Detecting Diffusion Imaging constructive connectivity analysis for “What” stream Visual Pathways with correlations to Visual Agnosia

Visual perception is the ability to interpret the surrounding environment. A hypothetical “ventral” stream visual pathway explains how we perceive objects with respect to spatial orientation. The ventral stream fibers extend between “Visual cortex to Inferior temporal gyrus. The previous studies have failed to prove any indications on the -structural connectivity of this pathway. This study is designed to trace the existence of neural structural connectivity between “Visual cortex with Inferior temporal gyrus” using “Diffusion Tensor Imaging Tractography”, which aims to correlate its functional importance with visual object perception. The observational analysis used thirty-two healthy adults, ultra-high b-value and diffusion MRI datasets from an Open access research platform. The datasets range from both sexes, between 20–49 years, with mean age of 30.4 years. The confirmatory observational analysis process includes; datasets acquisition, pre-processing, processing, reconstruction, fiber tractography and analysis using software tools. All the datasets confirmed the fibre structural extension between, “Visual cortex to Inferior temporal gyrus in both the sexes may responsible for the visual perception of objects. This new fiber connectivity evidence justifies the structural relevance of visual perception impairments, such as visual object agnosia.
