Collective action or individual choice: Spontaneity and individuality contribute to decision-making in Drosophila.

Our own unique character traits make our behavior consistent and define our individuality. Yet, this consistency does not entail that we behave repetitively like machines. Like humans, animals also combine personality traits with spontaneity to produce adaptive behavior: consistent, but not fully pr...
