“…More generally, the array of arousal-related phenomena that is modulated by estrogens provides indirect evidence of the importance of estrogens to elementary arousal. In women, fMRI analysis has shown that the menstrual cycle modulates arousal circuitry (Goldstein, et al, 2005), and affects cognition (Resnick, et al, 1998;Swerdlow, et al, 1997), ingestive behavior (Fricke, et al, 2006), and sexual arousal (Diamond, et al, 1972;Stanislaw and Rice, 1988). These are supported by a growing body of studies in research animals regarding mood (i.e.…”

(1) During the light, all treatments reduced voluntary activity. (2) In the dark, estrogens increased, while estrogens in combination with restricted diet decreased, horizontal activity. (3) In the dark, restricted diet alone had little effect on voluntary activity, but reduced it when combined with estrogen treatment. (4) All treatments reduced responses to the olfactory stimulus. The dependence of results on time of day was unexpected. Further, different patterns of results for the three treatments suggest that estrogens and food restriction did not have equivalent or additive effects on arousal. While contrary to the main prediction, these findings are discussed in terms of the animals' adaptive preparations for reproduction [Schneider, J.E., 2006. Metabolic and hormonal control of the desire for food and sex: implications for obesity and eating disorders. Horm. Behav. 50, 562-571].

“…Most of the literature reviewed for this article provides a fairly closed and integrated model of regulation in which the biological system analysed (in rats or humans) and itsfor the most part labenvironment are presented as ontologically distinct. Nevertheless, in their analysis of the cybernetics of body weight regulation, Fricke et al (2006) examine the role of systems thinking in analysing the molecular aspects of homoeostatic control of food intake. Their conclusion is worth citing at length for it marks a clear break with the tenor of much of the literature on homoeostatic regulation:…”

This article examines the way the category of 'the sensorial' is mobilised across obesity research and care practices for overweight persons in France. The 'natural' body is understood to have developed mechanisms that motivate eaters to seek out energy-dense foods, a hardwiring that is maladaptive in today's plethoric food environment. The article analyses the feedback models mobilised in scientific literature on the neuroendocrine processes regulating appetite. The analysis of how 'the sensorial' is studied and used to treat patients provides a vantage point onto the ways foods and bodies transform each other. Recent findings show that fat cells influence metabolism by secreting hormones, revealing that eaters are affected by the materiality of the foods they ingest. 'The sensorial' functions as a regulator in the feedback mechanisms where social norms regulating foodscapes become enfolded in the molecular processes that control appetite regulation. The article traces the work that the category of 'the sensorial' does as it flows through the loops and feedbacks between scientific evidence, policy and care. It examines the way pleasure and the sensations of eaters are increasingly foregrounded in French nutritional health promotion strategies in a context where informing eaters is increasingly deemed ineffective.

The attribution of control elements to biological structures always contains the problem of semantic simplification, because the biological structure is reduced to a singular meaning.
