Five key factors determining pairwise 1 correlations in visual cortex
16 The responses of cortical neurons to repeated presentation of a stimulus are highly variable, yet 17 correlated. These “noise correlations” reflect a low-dimensional structure of population dynamics. 18 Here, we examine noise correlations in 22,705 pairs of neurons in primary visual cortex (V1) of 19 anesthetized cats, during ongoing activity and in response to artificial and natural visual ...

The responses of cortical neurons to repeated presentation of a stimulus are highly variable, yet correlated. These "noise correlations" reflect a low-dimensional structure of population dynamics.

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 کاملEffects of visual deprivation on synaptic plasticity of visual cortex
TBS (Theta Burst Stimulation) and PBs (Primed Bursts) are among effective tetanic stimulations for induction of LTP in hippocampus. Recent studies have indicated that TBS is effective in LTP induction in layer III synapses of neocortex, only if applied to layer IV. However, the possibility of neocortical LTP induction using PBs, has not yet been investigated. Sensory deprivation greatly influ...
متن کاملCortical state determines global variability and correlations in visual cortex.
The response of neurons in sensory cortex to repeated stimulus presentations is highly variable. To investigate the nature of this variability, we compared the spike activity of neurons in the primary visual cortex (V1) of cats with that of their afferents from lateral geniculate nucleus (LGN), in response to similar stimuli. We found variability to be much higher in V1 than in LGN. To investig...
