Central Organization of Chemoreceptor Input
1980It has long been known that the reflex excitatory effects of stimulating the arterial chemoreceptors are exerted mainly on the respiratory and circulatory systems (1). As yet, the mechanism by which this chemoreceptor input is transformed into an increased activity of the respiratory and sympathetic outputs has not been elucidated.

Hierarchically organized economics: input-output analysis
International Journal of Systems Science, 1985In this paper a model for the study of hierarchically organized economics is proposed. The input-output analysis method is used to describe the interactions between the economic world level, the economic national level and the level of economic sectors and also the interactions between the national level, the level of economic sectors and the level of ...

Soil Organic Carbon Input from Urban Turfgrasses
Soil Science Society of America Journal, 2010Turfgrass is a major vegetation type in the urban and suburban environment. Management practices such as species selection, irrigation, and mowing may affect C input and storage in these systems. Research was conducted to determine the rate of soil organic C (SOC) changes, soil C sequestration, and SOC decomposition of fine fescue (

Input-output organization of the rat vibrissal motor cortex
Experimental Brain Research, 1994The afferent and efferent connections of the vibrissal area of the rat motor cortex (VMCx) were investigated by injecting Phaseolus vulgaris leucoagglutinin (PHA-L) or wheat germ agglutinin-horseradish peroxidase into the physiologically defined VMCx.

Amygdaloid Nucleus: New Afferent Input from the Vomeronasal Organ
Science, 1970Terminal degeneration stained by the Fink-Heimer technique was found in the medial and cortical amygdaloid nuclei in a discrete zone after lesions were inflicted in the accessory olfactory bulb but not after lesions were made in the main olfactory bulb in the rabbit.

Neural input and neural control of the subcommissural organ
Microscopy Research and Technique, 2001The neural control of the subcommissural organ (SCO) has been partially characterized. The best known input is an important serotonergic innervation in the SCO of several mammals. In the rat, this innervation comes from raphe nuclei and appears to exert an inhibitory effect on the SCO activity.

The Young Child's Gender Schema: Environmental Input, Internal Organization
Child Development, 1989The relation among children's ability to apply gender labels, their tendency to emit sex-typed behavior, and their parents' attitudes and reactions toward sex-typed behaviors was studied. The children were observed at home with their parents when the children were 18 months old, before any of them had passed the gender-labeling task, and at 27 months ...

Neural Inputs to the Subcommissural Organ
1993Among the circumventricular organs of the vertebrates, the subcommissural organ (SCO), a specialized area of ependyma, is one of the most fascinating. Its modified ependymal cells arranged in a pseudostratified epithelium are elongated, high cylinders that contact apically the ventricular cerebrospinal fluid. The SCO ependymocytes appear as specialized

Enhancing soil vitality with organic inputs
Soil vitality is essential for sustainable agriculture and soil organic carbon (SOC) as a key indicator of soil health. SOC influences microbial diversity and nutrient cycling, which is critical for maintaining soil productivity. Organic inputs like compost, manure, and plant residues improve the physical, chemical, and biological properties of soil ...Mahapatra, Subham, Mahapatra, Subham
