Description www.hunterkane.com Till 1994 we believed —a wild animal, whatever it happens to be—came through to a relay station called the thalamus, the thalamus sends the information to the cortex, or the pre-frontal cortex. What was believed was the cortex initiates an automatic knee-jerk response: Behavioural - we jump back; Physiological - we increase our blood pressure and adrenalin to fight or flight, and then an Immunological response in case the system is damaged in some way. But in fact, back in 1994, Joseph LeDoux and his team discovered this pathway to this guy called the amygdala. Now the amygdala is a key emotional centre in the brain, and what they discovered was that it was the amygdala that initiates the response, not the cortex. In fact, even more important than that, the amygdala initiates the response before the information reaches the cortex. Now, because the amygdala is there to keep us alive, it's actually not very accurate, but very high speed, and the cortex is very accurate, but relatively slow. So, we've initiated a response; activated a response before the information even reaches the cortex. Why does that matter? Well, the cortex is where we learn new things; it's where we learn how to behave. So what we call default behaviours today—and a perfect example of that would be road-rage—so we might get involved in some altercation on the road, we get very frustrated and angry with somebody, then a moment later we realise we perhaps overreacted; because that's <b>...</b>Medicine, brain, Amygdala, hypothalamus, cortex, Adrenaline, Acetylecholine, DHEA, Cortisol, fight, flight, stress, hans, selye, gutsThe Science of Stress Physiology Emotions Fight Flighthttp://gdata.youtube.com/feeds/api/videos/8CL2hetqpfg2006-03-17T15:58:06.000Z2012-05-28T09:13:16.000ZGiant centipede eating mouse.A giant centipede, scolopendra gigantea robusta, killing and eating a mouse.
