In these studies, no relationship between hormone concentrations and maternal responsiveness, as measured by attitude questionnaires, was found. For example, most women showed an increasing positive self-image during early pregnancy that dipped during the second half of pregnancy, but recovered after parturition. Separating rat pups from their mothers A) has the same effect as early handling. B) has the same effect as increased maternal grooming. C) produces increases in behavioral and endocrine stress responses in adulthood. D) both A and B E) both A and C.
Maternal aggression is under the control of a wide variety of factors that prime the females for aggression or trigger the aggressive event. Maternal attacks are triggered by the perception of sensory cues from the intruder, and here we have identified a site in the hypothalamus of lactating rats that is highly responsive to the male intruder—the ventral Cited by: Sensory processing disorder may affect one sense, like hearing, touch, or taste. Or it may affect multiple senses. And people can be over- or under-responsive to the things they have difficulties.
Butler S, Suskind MR, Schanberg SM Maternal behavior as a regulator of polyamine biosynthesis in brain and heart of the developing rat pup. Science – CAS. Our approach has been to delineate the role of sensory factors, experience, hormones, and the brain in mediating the mother’s initial responses to her young as well as the long-term maintenance of her response, after the period of hormonal priming. In addition to this rat work, we also study maternal behavior in humans. In Hamilton.

We review existing knowledge of the neural, hormonal, and sensory basis of maternal aggression in the female rat. Although females may express different kinds of aggression, such as defense or dominance, the most frequent and conspicuous form of aggressive behavior among females is the one associated with by: 5.
The sight, sound, and smell of pups are all neural stimuli to which rat mothers are responsive. This facilitates their localization of pups displaced from the nest. The hormones contribute to the onset of maternal behavior. They are responsible for maternal aggression Cited by: The specific role of progesterone in the control of maternal aggression in rats is unclear.
Under many circumstances, progesterone inhibits maternal responsiveness towards pups , , and some data indicate that it also inhibits estrogen- and testosterone-induced aggression in virgin female rats .Cited by: Sensory, hormonal, and neural control of maternal aggression in laboratory rodents Article Literature Review in Neuroscience & Biobehavioral Reviews 26(8).

Publisher Summary. This chapter discusses the progress that has been made in the study of maternal behavior in the rat with special focus on the research that has been carried out at the Institute of Animal by: Part of the Advances in Neurobiology book series (NEUROBIOL, volume 10) For mammals, sensory, social, and hormonal experience early in life is essential for the continuity of the infant’s development.
These experiences come from the mother through maternal care, and have enduring effects on the physiology and behavior of the adult by: 4. The laboratory rat – improved welfare for mothers and proved to be a good model for the study of different factors that affect the maternal behaviours, such as hormonal, sensory, neural, experiential and developmental issues.
(Whishaw and Kolb, ). Psychobiology of maternal behavior in human beings seeks to uncover the sensory, hormonal, and neural factors that regulate parental behavior in human beings with particular emphasis on mother. The expression of different behavioral components in the adult rat depends on a number of early influences, including age, hormones, manipulations of sensory cues, and perinatal undernutrition.
The rat as a model for studying maternal behavior external factors, such as hormones, reproductive experience, coordinate the maternal responsiveness of the parturient female rat.
In the rat, hormones regulate maternal behavior onset but maintenance of maternal behavior may be free from hormonal control where experienced rats don't rely on hormonal input to be maternal.
Abstract. This chapter will survey current ideas on the physiological bases of maternal behavior in the rat.
Maternal behavior is, of course, a characteristic of all mammals, and ethological descriptions of maternal care are on record for many species (Lehrman, ; Klopfer, McGeorge, & Barnett, ).Cited by: The present studies were undertaken to investigate the involvement of sensory cues in the expression of maternal behaviors and in the reinforcing properties of pups, reflected in performance on a conditioned place preference task.
Postpartum animals were either able to interact with pups in one of two novel environments or were prevented from doing so by Cited by: Abstract. Maternal behavior encompasses activities concerned with the birth, maintenance, nutrition, and protection of the young.
Although the form of these behaviors is closely related to physiological and ecological adaptations of the particular species, the variety and extent of maternal or parental care patterns in various orders of vertebrates is truly by: 1. Physiol Behav.

The instructor asked why the moth lifted its wings. One student answered that sensory receptors had fired and triggered a neuronal reflex culminating in the contraction of certain muscles. Investigating this question is a rich and growing area in sensory neuroscience.
Both extrinsic factors, such as experience with sounds, and intrinsic factors, such as the physiological state of the receiver, have been shown to produce systematic changes in sensory by: Maternal behavior in rabbits involves building a nest of straw and body hair inside an underground burrow, before parturition, and the display of a single, brief (ca.
3 min.), nursing bout per day throughout lactation. The onset and decline of digging, strawcarrying, and hair-pulling is controlled by specific combinations of estradiol, progesterone, testosterone, and prolactin (PRL).Cited by: 1.A model of sensory regulation of maternal behaviour in the female rat.
Stern () suggests that there is a complex and integrated 'dance' between rats pups and their mothers that 'choreograph' maternal behaviours. When pups are outside the nest the mother responds to distal cues - the sight, sound and smell of displaced pups.
