Each tells part of the brain story (click on their photo for video)

Dan Gilbert explains the neuro-biology of change and why "human beings are works in progress that mistakenly think they are finished". 

Dan Siegel shows a simple model of the brain to distinguish the functions of the brain stem, limbic, the neo cortex, and the pre-frontal cortex (PFC).

David Rock explains why the rational is over-rated, the see-saw interaction between limbic and PFC, and how you can manage an unhelpful limbic response

Jill Bolte-Taylor explains how our right brain sees the world differently to the left, connecting better to our own limbic and to others.

VS Ramachandran describes mirror neurons which allow us to experience what others are feeling - the mechanics of empathy (limbic resonance).

Norman Doidge explains that neuroplasticity means the brain isn't "hard-wired". Developmental experiences literally change our brain structures.

"A lot of what we think is spectacularly wrong" Norman Doidge
