The anterior pituitary of teleost fish contains a variety of endocrine cells, which, under control from the hypothalamus, release trophic hormones and thereby play a major role in reproduction, social behavior, and growth. In fish, hypothalamic fibers directly innervate the pituitary. The hypothalamic hormones released from these fibers bind to membrane(More)
Organotypic cultures, prepared from hypothalamo-pituitary slices of tilapia, were developed to enable long-term study of secretory cells in the pituitary of a teleost. Values of membrane potential at rest were similar to those recorded from acute slices, and cells presented similar spontaneous spikes and spikelets. Some cells also exhibited slow spontaneous(More)
Although spontaneous luteinizing hormone (LH) surges are preventable with gonadotropin releasing hormone agonist (GnRH-a) inclusion in ovarian stimulation protocols, GnRH-a-containing protocols are more expensive and associated with an increased risk of ovarian hyper-stimulation syndrome. The present study assessed whether spontaneous LH surges occur in(More)
