Specialized Representations in Visual Cortex

Specialized Representations in Visual Cortex A Role for Binding?

of neurons that represent elements of a given object, and that this correlated firing labels the neuronal activity associated with one object. Different frequencies or Seeing is deceptively simple. We perceive objects, sym-phases of modulation could be used to simultaneously bols, movements, and other aspects of the visual scene label different objects. With this approach, neurons dis-without e...

Specialized vascularization of the primate visual cortex.

We have analyzed blood vessel distribution in the primary and secondary visual cortices of the squirrel monkey in relation to cortical modules, laminae, and cytoarchitectonic areas. Measurements of microvessel length in tangential sections through the primary visual cortex showed that blobs are more richly vascularized than intervening cortical regions. Thus, the mean total length of microvesse...

Stretches Neural Representations in Visual Cortex

Reconstructing representations of dynamic visual objects in early visual cortex.

As raw sensory data are partial, our visual system extensively fills in missing details, creating enriched percepts based on incomplete bottom-up information. Despite evidence for internally generated representations at early stages of cortical processing, it is not known whether these representations include missing information of dynamically transforming objects. Long-range apparent motion (A...

Primed-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...
