Prominent gamma band activity during visual motion perception in early-stage Alzheimer's disease.

ABSTRACT:

Introduction

Alzheimer's disease (AD) affects multiple neural pathways and regions, resulting in various visual impairments such as motion perception. Generally, gamma-band activities during visual motion perception have been thought to reflect ongoing cognitive processes. Nevertheless, few studies have specifically examined induced gamma band activity during visual motion perception in AD patients. Therefore, after performing magnetoencephalography (MEG) recording during apparent motion (AM) stimulation for the left hemi-visual field in patients diagnosed as having AD in the early stage, we compared the results with findings of cognitive performance.

Methods

Seventeen AD patients in the early stage and 17 controls matched for age, sex, and educational attainment participate
