In a discussion about what decisions are, John Krakauer emphatically pronounced that “decisions happen for reasons”, in answering ‘no’ to my question if it wasn’t a decision with which foot to start walking from a stand-still. A recent article from the laboratory of Carolina Rezaval in Birmingham studied a decision-making process in male Drosophila fruit flies where the reasons for each decision seemed apparent.

I was very excited when our latest research paper came out, after all, I was confident our 30-year-long search for the sites of plasticity in the form of motor learning we study was coming to an end. In this work, we were fairly confident that underlying the type of learning we study was a novel form of plasticity in a very specific set of motor neurons in the ventral nerve cord of the flies we use for our research.

We are looking for a PhD student interested in the functional, molecular and structural profile of neuronal circuits underlying learning, memory and behavior. In a 30-year research effort (lay summary, paper), we have recently identified a new gene (atypical PKC, aPKC) necessary for a form of motor learning in the fruit fly Drosophila and in which neurons it is required.

It was my freshman year, 1991. I was enthusiastic to finally be learning about biology, after being forced to waste a year in the German army’s compulsory service at the time. Little did I know that it was the same year a research paper was published that would guide the direction of my career to this day, more than 30 years later. Many of the links in this post will go to old web pages I created while learning about this research.

It’s the time of the year again where 30,000 neuroscientists head to the US to talk neuroscience. This year the big annual conference is in Washington, DC, one of the three cities able to host this large event. Our first poster will be up on Tuesday morning and shows results from operant self-stimulation experiments using optogenetics and dopaminergic neurons.
