HPA Axis

Inherited anxiety from parents runs through a PFC-amygdala-brainstem circuit. See how genes and learned autonomic patterns transmit it, and what...

Fixing a broken circadian rhythm means re-aligning the SCN master clock with your organs. See how light, temperature, and meal...

Loneliness and inflammation run on the same switch: Cole's CTRA rewires immune cells to flood the body with IL-6 and...

Waking at 3am is the cortisol-melatonin crossover firing early: HPA hyperactivation drives a pre-dawn cortisol spike that fragments REM sleep.

Can't sleep after a breakup? Your HPA axis flipped the cortisol rhythm and your locus coeruleus runs nocturnal threat-scanning at...

Epigenetic inheritance of family trauma is real: DNA methylation on NR3C1 and FKBP5 passes stress biology across generations, and it...

Cortisol co-regulation in families explains why your nervous system still syncs with your parents: HPA axis, vagus nerve, and the...

Anxious, avoidant, and disorganized brains grieve on different circuits: attachment style breakup recovery runs distinct timelines and risks.

Going no-contact triggers attachment-circuitry withdrawal and a three-phase brain recalibration. Dr. Sydney Ceruto maps the timeline.

Divorce brain fog is chronic stress suppressing your prefrontal cortex and hippocampus during the months you most need clear legal...

PTSD after infidelity involves the same tripartite neural disruption as combat PTSD: amygdala hyperactivation, hippocampal shrinkage, prefrontal drop.

Hypervigilance after infidelity is your amygdala recalculating threat probability, not a sign you're broken. The neuroscience of betrayal surveillance.
