Brain Electrical Activity Mapping: Applications to Vocal Motor Control Disorders

Brain Electrical Activity Mapping (BEAM) is a recently developed analytic tool for examining both electroencephalographic (EEG) and evoked potential (EP) data. Specifically BEAM overcomes several of the limitations which have hampered full use of these approaches, especially as applied to disorders of speech motor control. This chapter discusses rationale for development of BEAM, briefly describes the technology, and presents findings from initial studies of patients with two vocal motor control disorders — spasmodic dysphonia (SD) and stuttering (ST).
