A Heightened Stress System |
As discussed in Chapters and sustained stress changes the bodys life strategy It convinces |
the body that the environment it was born into is particularly lifethreatening Scientists refer |
to such environments as high in extrinsic mortality This kind of environment communicates |
to the organism on a cellular level that the probability of it being able to live a long and happy |
life is low The genes then reprogram the body to deal with a short and grisly one This changes |
your mortal shell from a slowburning candle into a firecracker Your body expends all its energy |
upfront because it doesnt expect to live for long This happens at the expense of longterm |
energetic investments such as healing the immune system learning reproductive functioning |
affiliation and investing time and energy in offspringt For example chronic anxiety inhibits |
your bodys ability to protect itself from oxidation which is a process that acts on your cells in |
the same way that rust acts on metal It also contributes to aging by keeping the body from |
repairing its telomeres the protective caps at the end of your chromosomes reducing the |
number of times your cells can divide |
As you know when stress goes on for too long it results in a chronically heightened fear |
and startle response The brain is retuned to enhance performance during lifethreatening |
situations and facilitate cautiousness and hypervigilance traits that would have been highly |
adaptive during extended periods of dire stress in prehistoric environments These changes |
cause the stress response to become more pronounced and more easily triggered The brain |
center that triggers stress the amygdala has its own innate response pattern to chronic stress |
Lets learn more about this almondsized nucleus that acts as yet another biological repository |
of trauma |
The Amygdala Recognizes Threats |
As we learned in Chapter threats are recognized by the amygdala This unconscious |
subcortical area becomes active once it perceives a stimulus or a group of stimuli together as |
dangerous The amygdala responds quickly and automatically to the inputs it receives from the |
eyes ears and other sense organs If the threat is sufficient it broadcasts the fear signal to the |
rest of the brain It can do this unconsciously a glimpse of a looming object or visually the |
view of a bus barreling toward you The recognition of an abstract stressor knowledge that |

you missed your bus involves the prefrontal cortex which indirectly alerts the amygdala |
Either way once the amygdala is activated it will signal the hypothalamus which initiates fight |
or flight |

Illustration A Cross section of the brain with amygdala revealed You actually have two amygdalae one in |
each cerebral hemisphere B Three fear pathways to the amygdala The unconscious pathway travels from the |
eye to the thalamus to the amygdala The visual pathway travels from the eye to the thalamus to the visual |
cortex to the amygdala The thinking pathway travels from the prefrontal cortex to the amygdala |
Amygdala |
If the amygdala is strongly and repeatedly activated over the course of several weeks its |
default level of activity will increase Over months of repeated activation the amygdala |
develops stronger connections with other brain areas intensifying its influence It also increases |
in overall size This enhanced priority given to the amygdala causes the animal to react to |
every seemingly threatening stimulus as if it were a full threat |
The amygdalas job is to decide whether a pattern of inputs looks like something that |
turned out badly in the past However it does not use reason or conscious deliberation to do |
this Rather it engages in simple pattern matching in which it adds up seemingly bad inputs to |
see if they sum to a threshold If the inputs surpass this threshold the amygdala triggers the |
sympathetic nervous system Thus our feelings of dread are not prompted by logical thinking |
Instead they are initiated by the amygdalas eccentric way of determining statistics and |
probability For example an offenders voice clothes name or cologne could subliminally |
reinstate an amygdala highjack |
Allow me to provide an example of how the amygdalas form of logic is susceptible to |
mistakes One day when was in a lousy mood picked up the phone and the caller asked to |
speak to my roommate The next day when heard their voice again it made me angry and |
realized my prior bad mood had biased me against the caller for no good reason Because my |
brain made this unconscious negative association hearing the voice later triggered the same |
negative emotions It was illogical and unfair to the caller But my first impulse was to trust it |
unquestioningly We accept the amygdalas alarm bells as a type of foreboding intuition |
Negative emotions usually feel valid and impelling but they are often invalid and illusory |
This is why we should question them rather than act on them impulsively Especially after |
you experience a series of stressors the amygdala will influence your thinking to be |
delusionally negative |
PROGRAM PEACE Self Care Exercises to Reprogram Your Mind and Body |
When activity in the amygdala surges the brain is temporarily retuned to perceive |
everything as troublesome For instance it increases the tendency to perceive ambiguous |
events as bad such as criticism when none is intended or hostility from a neutral face This is |
the opposite of a manic episode which causes people to perceive everything as a gleeful lucky |
coincidence People with mania often feel like cars on the freeway move to let them through |
everyone is their best friend and everything goes their way On the other hand chronic stress |
makes us more likely to succumb to road rage and the feeling that everyone and everything is |
against us Whenever start to feel disheartened try to remember that neurochemicals can |
paint over reality |
You may have noticed that after one negative interaction you are much more likely to get |
stressed out about other completely unrelated things With the exception of living in a |
warzone this displaced negative thinking is irrational in the modern world Interestingly though |
it may not be irrational from an ecological standpoint It was beneficial for mammals to be |
prepared for the worst during bad times Just imagine what life would have been like for early |
mammals in the Jurassic and Cretaceous periods |
When there are predators on the loose or natural catastrophes strike they are rarely |
quickly resolved For furry varmints from possums to porcupines to panthers it makes sense to |
become scared and remain paranoid From a modern perspective however it is preposterous |
to generalize anxiety to whatever your mind turns to Dont let one unfortunate scenario lead |
to a domino effect of suspicion and dismay Notice when you carry negative emotions from one |
thought over to another When you realize it try to tell yourself that the negativity may feel |
compelling but that it is probably just residual and misattributed emotion |
Stress and Cortisol The MindBody Connection |
Stand porter at the door of thought Admitting only such conclusions as you wish realized in bodily results you will |
control yourself harmoniously Mary Baker Eddy |
When the amygdala decides it has perceived a stressful stimulus it triggers the hypothalamus |
The hypothalamus mobilizes the sympathetic nervous system leading to rapid breathing |
