    Description / Table of Contents: Zusammenfassung 1. Die Angaben Heidels sind nicht zu bestätigen. 2. Die Typenbestimmbarkeit der SEP steht in Abhängigkeit von der Trocknungszeit der Blutspuren, der Menge des vorzulegenden Untersuchungsmaterials, dem Spurenträger. 3. Die Variablen wurden dargestellt, die Ergebnisse tabellarisch festgehalten. 4. Wir machten die Erfahrung, daßSpuren, die nach Asservierung sofort in die Kältetruhe (−40°C) gebracht werden, längere Zeift verwertbare Resultate erzielen lassen. Spuren, die bereits den größten Teil ihrer Aktivität bei Zimmertemperatur verloren hatten, können durch die Kälte nicht reaktiviert werden. Wenn Blutspuren jedoch längstens bis 8 Std bei 20–24° C getrocknet, sofort asserviert und unmittelbar, z.B. am Wochenende, in −40° C überführt werden, dürfte am Montag ein Ergebnis noch zu erzielen sein. Radam und Strauch (1966) werden insoweit bestätigt, als die Aktivitätshaltbarkeit des Enzyms in tiefer Temperatur größer ist.
    Notes: Summary The limits of the SEP identification in the blood spots under various circumstances i.e. the dependence on blood quantity, temperature, and carrier have been studied. Heidel's statement that she has been able to identify the SEP in 30 days old spots could not be confirmed. In our own experiments we have been able to identify the SEP in 32 hours old blood stains using 20 mg of dry blood substance. The deep temperature (−40°C) gives better results and from criminalistics point of view we recommend the preservation of the specimens under such conditions.

    Notes: Summary Effects of monocular and binocular stimulations upon cells of the superficial layer (superficial grey and optic strata) of the superior colliculus (SC) were studied in chronic cats with painless head fixation. They responded vigorously to moving stimuli (a 2° wide black stripe or a light slit of the same width, both moving at 40–100°/sec). Most cells were directionally selective and binocularly driven usually with a contralateral ocular dominance. In a sample of 71 cells the five types of binocular interaction were found. In 36 units (50.7%) the response to binocular stimulation was larger than the sum of the responses to monocular stimulation of both eyes (facilitation) and in 12 units (16.7%) the reverse was true (occlusion). In 7 units (9.9%) the binocular response was equal to the sum of the two monocular responses (summation). In 11 units (15.5%) the binocular response was smaller than the response to dominant eye stimulation (inhibition). In 5 units (7.0%) whose background discharges were suppressed by monocular stimulation of one eye or both suppression became less marked for binocular stimulation (disinhibition). The most common type of binocular interaction was facilitation in the units with a clear ocular dominance and it was summation or occlusion in the units lacking ocular dominance. Facilitatory and inhibitory binocular interactions were more frequently seen in the directionally selective units than in the directionally non-selective ones
