“…Evidence for this stems from findings implicating auditory cues acting via midbrain and thalamic auditory regions on the GnRH system in female ring doves [33, 34]. Here the female.s own coo has been shown to regulate the GnRH1 system and acts to facilitate copulatory behavior in a ‘self-stimulation’ manner [36, 37]. …”

Gonadotropin-releasing hormone 1 (GnRH1) is a key regulator of the reproductive neuroendocrine system in vertebrates. Recent developments have suggested that GnRH1 neurons exhibit far greater plasticity at the cellular and molecular levels than previously thought. Furthermore, there is growing evidence that sub-populations of GnRH1 neurons in the preoptic area are highly responsive to specific environmental and hormonal conditions. In this paper we discuss findings that reveal large variation in GnRH1 mRNA and protein expression that are regulated by social cues, photoperiod, and hormonal feedback. We draw upon studies using histochemistry and immediate early genes (e.g., c-FOS/ZENK) to illustrate that specific groups of GnRH1 neurons are topographically organized. Based on data from diverse vertebrate species, we suggest that GnRH1 expression within individuals is temporally dynamic and this plasticity may be evolutionarily conserved. We suggest that the plasticity observed in other neuropeptide systems (i.e. kisspeptin) may have evolved in a similar manner.

“…For example, follicular development in ring doves (Streptopelia risoria) is enhanced by the presence of a courting male and by self-stimulation through nest cooing behaviour (Friedman 1977;Silver and Barbiere 1977;Cheng et al 1988). As well, ovarian recrudescence is facilitated by courtship behaviour in lizards, including the parthenogenetic species Cnemidophorus uniparens (Crews et al 1986).…”

The objective of this study was to determine the effect of early song learning on physiological and behavioural responses to song in adulthood in female mountain white-crowned sparrows (Zonotrichia leucophrys oriantha). Juvenile females were captured before they had dispersed from their natal region. In experiment 1, natal-dialect song, foreign-dialect song, and heterospecific song were played back to the birds during photostimulation when they were 1 year old and physiological responses were measured. The physiological responses (luteinizing hormone and ovarian growth) did not indicate that natal-dialect song was more stimulating than foreign-dialect song. In experiment 2, behavioural responses (solicitation displays) to the same songs were measured when the birds were 2 years old. The birds showed a clear preference for natal-dialect song, exhibiting more displays to natal-dialect song than to foreign-dialect or heterospecific song. This effect was attenuated in birds that had heard heterospecific or foreign-dialect song when they were 1 year old. These results indicate a dissociation between behavioural preferences and longer-term physiological responses to song. Although there was a behavioural preference for natal-dialect song, this did not translate into enhanced physiological response as measured here. Moreover, natal dialect song preferences may be attenuated by adult experience.Résumé : Nous avons tenté de déterminer l'effet de l'apprentissage initial du chant sur les réponses physiologiques et comportementales au chant à l'âge adulte chez des femelles du Bruant à couronne blanche (Zonotrichia leucophrys oriantha). Des femelles juvéniles ont été capturées juste avant qu'elles ne quittent leur région natale. Dans la première expérience, nous avons fait entendre aux oiseaux âgés de 1 an, au cours de la photostimulation, des chants en dialecte natal, des chants en dialecte étranger et des chants d'oiseaux d'autres espèces et nous avons mesuré leurs réponses physiologiques. Les réactions physiologiques (hormone lutéinisante et croissance ovarienne) n'ont pas permis de conclure que les chants en dialecte natal sont plus stimulants que les chants en dialecte étranger. Dans la seconde expé-rience, les réactions comportementales (sollicitation) aux mêmes chants ont été mesurées chez des oiseaux de 2 ans. Ces oiseaux ont manifesté une préférence marquée pour les chants en dialecte natal, réagissant plus à l'audition de ces chants qu'aux chants en dialecte étranger ou aux chants d'autres espèces. Cet effet était atténué chez les oiseaux exposés au dialecte étranger et aux chants hétérospécifiques à l'âge de 1 an. Ces résultats indiquent une dissociation entre les préférences comportementales et les réactions physiologiques à plus long terme à l'audition de chants. La préfé-rence comportementale pour le dialecte natal ne se traduit pas par une réaction physiologique plus forte, comme nous avons observé. De plus, la préférence pour le chant natal peut être atténuée à l'âge adulte par l'expérience préalable.[Traduit ...

“…It was shown that, in ring doves, neurons in the preoptic area and anterior hypothalamus selectively respond (single unit recordings) to the playback of male and even more of female nest coos while increases in plasma luteinizing hormone concentrations are observed in parallel [44]. These responses might represent the physiological bases of the ovarian growth induced in female doves by their production of nest coos in response to the coos of the male, the now well documented self–stimulation of ovarian development [45, 46]. …”

In canaries, specific phrases of male song (sexy songs, SS) that are difficult to produce are especially attractive for females. Females exposed to SS produce more copulation displays and deposit more testosterone into their eggs than females exposed to non-sexy songs (NS). Increased expression of the immediate early genes c-Fos or zenk (a.k.a. egr-1) has been observed in the auditory forebrain of female songbirds hearing attractive songs. C-Fos immunoreactive (Fos-ir) cell numbers were quantified here in the brain of female canaries that had been collected 30 min after they had been exposed for 60 min to the playback of SS or NS or control white noise. Fos-ir cell numbers increased in the caudomedial mesopallium (CMM) and caudomedial nidopallium (NCM) of SS birds as compared to controls. Song playback (pooled SS and NS) also tended to increase average Fos-ir cell numbers in the mediobasal hypothalamus (MBH) but this effect did not reach full statistical significance. At the individual level, Fos expression in CMM was correlated with its expression in NCM and in MBH but also with the frequency of calls that females produced in response to the playbacks. These data thus indicate that male songs of different qualities induce a differential metabolic activation of NCM and CMM. The correlation between activation of auditory regions and of the MBH might reflect the link between auditory stimulation and changes in behavior and reproductive physiology.
