As a cross cultural comparison with an earlier study done in West Bengal, behavioral observations were made in the Katmandu Valley of 36 well-nourished and 38 undernourished children, 7 to 18 months of age, and their mothers. Undernourished children showed lowered levels of exploratory activity and attachment behavior, especially distance interaction, and a heightened need for physical closeness to the mother. Moreover, among the undernourished children the level of intellectual performance and the overall time spent in play were decreased, while time spent sucking at the breast was increased. In contrast to the West Bengali study, maternal behavior showed no differences between the two nutritional groups, and the intercorrelations between maternal and child scores showed similar or parallel patterns of reciprocity for the well-nourished and the undernourished children. No sex or age differences were found. The findings were interpreted to support Levitsky and Barnes' hypothesis of "functional isolation" as a mechanism between undernutrition and environmental stimulation to produce long-term behavioral changes. In addition, hunger as a motivational state, expressed as increased sucking, may interfere with other motivational determinants that might lead to exploration and/or increased social contacts.

Twenty four-hour continuous recordings of gastric and duodenal motor activity were obtained in 12 normal subjects. A regular, cyclical variation in gastro-duodenal motility, consisting of periods of intesnse activity for 15--30 minutes alternating with periods of almost complete quiescence during the following 30--90 minutes, was noted in all subjects. All wave types previously described in short term studies were observed. Antral and duodenal activity were often linked, but there were many occasions when either occurred independently. Motor activity while the patient slept differed little from the waking pattern. There was no consistent motility pattern which could be associated with the subjects' hunger sensation. Eating was followed by a significant increase in duodenal motor activity which has not been previously described; the authors assume it to be due to endogenous gastrin release.

A three-hour operation on the maxilla of a woman with an unrecognized large left diaphragmatic defect using narcotic-supplemented nitrous oxide anaesthesia resulted in near-complete compression of her left lung. The condition remained asymptomatic until post-operative shivering increased the patient's metabolic requirements, leading to signs of air hunger. Aspiration of large amounts of gas from the stomach promptly relieved all symptoms in spite of significant residual X-ray findings. It is important to keep in mind that the early post-operative period is usually one of intense metabolic activity rather than of rest. Patients who are unlikely to cope with such demand should be identified pre-operatively and supported prophylactically by ventilatory assistance, ample supply of metabolic substrates and judicious sedation.

Eleven Aboriginal patients from the Northern Territory, in whom radiological examination of the abdomen demonstrated opaque masses of clay in the colon are described. This was due to the eating of white clay which is found only in streams, springs and billabongs of the coastal areas of the Territory. The habit does not appear to be a perversion of appetite, nor is it related to anaemia or pregnancy. The clay is eaten mainly for medicinal purposes or to allay hunger. The results are not always beneficial, since clay caused complications (including obstruction and perforation of the colon) in five of our 11 patients.

There is increasing evidence suggesting that the perceptual-cognitive experiences of people with anorexia nervosa and juvenile onset obesity may differ from those of people without eating disorders. The research related to several perceptual-cognitive dimensions is critically examined. These include body image perceptions; perception of hunger and satiety cues; perception of external cues; and certain personality variables which may be related to self-perception. The implications of these perceptual-cognitive variables for the treatment of anorexia nervosa and obesity are discussed. The relative efficacy of some behavioural and medical therapies may be related, in part, to their effects on perceptual-cognitive parameters. Recommendations are also made for investigations to further delineate the role of perceptual-cognitive difficulties in people with eating problems.

The effects of empathy, gender, and training on the ability to identify 4 infant cry-signals (birth, hunger, pain, and pleasure) were studied in 89 college students (ages 18 to 30 yr.), all of whom were low in experience as caregivers to infants. Subjects with training scored significantly higher than those without in identifying all but the pleasure cry-signal. Subjects low in empathy scored significantly better than subjects high in empathy in recognizing the birth cry-signal. Gender made no difference. Brief training may make the crucial difference in the development of this ability. Implications for parenting and infant care are discussed.

