1.) Is there any case, or paper that has looked at the parallel between the structure and function of the nervous system, and cognitive biases ?

This paper deals with the core theme of A Neural Network Framework for Cognitive Bias that carries the prevailing theoretical perspectives on the origin of heuristics and cognitive biases.

1.) Is there any case, or paper that has looked at the parallel between the structure and function of the nervous system, and cognitive biases ? In particular, is there evidence to show that some neurotransmitters/molecules actually have the biggest influence on our biases?
2.)Conversely, is the other way round true too? eg. does following/being part of a crowd release certain reward molecules? Are there any medical/scientific examples or research papers?
3.) Finally, I would love to finish with an interesting case/anecdote from the latest in neuroscience and behavior/biases .. is there something you have come across or that people are talking about in your profession?
