Representation of a perceptual decision in developing oculomotor commands

Article Abstract:

Electrically evoked eye movements in monkeys have been used to investigate the effect of motion strength and viewing duration on oculomotor commands that develop while the monkey is viewing random dots and forming direction judgement. Eye movements evoked by electrical microstimulation of the frontal eye field during the discrimination task were determined by the monkey's subsequent direction judgement. It was found that the monkeys' behavioural performance depended on the strength and viewing duration of the motion stimulus. The close link between the deviations of evoked saccades and a decision variable inferred from behaviour suggests that developing oculomotor commands could reflect the formation of the monkey's direction judgement.

The case against a perceptual NPT

Article Abstract:

The oncoming conference of the signatories of the Nuclear Non-Proliferation Treaty should focus on the consequences of an indefinite extension of the treaty. Members should support the continuation of the treaty, but should not insist on making it perpetual as it will undermine the fight against proliferation, failing to remind nations of the hazards of proliferation.
