Description

The amygdala (yellow) is our emotional memory store. This is where our preverbal memories reside (which are sometimes surfaced during psychoanalysis). The amygdala is responsible for our split-second responses to emotionally-charged situations – those times where we don’t think about what we are going to do; we just up and do it. Often, situations our amygdala perceives as threatening can lead us to the “red line” continuum of responses, from flight to fight.

The reptilian brain is where our survival mechanisms exist. Threats activate this portion of our brain – and the amygdala can alter the circulation of blood flow for a split second away from the neocortex (so no time-consuming analysis can be performed) to either the upper or lower torso, depending on the determined response. The loss of blood flow to the neocortex can also happen to a lesser degree during a time of sustained stress, thus leading to more subtle but pervasive “redline” behaviors. So it is perhaps easy to see why we act unreasonably when we are stressed. For executives, this kind of stress can trigger survival-based behaviors (power plays, knowledge hording, peer distrust, etc.) that would be less likely were they not at this stress level.

“If we don’t have a green-line way to process stress & fear, we’ll drop to the red line.”
