  The origins of spontaneous movements have been investigated in human as well
as in other vertebrates. Studies have reported an increase in neuronal activity
one second before the onset of a given movement: this is known as readiness
potential. The mechanisms underlying this increase are still unclear. Zebrafish
larva is an ideal animal model to study the neuronal basis of spontaneous
movements. Because of its small size and transparency, this vertebrate is an
ideal candidate to apply optical recording methods. In order to understand what
neuronal activity causes the execution of a specific tail movement at a given
time, we will mainly use a prediction approach.
