Miller,University of Delaware, University of California, Los Angeles.As a generally noninvasive subset of neuroscience methods, psychophysiological methods are used across a variety of disciplines in order to answer diverse questions about psychology, both mental events and behavior. Many different techniques are classified as psychophysiological. Each technique has its strengths and weaknesses, and knowing them allows researchers to decide what each offers for a particular question. Additionally, this knowledge allows research consumers to evaluate the meaning of the results in a particular experiment.  Infantolino, Z. & Miller, G. A. (2021).

Parkinson's disease is a chronic, progressive, degenerative disease of the central nervous system that produces movement disorders and changes in executive functions, working memory, visuospatial functions, and internal control of attention in affected cognitive areas. It is named after James Parkinson (1755-1824), an English neurologist who studied the disease.
