Exploring Functional Mri Mapping of Human Brain Activity of Visual Cortex Organization

Abstract

Magnetic Resonance Imaging (MRI) is a powerful neuroimaging technique that has revolutionized our understanding of human brain activity. Mapping brain function in the human visual cortex using Magnetic Resonance Imaging (MRI) has provided valuable insights into the neural mechanisms underlying visual perception. Studies using MRI to examine brain activity in humans are discussed. High-speed MRI methods sensitive to shifts in cerebral blood volume (CBV), blood flow (CBF), and blood oxygenation were used to assess task-induced alterations in mental state. By applying these methods to a visual stimulus paradigm, the first functional MRI maps of human task activation were generated. The main visual cortex (Vl) of the human brain was mapped using magnetic resonance imaging, and its functional structure and frequency response were studied.
