Kisspeptin and Seasonality of Reproduction
2013Wild and domesticated species display seasonality in reproductive function, controlled predominantly by photoperiod. Seasonal alterations in breeding status are caused by changes in the secretion of gonadotropin-releasing hormone (GnRH) that are mediated by upstream neuronal afferents that regulate the GnRH cells.

Kisspeptin and GnRH Pulse Generation
2013The reproductive neuropeptide gonadotropin-releasing hormone (GnRH) has two modes of secretion. Besides the surge mode, which induces ovulation in females, the pulse mode of GnRH release is essential to cause various reproductive events in both sexes, such as spermatogenesis, follicular development, and sex steroid synthesis.

Electrophysiology of Kisspeptin Neurons
2013Kisspeptin is an important regulator of reproduction. Electrophysiological studies show that kisspeptin neurons of the arcuate nucleus that co-localize neurokinin B and dynorphin (aka KNDy neurons) fire action potentials in a tonic, irregular, or burst firing manner. Gonadectomy dramatically alters the membrane properties of KNDY neurons from male mice

Kisspeptin: Past, Present, and Prologue
2013Research in the nineteenth and early twentieth century established that the brain awakens reproduction, governs reproductive activity in the adult of virtually all vertebrates. By 1950, nearly 100 years later, scientists realized that the hypothalamus and its neurosecretory products play a key role in regulating gonadal function in both males and ...
