Molecular Nature

In birds and higher mammals, auditory experience during development is critical to discriminate sound patterns in adulthood. However, the neural and molecular nature of this acquired ability remains elusive. In fruit flies, acoustic perception has been thought to be innate. Here we report, surprisingly, that auditory experience of a species-specific courtship song in developing Drosophila shapes adult song perception and resultant sexual behavior. Preferences in the song-response behaviors of both males and females were tuned by social acoustic exposure during development. We examined the molecular and cellular determinants of this social acoustic learning and found that GABA signaling acting on the GABAA receptor Rdl in the pC1 neurons, the integration node for courtship stimuli, regulated auditory tuning and sexual behavior. These findings demonstrate that maturation of auditory perception in flies is unexpectedly plastic and is acquired socially, providing a model to investigate how song learning regulates mating preference in insects.

The expression of bird song is expected to signal male quality to females. ‘Quality’ is determined by genetic and environmental factors, but, surprisingly, there is very limited evidence if and how genetic aspects of male quality are reflected in song. Here, we manipulated the genetic make-up of canaries ( Serinus canaria ) via inbreeding, and studied its effects upon song output, complexity, phonetics and, for the first time, song learning. To this end, we created weight-matched inbred and outbred pairs of male fledglings, which were subsequently exposed to the same tutor male during song learning. Inbreeding strongly affected syllable phonetics, but there were little or no effects on other song features. Nonetheless, females discriminated among inbred and outbred males, as they produced heavier clutches when mated with an outbred male. Our study highlights the importance of song phonetics, which has hitherto often been overlooked.

Caudomedial Nidopallium

ABSTRACTBirdsong, like human speech, is learned early in life by first memorizing an auditory model. Once memorized, birds compare their own burgeoning vocalizations to their auditory memory, and adjust their song to match the model. While much is known about this latter part of vocal learning, less is known about how initial auditory experiences are formed and consolidated. In both adults and developing songbirds, there is strong evidence suggesting the caudomedial nidopallium (NCM), a higher order auditory forebrain area, is the site of auditory memory consolidation. However, the mechanisms that facilitate this consolidation are poorly understood. One likely mechanism is 17β-estradiol (E2), which is associated with speech-language development and disorders in humans, and is abundant in both mammalian temporal cortex and songbird NCM. Circulating E2 is also elevated during the auditory memory phase, and in NCM immediately after song learning sessions, suggesting it functions to encode recent auditory experience. Therefore, we tested a role for E2 production in auditory memory consolidation during development using a comprehensive set of investigations to ask this question at the level of neuroanatomy, neurophysiology, and behavior. Our results demonstrate that while systemic estrogen synthesis blockade regulates juvenile song production, inhibiting E2 synthesis locally within NCM does not adversely affect song learning outcomes. Surprisingly, early life E2 manipulations in NCM modify the neural representations of birds’ own song and the model tutor song in both NCM and a downstream sensorimotor nucleus (HVC). Further, we show that the capacity to synthesize neuroestrogens remains high throughout development alongside substantial changes in NCM cell density across age. Taken together, these findings suggest that E2 plays a multifaceted role during development, and demonstrate that contrary to prediction, unilateral post-training estrogen synthesis blockade in the auditory cortex does not negatively impact vocal learning. Acute downregulation of neuroestrogens are therefore likely permissive for juvenile auditory memorization, while neuroestrogen synthesis influences communication production and representation in adulthood.
