Developmental song learning in the zebra finch
Developmental learning (for example, speech acquisition in human infants) takes place early in life but its effects may last the entire lifetime of the individual. Developmental learning is difficult to study because the behavioral changes involved span many time scales: The challenge is to relate the developmental parameters to behavioral changes, which can occur within hours as well as across...
متن کاملBehavior-linked FoxP2 regulation enables zebra finch vocal learning.
Mutations in the FOXP2 transcription factor cause an inherited speech and language disorder, but how FoxP2 contributes to learning of these vocal communication signals remains unclear. FoxP2 is enriched in corticostriatal circuits of both human and songbird brains. Experimental knockdown of this enrichment in song control neurons of the zebra finch basal ganglia impairs tutor song imitation, in...
متن کاملOdour-based natal nest recognition in the zebra finch (Taeniopygia guttata), a colony-breeding songbird.
Passerine birds have an extensive repertoire of olfactory receptor genes. However, the circumstances in which passerine birds use olfactory signals are poorly understood. The aim of this study is to investigate whether olfactory cues play a role in natal nest recognition in fledged juvenile passerines. The natal nest provides fledglings with a safe place for sleeping and parental food provision...
متن کاملCirculating breeding and pre-breeding prolactin and LH are not associated with clutch size in the zebra finch (Taeniopygia guttata).
Clutch size is a fundamental predictor of avian fitness, widely-studied from evolutionary and ecological perspectives, but surprisingly little is known about the physiological mechanisms regulating clutch size variation. The only formal mechanistic hypothesis for avian clutch-size determination predicts an anti-gonadal effect of circulating prolactin (PRL) via the inhibition of luteinizing horm...
متن کاملDopaminergic regulation of orexin neurons.
Orexin/hypocretin neurons in the lateral hypothalamus and adjacent perifornical area (LH/PFA) innervate midbrain dopamine (DA) neurons that project to corticolimbic sites and subserve psychostimulant-induced locomotor activity. However, it is not known whether dopamine neurons in turn regulate the activity of orexin cells. We examined the ability of dopamine agonists to activate orexin neurons ...
