The nucleus raphe pallidus receives afferent connections from the periaqueductal gray, the Paraventricular nucleus of hypothalamus, central nucleus of the amygdala, lateral hypothalamic area, and parvocellular reticular nucleus. Also, the nucleus raphe pallidus receives afferents from the medial preoptic area, median preoptic nucleus and lateral paragigantocellular reticular nuclei. WebThe nucleus raphe magnus was lesioned on eighteen separate occasions; in each case the temperature‐responsive activity of the thalamic or hypothalamic neurone was abolished. 5. Extensive brain‐stem lesions which spared only the mid‐line nucleus raphe magnus had no discernible effect on the responses of the thalamic or hypothalamic neurones to scrotal …
