QuestionAnswer
Anxiety Disorders 9 million people 18-54 y.o. – Panic DO, OCD, PTSD, Phobias, GAD
Panic Disorder Can be triggered artificially; Caffeine; Lactic acid administration • Breathing elevated CO2;Overactive central nucleus?; Early life stress; Rat pup study—CRF
Anxiety Treatment Benzodiazepines, GABA receptors, SSRI better
The stress response activation of the sympathetic nervous system which activities the adrenal medulla which secretes Adrenaline and noradrenaline, leading to increased physiological arousal. Also, activation of the HPA axis.
HPA axis Activation of hypothalamus leads to release of hormones (CRH) that travel through the bloodstream to the pituitary gland-secretes hormones (ACTH)-activates the adrenal gland (release cortisol). Increases energy, suppresses inflammatory/immune response
Cortisol Adrenal Glands; Stress hormone; Aging, stress related disease, etc.; Dose dependent with fear; Negative feedback for ‘fight or flight’ response; Higher in acute stress among persons who go on to develop PTSD/depressive disorders
“Normal” Fear Response Alarm phase; Serum levels of cortisol, CRF and adrenaline return to baseline within a few hours
"Abnormal” Fear Response Intractable, Chronic, Exaggerated, PTSD; No return to baseline, increased amygdalar activity on SPECT and fMRI, Increased HPA activity (hyperactivity), Dysregulation of HPA=risk for depression, anxiety disorders and PTSD
"Abnormal” Fear Response continued Hypersecretion of CRF Change in hippocampal & amygdalar volume ; Sensitizes HPA axis
Temporal Interference Electrical Stimulation; Non-invasive deep brain stimulation; Better targeted than repetitive transcranial magnetic stimulation;
Transcranial Lasers Near-Infrared (IR) radiation or photobiomodulation (PBM) therapy; Light at red and near-infrared wavelengths—now LED for home use; Activates cytoprotective, anti-oxidant and anti-apoptotic effects in the cells—even with tinfoil
Nanotechnology various nano size carriers that address brain drug delivery challenges due to BBB; target particular disease, Alzheimer's, brain tumor, epilepsy
photobiomodulation using red and near-infrared light is a, non-invasive treatment for neuropathic pain by reducing inflammation and promoting nerve repair. It stimulates cellular energy (ATP) to alleviate pain. antagonizes antioxidant in mitochondria
The Singularity when technology transcends biology; Ray Kurzweil; Transhumanism (abbreviated as H+ or h+) “Humans will most experience gradual conversion of their brain are augmented with neural implants, increasing their proportion of non-biological intelligence

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
