Gallbladder distention and the effects of several drugs on heart rate,respiratory movements and cortical potentials in cats with hypothalamic lesions

The effects of chronic hypothalamic lesions and various drugs on the viscero-visceral reflexes of cats have been investigated, utilizing measurement of the bioelectrical activity of the cerebral cortex. After coagulation of the posterolateral hypothalamus the heart rate decreased by 40–60 beats per minute, but eventually it regained its initial value. The viscero-visceral reflexes from the gallbladder to the heart were preserved after the operative procedure. Chlorpromazine and atropine blocked both arousal and the cardiorespiratory response to stimulation of the gallbladder. Similar effects were produced by novocaine and pantocaine.     

A CONTRADICTED HYPOTHESIS RELATED TO SZONDI'S THEORY: The Szondi Test as used on alcoholics

R amfalk , C. W., and R udhe , L. A contradicted hypothesis related to Szondi's theory. The Szondi Test as used on alcoholics. Scand. J. Psychol ., 1961, 2 , 100–104.—(1) The Szondi test was applied to 18 alcoholics, 18 total abstainers, and 18 'normals'. (2) According to the definition of consistency proposed in this study there is no consistent relation at the 1 per cent level of significance between any two selections of photographs made by alcoholics. (3) The results contradict theoretical claims based on Szondi's technique.     

The relative intelligibility threshold for one's own name compared with other names

Two recent experiments (Moray, 1959; Oswald, Taylor and Treisman, 1960) have shown that in dichotic listening, and in sleep one's own name seems to be responded to selectively. We have shown for 10 subjects, each listening binaurally to the same recording of a list of their names repeated at random 10 times, and masked by noise, that the subject's own name had a significantly lower threshold than other names. The effect we found was not significantly different from the one found by Oswald et al. during sleep and by Moray for the dichotic situation.

These three experiments taken together suggest that the same pattern-analysing mechanism is involved in normal listening, dichotic listening to the rejected message, and in discrimination during sleep.     

TIME RELATIONS IN DREAMS: A preliminary note

Examples are given of hypnotically induced dreams, which support the notion that series of experiences corresponding to long spans of objective time may be represented in dreams of very short duration. Both stimulus and organismic factors determine the contents of such dreams.
