Cortical Feedback Regulates Feedforward Retinogeniculate Refinement
According to the prevailing view of neural development, sensory pathways develop sequentially in a feedforward manner, whereby each local microcircuit refines and stabilizes before directing the wiring of its downstream target. In the visual system, retinal circuits are thought to mature first and direct refinement in the thalamus, after which cortical circuits refine with experience-dependent ...
متن کاملThe Down syndrome critical region regulates retinogeniculate refinement.
Down syndrome (DS) is a developmental disorder caused by a third chromosome 21 in humans (Trisomy 21), leading to neurological deficits and cognitive impairment. Studies in mouse models of DS suggest that cognitive deficits in the adult are associated with deficits in synaptic learning and memory mechanisms, but it is unclear whether alterations in the early wiring and refinement of neuronal ci...
متن کاملRefinement of the retinogeniculate pathway.
Much of our present understanding about the mechanisms contributing to the activity-dependent refinement of sensory connections comes from experiments done in the retinogeniculate pathway. In recent years the mouse has emerged as a model system of study. This review outlines the major changes in connectivity that occur in this species and a potential mechanism that can account for such remodell...
متن کاملRefinement of the Retinogeniculate Synapse by Bouton Clustering
Mammalian sensory circuits become refined over development in an activity-dependent manner. Retinal ganglion cell (RGC) axons from each eye first map to their target in the geniculate and then segregate into eye-specific layers by the removal and addition of axon branches. Once segregation is complete, robust functional remodeling continues as the number of afferent inputs to each geniculate ne...
متن کاملCortical feedback signals generalise across different spatial frequencies of feedforward inputs
Visual processing in cortex relies on feedback projections contextualising feedforward information flow. Primary visual cortex (V1) has small receptive fields and processes feedforward information at a fine-grained spatial scale, whereas higher visual areas have larger, spatially invariant receptive fields. Therefore, feedback could provide coarse information about the global scene structure or...
