Term
what are the fucntions of the threat evaluation system?
Definition
Threat assessment and response:
Detection;
Discrimination;
Rapid, coordinated response; Return to baseline;
Memory function
Term
what are you detecting?
Definition
External stimuli (exteroception)
and

Internal stimuli (interoception)
Term
how do you look for external stimuli?
Definition
Sensory systems - the 5 senses
Precise, but limited in range
Term
how do you look for internal stimuli?
Definition
proprioception (less precise) and visceral sensations (interal) (imprecise)
Term
What is the point of discriminatin?
Definition
Sort relevant from irrelevant stimuli:
Relevant (Threatening vs. Desirable);
Novel versus known;
Harmful versus benign
Term
what are rapid and coordinated responses?
Definition
Conscious attention & appraisal
(Pre-emptive processing);
Automatic behaviors
(Innate;
Learned;
(Conditioned;
Practiced;))
Autonomic support
Term
After a threat response, how do you return to baseline?
Definition
Through de-escalation: Conscious decisions;
Contingencies - reward/punishment;
Automatic behaviors
Time limited - habituation;
Autonomic support
Homeostasis - negative feedback
Term
why do you return to baseline?
Definition
threat responses are not sustainable
Term
how does memory help threat?
Definition
Enhance effectiveness of future responses:
Change detection sensitivity;
Improve recognition of threats;
Modify innate and automatic responses;
Speed recovery
Term
what is biologicall involved in anxiety?
Definition
Stress response:
Locus ceruleus
(Noradrenergic, sympathetic activation)
Limbic system (Papez)::
Hippocampus - thalamus - cingulate
Integrated system:::
Prefrontal cortex (PFC)
Central nucleus of the amygdala (CNA)
Term
What causes behavioral inhibition?
Definition
Timidity and withdrawal in novel situations;
Exaggerated autonomic & HPA responses;
Slow habituation
Term
what is central CRF?
Definition
corticotrophin releasing factor
