    Vision scientists may be interested in a new release of Presentation,
    version 0.40. Presentation is a Windows 95/98/ME/2000 program for stimulus
    delivery and experimental control that delivers visual and auditory stimuli
    with sub-ms temporal precision that is verified for each stimulus and
    response event. Version 0.40 adds Presentation control language that
    facilitates animation, simplifies experiment development and permits
    stimuli to be modified in real-time based on behavioral responses. As a
    result, Presentation 0.40 supports a full complement of adaptive
    psychophysical procedures (e.g., two alternative forced choice, threshold
    determination, etc.). Presentation 0.40 can also use parallel and serial
    inputs for stimulus control, and can output control pulses to permit PCs to
    automate behavioral conditioning procedures. In addition, Presentation
    0.40 permits physiological responses to control stimulus delivery. For
    example, Presentation 0.40 can assist in defining neuronal receptive fields
    by changing stimuli to optimize neuronal discharge rates and can change
    stimulus position in real-time based on changes in head or eye position. A
    free version of Presentation 0.40 (expiration date: January 2002) is
    available for download at www.neurobehavioralsystems.com .
