Background
Brains vary in their composition, both in size of regions and neuronal compositions, and so do behaviors. It has been known that there is variation between individuals, but what is still widely unstudied is the variation within individuals. This is called intraindividual variation, and how much an individual varies, in response to stimuli, is generally constant, making an individual more or less predictable in their behavior.
It has been studied the interaction between the variation of behavioral responses and the variation of brain composition, especially in fear-related behaviors in chickens. Thus I want to further explore this interaction, specifically with intraindividual variation.
Aims
To assess if a certain brain composition will result in a more or less predictable chicken.
