The document discusses two types of neuronal circuits - homeostatic and allostatic circuits. The homeostatic circuit is a negative feedback loop that encodes resiliency and allows for effective self-regulation. The allostatic circuit is a positive feedback loop with no internal shut off mechanism, and encodes maladaptive generalizations and associations instead of resiliency.

2. Homeostatic Circuit
Negative feedback loop - Natural Shut-off

3. Homeostatic Circuit
Encoded in implicit memory systems:
• Resiliency Circuits
Effective self-regulation from all brain states to brain state 1
(“goal of homeostasis” and optimal functioning)
• Adaptive Generalizations
I do exist. I am not bad. I do have power. I can do good.
I can love. I am worthy. I am joy.
• Adaptive Associations
I get my “X” from “Z”.
X = survival (safety, love, protection)
Z = emotional connection (self-attunement)

4. Allostatic Circuit
Positive feedback loop - No Internal Shut Off

5. Allostatic Circuit
Encoded in implicit memory systems:
• Resiliency Circuits Not Encoded
Failure of self-regulation
suboptimal functioning and more“wear and tear”
• Maladaptive Generalizations
I do not exist. I am bad. I do not have power. I cannot do good.
I cannot love. I am not worthy. I cannot have joy.
•
Maladaptive Associations
I get my “X” from “Y”.
X = survival (safety, love, protection)
Y = substitute for emotional connection (default strategy)
