“…Together these findings suggest that males and females, just like in spatial memory, use different learning strategies in vocal learning as suggested by Riebel (2016). They rely on different parts of the song control system and use different mechanisms to manifest neuroplasticity in their respective song control system.…”

Traditionally, research unraveling seasonal neuroplasticity in songbirds has focused on the male song control system and testosterone. We longitudinally monitored the song and neuroplasticity in male and female starlings during multiple photoperiods using Diffusion Tensor and Fixel-Based techniques. These exploratory data-driven whole-brain methods resulted in a population-based tractogram uncovering microstructural sexual dimorphisms in the song control system and beyond. Male brains showed microstructural hemispheric asymmetries, whereas females had higher interhemispheric connectivity, which could not be attributed to brain size differences. Only females with large brains sing but differ from males in their song behavior by showing involvement of the hippocampus. Both sexes experienced multisensory neuroplasticity in the song control, auditory and visual system, and the cerebellum, mainly during the photosensitive period. This period with low gonadal hormones might represent a ‘sensitive window’ during which different sensory and motor systems in telencephalon and cerebellum can be seasonally re-shaped in both sexes.

“…Prior studies demonstrated that males generally outperform females in spatial memory performance tasks, but rely on different strategies in learning such cognitive tasks in both mammals and songbirds ( Kosarussavadi et al, 2017 ; Rensel et al, 2015 ; Tropp and Markus, 2001 ). Sexually different learning mechanisms have also been suggested in vocal learning in songbirds ( Riebel, 2016 ). Few studies have looked at the role of the hippocampus in song behavior in zebra finches.…”

We longitudinally monitored the song behavior and neuroplasticity in male and female starlings during multiple photoperiods using Diffusion Tensor and Fixel-Based techniques. These exploratory data-driven whole-brain methods resulted in a population-based tractogram confirming microstructural sexual dimorphisms in the song control system. Furthermore, male brains showed hemispheric asymmetries in the pallium, whereas females had higher interhemispheric connectivity, which could not be attributed to brain size differences. Only females with large brains sing but differ from males in their song behavior by showing involvement of the hippocampus. Both sexes experienced multisensory neuroplasticity in the song control, auditory and visual system, and cerebellum, mainly during the photosensitive period. This period with low gonadal hormone levels might represent a 'sensitive window' during which different sensory and motor systems in the cerebrum and cerebellum can be seasonally re-shaped in both sexes.

“…Applications to neurobiology and physiology. Compared with male bird song, we know little about the neurobiological and physiological mechanisms that control differences in female song (Riebel 2003, 2016. Therefore, there is ample room for research into the mechanistic, neurological, and hormonal regulation of female bird song production and development.…”

“…Female song, however, is currently underrepresented, both in the literature and in biological (sound) collections. Investigating female song in conjunction with male song has great potential to advance both basic and applied research in the lab and in the field (Price 2015, Riebel 2016, Hall and Langmore 2017. For example, female song data could enable detailed comparative studies of neural song control or could allow sex-specific avian monitoring (Brenowitz 1997, Odom andMennill 2010).…”
