A great deal of progress has been made toward understanding the molecular basis for critical periodsunderlying cortical processing of primary sensory information. Whether these processes extend tosensorimotor integration and how sub-cortical regions such as the basal ganglia may contribute is unknown.
Thanks to decades of neuroethological study, birdsong is the leading model for human speechdevelopment, having established numerous key parallels to human vocal learning. These include sharedcritical periods and reliance on cortico-basal ganglia circuitry. A great experimental attribute of the songbirdmodel is that within cortex, basal ganglia and thalamus, sub-regions dedicated to vocal learning are visiblyclustered, forming tractable targets for linking brain and behavior. We have leveraged this organization toidentify spatio-temporal profiles of the song-dedicated transcriptome in the basal ganglia. Our findingssuggest a new model whereby the intersection of learning related gene co-expression modules intersectwith song related modules to provide a permissive nexus for vocal learning.

How learning and interaction create and destroy linguistic structureKenny SmithHuman languages are culturally-transmitted systems, which persist in populations via a repeated cycle oflearning and use, where learners learn from linguistic data which represents the communicative behaviourof other individuals who learnt their language in the same way. Languages evolve as a result of this cycle oflearning and use, and are therefore the product of a potentially complex interplay between the biases ofhuman language learners, the communicative functions which language serves, and the ways in whichlanguages are transmitted in populations. In this talk I will present a series of experiments, based aroundartificial language learning, dyadic interaction and iterated learning paradigms, which allow us to explorethe relationship between learning and use in shaping linguistic structure. I’ll summarise some of our olderwork showing how and when linguistic structure is created through this process, then present some recentwork using these techniques to test hypotheses about the mechanisms linking population demographicsand linguistic complexity, in particular exploring why it might be the case that languages spoken in largerpopulations are relatively simple.

Syntax in the light of evolution:Intermediate stepping stones toward hierarchy, Move, and recursionLjiljana ProgovacIt is often stated that the nature of human language cannot be fully understood without reference to itsevolution. If so, then not only should theories of language evolution be grounded in linguistic analysis, but,also, linguistic theories should accommodate what is already known or hypothesized about languageevolution. In this lecture I consider how one such (theoretically grounded) decomposition of syntax leads toa deeper understanding of attested syntactic phenomena, both those well-supported in syntactic theory (e.g.
the small clause foundation of sentences), and those which remain largely unresolved (e.g. islandhood). Theproposal is that proto-syntax started flat, intransitive, non-recursive, and static (without Move), and thatthese rigid but robust beginnings still pervade the fabric of modern syntax, producing some intricate effectsand echoes of the past. Here I explore the fluidity/overlaps of structure found in e.g. (i) parataxiscoordination-subordination progressions, as well as (ii) intransitive-middle-transitive progressions. Both ofthese continuums are of relevance to the gradual emergence of the (delicate and decomposable) hallmarksof modern syntax, which include hierarchy, Move, and recursion. The discussion will also point to howevolutionary proposals of this kind can be tested, communicating the results of an fMRI experiment.
