Frontiers in Neural CircuitsThe existence of cortical columns, regarded as computational units underlying both lower and higher-order information processing, has long been associated with highly evolved brains, and previous studies suggested their absence in rodents.

Using psychophysical performance to predict short-term ocular dominance plasticity in human adults. [PDF]
J Vis, 2020 Binocular rivalry has become an important index of visual performance, both to measure ocular dominance or its plasticity, and to index bistable perception.

All-or-none disconnection of pyramidal inputs onto parvalbumin-positive interneurons gates ocular dominance plasticity. [PDF]
Proc Natl Acad Sci U S A, 2021 Disinhibition is an obligatory initial step in the remodeling of cortical circuits by sensory experience. Our investigation on disinhibitory mechanisms in the classical model of ocular dominance plasticity uncovered an unexpected form of experience ...

Short-term plasticity in the human visual thalamus
eLife, 2022 While there is evidence that the visual cortex retains a potential for plasticity in adulthood, less is known about the subcortical stages of visual processing.

Distinctive Features of Adult Ocular Dominance Plasticity [PDF]
The Journal of Neuroscience, 2008 Sensory experience profoundly shapes neural circuitry of juvenile brain. Although the visual cortex of adult rodents retains a capacity for plasticity in response to monocular visual deprivation, the nature of this plasticity and the neural circuit changes that accompany it remain enigmatic.

Ocular dominance plasticity disrupts binocular inhibition-excitation matching in visual cortex. [PDF]
Curr Biol, 2015 SummaryBackgroundTo ensure that neuronal networks function in a stable fashion, neurons receive balanced inhibitory and excitatory inputs. In various brain regions, this balance has been found to change temporarily during plasticity.

Frontiers in Aging Neuroscience, 2016 The primary visual cortex is widely used to study brain plasticity, which is not only crucial for normal brain function, such as learning and memory, but also for recovery after brain injuries such as stroke.

Homeostatic plasticity mechanisms are required for juvenile, but not adult, ocular dominance plasticity [PDF]
Proceedings of the National Academy of Sciences, 2012 Ocular dominance (OD) plasticity in the visual cortex is a classic model system for understanding developmental plasticity, but the visual cortex also shows plasticity in adulthood. Whether the plasticity mechanisms are similar or different at the two ages is not clear.

The sedating antidepressant trazodone impairs sleep-dependent cortical plasticity.
PLoS ONE, 2009 BackgroundRecent findings indicate that certain classes of hypnotics that target GABA(A) receptors impair sleep-dependent brain plasticity. However, the effects of hypnotics acting at monoamine receptors (e.g., the antidepressant trazodone) on this ...
