visual inputs along contours defined by an association field (AF). We recorded extracellularly from single cells in mac...
