Many complex behaviors exhibited by social species are first learned by imitating the behavior of other more experienced individuals. Speech and language are the most widely appreciated behaviors learned in this way. Vocal imitation in songbirds is perhaps the best studied socially transmitted behavior, and research over the past few years has begun to crack the circuit mechanisms for how songbirds learn from vocal models. Studies in zebra finches are revealing an unexpected and essential role for premotor cortical circuits in forming the behavioral-goal memories used to guide song imitation, challenging the view that song memories used for imitation are stored in auditory circuits. Here, we provide a summary of this recent progress focusing on the What, Where, and How of tutor song memory, and propose a circuit hypothesis for song learning based on these recent findings.

The psittacine budgerigar Melopsittacus undulatus, a parrot species known to be a vocal learner, produces long and complex songs composed of different syllable types. Budgerigars can imitate heterospecific sounds as new song syllables, including human speech, but it is unclear how the imitative sounds affect the proportion of different syllables or high-order song structure, such as temporal pattern, which is characteristic of the budgerigar song. We analyzed recordings of songs from six adult male budgerigars with or without imitations of Japanese words to identify whether songs with imitations differed in structure from those without imitations.

Social interactions are crucial for imitative vocal learning such as human speech learning or song learning in songbirds. Recently, introducing specific learned modifications into adult song by experimenter-controlled reinforcement learning has emerged as a key protocol to study aspects of vocal learning in songbirds. This form of adult plasticity does not require conspecifics as a model for imitation or to provide social feedback on song performance.

Background: Previous studies have established that when vocal pitch in auditory feedback is perturbed unexpectedly, speakers typically produce opposing responses to correct the perceived error. Investigations comparing steady-pitch vocalizations and non-steady-pitch vocalizations have revealed that the extent of compensation is task-dependent. Nevertheless, the influence of musical expertise and the preference for adopting opposing or following responses during glissando vocalizations remain unexplored.

In contrast to humans, the location where sound is produced in birds is not the larynx, but rather the so-called "vocal box" (scientific term "Syrinx"). In some species the syrinx is located at the bifurcation point of the trachea into the two main bronchi (tracheal vocal head), while in some in the main bronchi (bronchial vocal head). During inspiration, part of the air flows into the lungs, and the part needed for singing flows into the air sacs adjacent to the lungs.

Objective: Ultrasonic vocalisations (USVs) emitted by rats may reflect affective states. Specifically, 50 kHz calls emitted during juvenile playing are associated with positive affect. Given that depression is characterised by profound alterations in this domain, we proposed that USV calls may configure a suitable tool for assessing depressive-like states.
