Early Visual Deprivation Impairs Functional Development of the Visual Ventral Stream.

ABSTRACT:

Purpose

To probe the dynamic alternations of neural networks in real-time visual processing after visual deprivation (VD) removal.

Methods

A prospective cross-sectional study was conducted. Twenty children with a history of early binocular VD caused by congenital cataracts and 20 matched typically developing (TD) children were enrolled. The event-related potential (ERP) data were obtained via high-density electroencephalography. ERP data were analyzed based on three components (P1, N170, and P2), three test conditions (objects, human faces, and Chinese characters), and peak time and region of interest (ROI) chosen on a grand average head map collapsed from the averaged waveform of each group. Source localization and alpha power spectrum density were applied to define the fun
