    Notes: Summary To analyze the affect of blocking neuronal activity on NMDA receptor levels during development, we have injected chick embryos with the competitive NMDA receptor antagonist NPC 12626 from E17 to E19. Brains from drug-treated (n=7) and control (n=6) embryos (E20) were processed for receptor autoradiography using the NMDA competitive antagonist [3H]CGP 39653. NPC 12626 treatment caused a significant 24 to 46% increase in [3H]CGP 39653 binding in both the forebrain and cerebellar cortex. The results support the hypothesis that NMDA receptor levels are regulated by activity-dependent mechanisms.

    Description / Table of Contents: Zusammenfassung Der Zusammenhang zwischen Blickwendung und Lidschlag wurde experimentell untersucht. Als wirksame Faktoren erwiesen sich die Größe der Blickwendung, die Kopfbewegung, die Art der Wahrnehmungsobjekte (Person — Gegenstand) und bei Personen der Grad der Aufmerksamkeitszuwendung. Über alle Versuchsbedingungen hinweg zeigte sich die relative Häufigkeit des Lidschlages bei der Blickwendung als individuell konstant.
    Notes: Summary The relationship between gaze movement and eye blink was investigated. The angle of eye movement, movement of the head, the type of objects perceived (person-object) and (when persons were viewed) the degree of attention were found to be relevant factors. Under all conditions studied, the relative frequency of blinking during gaze movement was shown to be individually constant.
