[A case of recurrent paraneoplastic cerebellar ataxia with antibodies to GluR epsilon 2 causally related to ganglioneuroma].

Acute cerebellar ataxia (ACA) in childhood following viral infection is a self-limited disease. We present a boy with recurrent episodes of paraneoplastic cerebellar ataxia associated with a ganglioneuroma. A 20-month-old boy developed the first episode of cerebellar ataxia after nonspecific respiratory tract infections.

[Event-related potentials to response production and inhibition in go/nogo task. II. Developmental change of response inhibition].

In order to investigate the developmental changes of response inhibition in frontal function, event related potentials (ERPs) during a Go/NoGo task were collected. Twelve developmentally normal subjects, ranging in age from 7 to 15, and 9 normal adults performed a visual Go/NoGo task, which is a continuous performance test (CPT) using 5 color samples. We obtained ERPs of the Go and NoGo conditions from 13-channel EEG recordings and measured peak latency, amplitude, and topographic distribution of the NoGo N2 and NoGo P3 components.

[Event-related potentials to response production and inhibition in go/nogo task. I. Topographical characteristics to different visual stimulus sequences].

Event-related potentials (ERPs) were measured in eight healthy right-handed adults during three different visual Go/NoGo tasks, which consisted of color, figure, and Chinese character (kanji) paradigms. Subjects responded to a Go stimulus after a cue stimulus from the monitor during the execution of a continuous performance test (CPT). We obtained ERPs of the Go and NoGo conditions from 13-channel EEG recordings and measured peak latency, amplitude, and topographic distribution of each component.
