Title: | Plasticity in the human visual cortex: an ophthalmology-based perspective | Authors: | Rosa, Andreia Martins Silva, Maria Fátima Ferreira, Sónia Murta, Joaquim Castelo-Branco, Miguel |
Issue Date: | 2013 | Publisher: | Hindawi | Serial title, monograph or event: | BioMed Research International | Volume: | 2013 | Abstract: | Neuroplasticity refers to the ability of the brain to reorganize the function and structure of its connections in response to changes in the environment. Adult human visual cortex shows several manifestations of plasticity, such as perceptual learning and adaptation, working under the top-down influence of attention. Plasticity results from the interplay of several mechanisms, including the GABAergic system, epigenetic factors, mitochondrial activity, and structural remodeling of synaptic connectivity. There is also a downside of plasticity, that is, maladaptive plasticity, in which there are behavioral losses resulting from plasticity changes in the human brain. Understanding plasticity mechanisms could have major implications in the diagnosis and treatment of ocular diseases, such as retinal disorders, cataract and refractive surgery, amblyopia, and in the evaluation of surgical materials and techniques. Furthermore, eliciting plasticity could open new perspectives in the development of strategies that trigger plasticity for better medical and surgical outcomes. | URI: | https://hdl.handle.net/10316/109708 | ISSN: | 2314-6133 2314-6141 |