1. In anaesthetized cats, the unitary activity of seventy-eight sensory vagal neurones was recorded in nodose ganglia by means of extracellular glass microelectrodes. 2. These neurones were stimulated by perfusion of the small intestine (duodenum and first part of jejunum) with glucose or other different carbohydrates at concentrations of 1--20 g/l. (i.e. 55--1100 m-osmole/l.). 3. The neurones were slowly adapting to stimulation and their discharge frequency was always low (1--30 Hz). 4. The activity of these neurones depended on the particular carbohydrate used and on its concentration: the discharge frequency generally increased when the concentration rose. 5. The neurones were of the C type (conduction velocities: 0.8--1.4 m/sec; mean, 1.1 m/sec). 6. In contrast with the known neurones connected to the gastro-intestinal tension receptors, they were not obviously activated by intestinal contractions or distensions. 7. In the same way, the stimuli which produced the response of other known endings, i.e. the mucosal receptors, were not effective; these stimuli included in particular stroking of the mucosa, over-distension of the bowel, intestinal perfusion with alkaline or acid solutions. On the other hand, the use of substances other than glucose (KCl and NaCl of the same osmolarity) showed that the osmotic pressure was not directly related to the receptor activation. 8. Therefore it is proposed to call the endings corresponding to these neurones 'glucoreceptors'. 9. The effect of glycaemia and intestinal motility were also studied. These variables acted presumably by changing the intestinal absorption rate. 10. The functional characteristics of the glucoreceptors (in particular the short latency of their response) strongly suggested that they were located close to the intestinal epithelium. 11. An ultrastructural study was performed in an attempt to identify the histological site of the receptors. Many non-medullated fibres were observed in the villi, especially beneath the epithelial layer. They gave complex branchings with abundant swellings. Some of them, at least, belonged to the vagal sensory component, because they were less numerous after unilateral selective sensory vagotomy. Therefore these complex endings could serve as the vagal glucoreceptors. 12. The roles of vagal intestinal glucoreceptors are discussed. Their functional characteristics as well as the clinical and experimental data suggest that they may be involved in the regulation of different types of alimentary behaviour (hunger, thirst, alliesthesia) and energy balance.

Female albino rats trained to press a bar to turn off a bright light while water-satiated performed better than rats trained while thirsty. It is suggested that thirst elicits responses such as increased activity which compete with stationary behavior required for bar-pressing. Since the proposed competing responses may facilitate locomotor behavior, this hypothesis might also explain the general finding that hunger or thirst facilitates performance on tasks where escape or avoidance requires locomotion. Switching satiated subjects to the thirsty condition caused decreased performance, while the opposite shift apparently failed to improve performance above the level of a control group.

This essentially descriptive paper deals with inhibition as a symptom or as a behavior pattern and studies the different areas of; inhibition of the intellect (i.e. a decrease in though production witnessed by disorders of language flow), reduced attention span (distractability, inability to concentrate), inhibition of volition (abulia, indecisiveness), memory inhibition (in the sense of selective amnesias, post-crisis amnesias, cyclical amnesias), restriction of the basic drives (which can touch the life principle, the need for sleep, hunger, sexual drive), emotional inhibition including a feeling of inferiority and self-doubt which affects interpersonal relations: in this sense inhibition can also manifest itself in experiences of estrangement and depersonalization. A dynamic study of inhibition should first deal with the presumed relationship between the symptom and a specific pathological process and analysis of the underlying inconscious mecanisms.

The relationship of selected pretreatment characteristics to weight gain during treatment was examined in 81 anorexia nervosa patients. Good prognostic indicators correlating positively with weight gain were: no previous hospitalizations for anorexia nervosa, a great amount of overactivity before treatment, less denial of illness, less psychosexual immaturity and the admission to feeling hunger. A perinatal history of delivery complications was associated with the poor outcome predictor of prior hospitalizations.
