Abstract
Facial expressions of 23 neonates were analyzed for specific features following oral stimulation with distilled water, 0.1 and 1.0 M sucrose, 0.15 and 0.25 M urea, and 0.0001 M quinine hydrochloride. Responses were videotaped and later decoded in a double-blind setting. While some features were present for all stimulations, other components were consistently associated with a specific taste quality. Within a quality, increasing the concentration elevated the incidence of features associated with that quality. Estimates of magnitude and hedonic tone conveyed by the total facial response to each stimulus suggested that the face was, within limits, an accurate reflection of stimulus quality and intensity.

The specially human attributes which distinguish the authors' species from the rest of the Mammalia have at least an intimate connection with the superior development of the central nervous system, and a peculiar interest in tracing the methods by which this complexity is of advantage to the individual.

These normative data for the intact rat can be directly compared to the taste reactivity of neurally ablated preparations which do not spontaneously feed or drink and can be utlized in determining the neural substrates necessary for the execution and regulation of ingestive behavior.
Brain ResearchThe behavioural states of the newborn infant (a review)

The concept of behavioural states in the young infant has been used in two connotations: (1) as a descriptive categorisation of behaviour; and (2) as an explanation of brain mechanisms which modify the responsiveness of the infant.

It was found, however, that a sudden increase also elicits a response, namely supercoordinated swimming, which demonstrates that chemotaxis is achieved by modulation of the incidence of tumbling both above and below its steady-state value.
Brain ResearchThe taste reactivity test. II. Mimetic responses to gustatory stimuli in chronic thalamic and chronic decerebrate rats
594 Citations1978Harvey J. Grill, Ralph Norgren
Based on the similarities in the ingestion and rejection responses of decerebrate and intact rats, it appears that discriminative responses to taste result from integrative mechanisms complete within, or caudal to, the midbrain.

This chapter shows facial expressions in the experimental part of the discussion and illustrates the three prototypes of facial play described by Darwin as that of ‘good spirit,’ of “contempt,” and of � “low spirit or disgust.”

Bacteria have a processing mechanism that compares opposing signals from the chemoreceptors for positive and negative taxis, sums these signals up, and then communicates the sum to the flagella.

This model, specific to the concentrations used, shows similarities to previous psychophysical models, especially Henning's, as well as models of stimulus relationships based on neural gustatory data.

Four experiments were concerned with the effects of brief intraoral fluid stimulation upon the nonnutritive sucking rhythm of newborn infants, finding that brief sucrose stimulation within a sucking burst tended to lengthen that burst.

Findings that male dogs find estrous urine and vaginal secretions more attractive than their nonestrous counterparts and that they prefer female urine and feces compared to corresponding samples from male dogs are partially explained.
