Ocular dominance plasticity reconsidered
Science, 2016Neuronal Plasticity How neuronal circuits are established and reformed during development and learning is unclear. One idea is that cortical circuits have virtually unlimited plasticity and are rebuilt routinely from random components. An alternative view is that some of these connections are more or less preformed and rigid.

PirB Restricts Ocular-Dominance Plasticity in Visual Cortex
Science, 2006Experience can alter synaptic connectivity throughout life, but the degree of plasticity present at each age is regulated by mechanisms that remain largely unknown. Here, we demonstrate that Paired-immunoglobulin–like receptor B (PirB), a major histocompatibility complex class I (MHCI) receptor, is expressed in subsets of neurons throughout the brain ...

Plasticity of ocular dominance columns in monkey striate cortex
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1977Abstract Ocular dominance columns were examined by a variety of techniques in juvenile macaque monkeys in which one eye had been removed or sutured closed soon after birth. In two monkeys the removal was done at 2 weeks and the cortex studied at 1 1/2 years. Physiological recordings showed continuous responses as an electrode advanced

The role of muscarinic acetylcholine receptors in ocular dominance plasticity
1989During a critical period of postnatal development neuronal connections in the visual cortex are susceptible to experience-dependent modifications. In normally reared kittens the majority of neurons respond to visual stimulation of either eye. A few days of monocular deprivation, however, are sufficient to render most cortical neurons unresponsive to ...

Lithium reduces ocular dominance plasticity in kitten visual cortex
Brain Research, 1991Activity-dependent processes within the visual pathway play a crucial role in the expression of ocular dominance plasticity in immature visual cortex. The necessity of non-retinal, modulatory afferents to the regulation of ocular dominance plasticity has been recognized. Among a few chemically defined signaling systems, the noradrenaline-activated beta-

Cross‐modal restoration of ocular dominance plasticity in adult mice
European Journal of Neuroscience, 2018AbstractThe temporal closure of one eye in juvenile and young adult mice induces a shift of the ocular dominance (OD) of neurons in the binocular visual cortex. However, OD plasticity typically declines with age and is completely absent in matured mice beyond postnatal day (PD) 110.

Interaction of noradrenergic and cholinergic systems in regulation of ocular dominance plasticity
Neuroscience Research, 1989We studied interactions among the noradrenergic (NA) and the muscarinic cholinergic (ACh) systems in the regulation of ocular dominance plasticity in kitten visual cortex. The cortex was bilaterally infused with 6-hydroxydopamine (6-OHDA) for a week.

Ocular Dominance Plasticity Under Metabotropic Glutamate Receptor Blockade
Science, 1996Occluding vision through one eye during a critical period in early life nearly abolishes responses to that eye in visual cortex. This phenomenon is mimicked by long-term depression of synaptic transmission in vitro, which may require metabotropic glutamate receptors (mGluRs) and is age-dependent.

Plasticity and Development of Monkey Ocular Dominance Columns
2004AbstractThis chapter presents two lengthy papers entitled “Plasticity of Ocular Dominance Columns in Monkey Striate Cortex”, and “The Development of Ocular Dominance Columns in Normal and Visually Deprived Monkeys”. The chief finding of the first paper tackles the effects of early eye removal or monocular lid closure on the ocular dominance stripes in ...
