[HTML][HTML] In vivo two-photon imaging reveals a role of arc in enhancing orientation specificity in visual cortex
Cortical representations of visual information are modified by an animal's visual experience.
To investigate the mechanisms in mice, we replaced the coding part of the neural activity …

Loss of Arc renders the visual cortex impervious to the effects of sensory experience or deprivation
A myriad of mechanisms have been suggested to account for the full richness of visual
cortical plasticity. We found that visual cortex lacking Arc is impervious to the effects of …

[HTML][HTML] Feature-selective responses in macaque visual cortex follow eye movements during natural vision
In natural vision, primates actively move their eyes several times per second via saccades. It
remains unclear whether, during this active looking, visual neurons exhibit classical …

Stream-dependent development of higher visual cortical areas
Multiple cortical areas contribute to visual processing in mice. However, the functional
organization and development of higher visual areas are unclear. Here we used intrinsic …

A specific requirement of Arc/Arg3. 1 for visual experience-induced homeostatic synaptic plasticity in mouse primary visual cortex
M Gao, K Sossa, L Song, L Errington… - Journal of …, 2010 - Soc Neuroscience
Visual experience scales down excitatory synapses in the superficial layers of visual cortex
in a process that provides an in vivo paradigm of homeostatic synaptic scaling. Experience …

Dynamics of neuronal sensitivity in visual cortex and local feature discrimination
A striking aspect of natural scenes is that image features such as line orientation are strongly
correlated at neighboring spatial locations but not at distant locations. Thus, during the …

Emergence of feature-specific connectivity in cortical microcircuits in the absence of visual experience
In primary visual cortex (V1), connectivity between layer 2/3 (L2/3) excitatory neurons
undergoes extensive reorganization after the onset of visual experience whereby neurons …

[HTML][HTML] Receptive-field modification in rat visual cortex induced by paired visual stimulation and single-cell spiking
Experience-dependent plasticity of visual cortical receptive fields (RFs) involves synaptic
modifications in the underlying neural circuits, but the site and mechanism of these …

Perceptual learning selectively refines orientation representations in early visual cortex
Although practice has long been known to improve perceptual performance, the neural
basis of this improvement in humans remains unclear. Using fMRI in conjunction with a …

[HTML][HTML] Recent visual experience shapes visual processing in rats through stimulus-specific adaptation and response enhancement
From an ecological point of view, it is generally suggested that the main goal of vision in rats
and mice is navigation and (aerial) predator evasion [1–3]. The latter requires fast and …
