Young songbirds babble before they can mimic an adult's song, much like their human counterparts. Now, in work that offers insights into how birds - and perhaps people - learn new behaviors, MIT scientists have found that immature and adult birdsongs are driven by two separate brain pathways, rather than one pathway that slowly matures.
The work is reported in the May 2 issue of Science.
"The babbling during song learning exemplifies the ubiquitous exploratory behavior that we often call play but that is essential for trial-and-error learning," comments Michale Fee, the senior author of the study and a neuroscientist in the McGovern Institute for Brain Research at MIT and an associate professor in MIT's Department of Brain and Cognitive Sciences.
