    Notes: Calcrete profiles (caliche) have been recognized in the Eyam Limestone from the Lower Carboniferous in the area around Monyash, Derbyshire. They occur at the top of the flank facies surrounding carbonate-mud buildups (‘knoll reefs’). Four units make up the complete profile. These are from base to top: (1) grain-supported sediment with rhizocretions, (2) matrix-supported sediment with alveolar texture, (3) pelleted calcrete, (4) laminar calcrete. Commonly one or more units are missing from the profile. Calcretes indicate subaerial exposure. The carbonate buildups of the Eyam Limestone were completely exposed soon after deposition, requiring a fall in sea-level probably in excess of 10 m. This discovery demands a review of previous regional palaeoenvironmental studies.

    Notes: Laser chemical vapor deposition of patterned iron deposits on silica glass has been carried out using an Ar ion laser-driven dissociation of iron pentacarbonyl vapor. The structure of the deposited films has been studied using optical, electron, and scanning Auger microscopic techniques. Extensive iron silicate formation is observed at the iron-glass interface and 50-μm periodic ripples are formed in the delineated deposits. The origin of the periodic structure is discussed with reference to the available analytical data and observations from related laser processing studies.

    Description / Table of Contents: Zusammenfassung 15 Gesunde und 15 ausgewählte Patienten mit mnestischer Leistungsschwäche wurden mit einer modifizierten Ratetechnik nach Shannon untersucht. Verbale transitive Inventare dienten zur informationstheoretischen Darstellung von Text-Entropie und Vergessen. Gleiche Textwörter-Mengen wurden zu bestimmten Zeiten entweder von verschiedenen Probanden nur je einmal, oder von jeweils gleichen Probanden wiederholt erraten. Gesunde organisieren das Material: hohe Informationsbeträge werden unmittelbar schwerer behalten, daher mehr wiederholt und so durch Übung besser gelernt als informationsarme Angebote. Mnestische Leistungsschwäche ist nicht nur ein Ausfall des Behaltens, sondern ein Leistungswandel des Auffassens. Dieser behindert das Lernen als Übungseffekt wiederholter Reproduktionen. Diese experimentelle Darstellung von „Organisation“ und „Leistungswandel“ präzisiert frühere gestaltpsychologische Anschauungen. Das Vergessen ist nicht einfach mit einem Verschwinden zuvor gewußter Informationsmengen gleichzusetzen. Das Entropieprofil des zu merkenden Materials bestimmt neben der Zeit und den Motivationen des Auffassens auch die mnestische Stabilität. Das Vergessen wird als eine Bedingung der Lernens, Umlernens, und Anpassens aufgefaßt.
    Notes: Summary Fifteen normal subjects (Ss) and 15 selected patients with memory deficits were examined with the aid of a modified Shannon Guessing Test. Verbal transitive inventories were used as data to serve as an information-theory model of text-entropy and forgetting. Equal numbers of text-words were guessed only once at certain times by different participants or guessed repeatedly by the same participant. Normal Ss organize the learning material in the following way: Material with a high information value is more difficult to be stored immediately; it is therefore repeated more and in the end learned better than material with low information value. Memory impairment comes about not only through a loss of retention but also through a change in the ability to perceive learning material. This change interferes with learning brought about by practising repeated reproductions. This experimental presentation of “organization” and “change of ability” defines some earlier views in “Gestalt-psychology” more precisely. The entropy profile of learning matter determines not only the time and the motivations necessary for perception, but also the stability of memory. Forgetting is thought of as a necessary condition for learning, relearning, and adaptation.

    Description / Table of Contents: Zusammenfassung Intracraniale Verkalkungen kommen bei zahlreichen Krankheiten vor. Beiderseitige idiopathische Kalkablagerungen finden sich zumeist im Globus pallidus. Zur Entdeckung intracranialer Verkalkungen ist die Computertomographie den konventionellen Röntgenaufnahmen des Schädels überlegen. Die Symptome der Patienten waren aber oft durch ganz andere Befunde begründbar. Verkalkungen in Basalganglien bilden keine nosologische Einheit und sie sind kein alleiniger Grund zu invasiven diagnostischen Maßnahmen.
    Notes: Summary Intracranial calcifications are attributed to many diseases. The globus pallidus is almost always the site of bilateral idiopathic calcium deposits. Computed tomography is superior to conventional skull radiographs in detecting intracranial calcifications. Patients had symptoms that were often explained by other findings. Basal ganglia calcification alone is not a nosological entity and does not justify invasive diagnostic procedures.

    Description / Table of Contents: Zusammenfassung Ein Mann erlitt mit 42 Jahren einen linksseitigen ischämischen Hirninsult mit vorübergehender Aphasie. Mit 49 Jahren erkrankte er durch eine rechtsseitige Infarzierung, die nun eine dauernde Unfähigkeit zum Verstehen gesprochener Sprache und zum Erkennen von Tönen oder Geräuschen hervorrief. Einfache alternative Unterscheidungen zwischen den Reizqualitäten reiner Töne konnte er noch treffen. ERA-Befunde zeigten, daß die zentralen Hörbahnen des Hirnstamms intakt waren. Diese Rindentaubheit im Gefolge bilateraler Läsionen des akustischen Cortex und angrenzender corticaler Zentren führt zu der Annahme, das auditive Erkennen sei beim Menschen beiderseits in den temporoparietalen Regionen repräsentiert.
    Notes: Summary At the age of 42 Lothar H. suffered a left-sided ischaemic brain lesion with transient aphasia, followed at the age of 49 by a right-sided ischemic infarction, which caused a continuous inability to understand spoken language and to identify tones and noises. He was still able to discriminate between single qualities of pure tones. The ERA-results showed the central acoustic pathways of the brain-stem to be intact. The occurrence of cortical deafness following bilateral lesions of the acoustic cortex and adjoining cortical centres supports the view that human auditory recognition is represented in both temporoparietal areas.
