nonessential physiological processes shut
down (i.e. digestion &
reproduction), energy
is channeled into a host
of functions preparing
for rapid action.
When a person or animal confronts actual (or
perceived) danger situations, what neurochemical
and hormonal reactions start to occur?
2. cortex, amygdala Stressful events are perceived at the ,
processed at the , which then activates
lower brain areas & puts the limbic system on alert
3. norepinephrine when there is imminent danger, a burst of excitation originates from the locus coeruleus which
releases , which results in instantaneous hypervigilance.
4. limbic system and hypothalamus by activating the SNS, HTA, or
HPA
5. chloride
what is responsible for the release of stress hormones?
ions act as a brake and dampen the
limbic alert
6. benzodiazepines enhance the flow of negative (chloride)
ions which results in widespread calming in may
areas of the brain
7. serotonin excitability in the locus coerulues is also mediated
by
8. inhibitory in the Locus Coeruleus, serotonin is
