Braintrust: What Neuroscience Tells Us About Morality

ejop-v14i2-1589-f1Patricia Smith Churchland, professor emerita of philosophy at the University of California, San Diego, and an adjunct professor at the Salk Institute, coined “neurophilosophy,” to refer to the application of neuroscientific concepts to traditional philosophical questions. In Braintrust: What Neuroscience Tells Us about Morality, Churchland asks where values come from, and incorporates biological sciences with philosophy to answer the related moral questions.

In the first chapter, Churchland criticizes current conceptions of morality by asking why there are still unanswered fundamental questions in the field, including questions surrounding the nature of fairness. She believes that contemporary moral philosophy is “in peril of floating on a sea of mere, albeit confident, opinion” (p. 2) and has no relation to the current scientific findings in evolutionary biology and neuroscience. She suggests that we can answer some of the remaining moral questions by combining new findings in neuroscience, evolutionary biology, experimental psychology, and genetics within a philosophical framework. … Read the rest here.

Proximate mechanism of post ejaculatory refractory period after orgasm

Proximate mechanism of post-ejaculatory refractory period after orgasm and male’s need for separation from post-coital connection

The exact underlying mechanism regulating the human post-ejaculatory refractory period is not yet known. The main finding of previous research has been an occurrence of surge-like increases in plasma prolactin and oxytocin levels immediately after orgasm. However, recent advances in neuroendocrinology have resulted in the identification of a new peptide, the gonadotropin inhibitory hormone (GnIH), which is considered to inhibit the hypothalamic-pituitary-gonadal axis and sexual functions. This paper hypothesizes that GnIH causes refractoriness of the post-ejaculatory refractory period, and on the basis of studies on hormonal fluctuations at the time of orgasm, we hypothesize that in addition to its pulsatile pattern of secretion, GnIH might also exhibit a surge-like pattern of secretion.
