    Notes: Summary A technique is described which enables the determination of local blood flow in different points of the carotid body. The blood flow measured in the middle zone of the catorid body at mean blood pressure of 120 to 130 mm Hg was about 2000 ml/100 gxmin and corresponded to the total flow values known thus far. It was found that the flow/g weight decreases from the arterial inflow towards the periphery. Under our experimental conditions no signs of autoregulation could be detected. Under special experimental conditions differnnt flow distributions were observed in the carotid body.

    Description / Table of Contents: Zusammenfassung Neuropsychologische Befunde im Verlauf corticaler Blindheiten bei Gefäßverschlüssen der Aa. cerebri posteriores oder nach Spasmen im Anschluß an Subarachnoidalblutungen und angiographische Untersuchungen werden bei 4 rechtshändigen Patienten (2 Frauen, 2 Männer) im Alter von 53 bis 70 Jahren dargestellt. Bei einer Kranken persistierte die totale Blindheit 3 Monate bis zum Tode und dauerte bei einem Kranken 4 Wochen und bei 2 Patienten 1–2 Tage lang an. Verwirrtheitszustände und optische Halluzinationen fanden sich bei 3 Kranken. Die Nichtbeachtung der eigenen Blindheit (Anton-Syndrom) war am deutlichsten bei einer Kranken mit arteriographisch gesichertem beidseitigen A. cerebri posterior-Verschluß und bei den anderen Fällen geringer ausgeprägt. Während der Rückbildung bestanden Anzeichen einer vorwiegend rechtshemisphärischen Läsion mit Hemianopsie nach links und Minderung des optokinetischen Nystagmus nach links und Prosopagnosie. Dysmorphopsien mit veränderter Physiognomiewahrnehmung fanden sich bei einer Kranken. Vorübergehende Farberkennungsstörungen bestanden bei 3 Kranken. Die Beobachtungen werden im Zusammenhang mit Befunden der Literatur diskutiert.
    Notes: Summary Neuropsychologic findings during recovery from cortical blindness are described in four right-handed patients (two female, two male) aged 53 to 70 years. The lesions were due to occlusion of both posterior cerebral arteries (Case 1) and vascular spasm following subarachnoidal hemorrhage (Case 3) or angiography (Cases 2 and 4). Complete blindness lasted for 3 months until death in Case 1, 4 weeks in case 2, and 1 to 2 days in Cases 3 and 4. Confusional states and visual hallucinations were pronouced in three cases. Anosognosia (Anton's syndrome) was most pronounced in a patient with occlusion of both posterior cerebral arteries and less obvious in the remaining patients. During the recovery phase, symptoms of right hemisphere involvement were prominent with left-sided hemianopsia and diminished optokinetic nystagmus to the left, prosopagnosia in two cases, and dysmorphopsia with altered physiognomic recognition in one case. Transient disturbances of color recognition occurred in three patients. The observations are discussed with reference to clinical and neuropathologic findings of the literature.
