In this episode, Matthew speaks with Jesse Goldberg (@jesseGlab), Associate Professor and Robert R. Capranica Fellow in the neurobiology and behavior department at Cornell University.
They first cover Jesse's perspectives on some basics of neurobiology-- what he identifies as a brain's function and the brain's role in creating predictions and controlling movement. They then discuss the role of dopamine in an animal's learning and discoveries that Jesse's lab has made regarding the role of dopamine in song learning in zebra finches, in particular.
Then after the break they discuss Jesse's path from to neurobiology as well as the limitations and promises of the field of neurobiology.
A clarifying note to listeners, during our conversation the nervous systems of a marine animal - the sea squirt - becomes relevant. Although discussed as an example, we want to be clear that sea squirts retain some form of nervous system throughout their entire lives (though they digest large parts of their nervous system upon become sessile). For a more detailed look at the sea squirt's transition from mobile to sessile, check out this blog post.
This week's Two-Minute Takeaway comes from Andrew Legan (@AndrewLegan), a recently minted PhD from the NBB department at Cornell. Read Andrew's work on odorant receptor expansion in paper wasps here.
