Can cortex be used as a pain pill?

Can cortex be used as a pain pill?

Willow bark? Yes.: Think flesh not bone! wellness is vital to controlling any headache or pain issue. Magnesium is also vital. It will help relax the associated muscles, decrease stress, stabilize sleep and help other meds and therapy to work efficiently. Self or profess massage, chiropractor, yoga, heat, stretching all are needed. My favorite in my practice is acupuncture and myofascial tissue release. ...Read more

Breathlessness in humans activates insular cortex. What does this mean?

Breathlessness in humans activates insular cortex. What does this mean?

You read a paper: http://www.ncbi.nlm.nih.gov/pubmed/10923655 some people were put in a color pet scanner and were made to hold their breath. The signal from the insular cortex changed, as it does from other uncomfortable things. The results were published in an obscure journal. This is not cutting-edge science or surprising, though i'm glad someone does studies like this. ...Read more

How can taking cortisone damage the adrenal cortex?

How can taking cortisone damage the adrenal cortex?

Suppresses it: Taking the hormone that is normally produced by the adrenal cortex means that it no longer produces it (negative feedback). If you suddenly stop taking the medication, your body needs several days to weeks to begin to make hormone again. So, if you are taking cortisol you need to taper the dose to make sure you give your glands the chance to being producing again. ...Read more

Does cortisone in high doses damage the adrenal cortex?

Does cortisone in high doses damage the adrenal cortex?

Prolonged use, yes: Using steroid for a brief period of time of less than a few weeks probably won't have long term effect, but prolonged use will suppress it--it loses the ability to produce the steroid. Thus folks who need to use steroid for an extended of time often need to remain on it. The length of time varies, but using more than 3 wks typically would need a slow wean. Consult doc. Good luck. ...Read more

How could taking cortisone chronically damage the adrenal cortex?

How could taking cortisone chronically damage the adrenal cortex?

Causing hypoadrenal: The adrenal cortex makes Hydrocortisone under the influence of acth from the pituitary. Too much cortisone will suppress the pituitary so it will not stimulate the adrenal to produce its own steroid. After taking cortisone in tapering amounts the adrenal will eventually wake up. ...Read more

Does anterior cingulate cortex turn off amygdala completely or simply make us unable to see emotions?

Does anterior cingulate cortex turn off amygdala completely or simply make us unable to see emotions?

Network analysis: Neural networks exist in the brain subserving certain functions, often specific to that network. Anterior cingulate (acc) and amygdala are in one such circuit. Disrupting communications between the two will cause changes in each component. Re-establishment of communications by re-wiring the brain (plasticity) may cause restoration of function but it may be abnormal-hence altered emotionality. ...Read more

Regarding left primary motor cortex to biceps femoris, what type of information is relayed between these regions?

There are many-: -you think of contracting the muscle subconsciously brain sends impulse to muscle proprioception receptors lets the brain know where the leg is in time & space.feed back lets brain know how hard you need it to contract. All is close to the speed of light.all this info goes back & forth instantaneously. It's much more complicated but excluding electrolytes involved takes a book. ...Read more

I had an mri. The impression on the report said minimal area of gliosis within the right insular cortex. What should I do?

I had an mri. The impression on the report said minimal area of gliosis within the right insular cortex. What should I do?

Gliosis: Is rather non-specific brain inflammation, encountered in a multitude of neurologic conditions from post trauma scarring to multiple sclerosis or neurodegenerative disease. Your best resource will be your neurologist in trying to connect your actual symptoms/ the reason for the test with the MRI findings in trying to assign it to one of the above mentioned conditions. ...Read more

I am a woman.Aged 33. Have a hyperechoic lesion measuring 12.4 *11.8mm noted in left renal cortex. How can this be treated?

I am a  woman.Aged 33. Have a hyperechoic lesion measuring 12.4 *11.8mm noted in left renal cortex.
How can this be treated?

The vast majority: of the time, this finding represents a benign angiomyolipoma and requires no treatment. The ultrasound appearance is not diagnostic, but CT or MRI can usually make a definitive confirmation of the diagnosis due to certain unique features of the nodule on those modalities. ...Read more

What hormone is produced by the adrenal cortex?

Rather 3 not 1: In a nutshell: 1- Cortisol, which is cortisone important for several metabolic functions,its release is regulated by the pituitary gland in the brain, 2- Aldosterone, plays a role in controlling blood pressure and balancing salts in circulation, and 3- acts a secondary site for producing Androgens, as testosterone and others, which have several effects on muscle mass and cell growth, ...Read more

What part of the cortex is the absence seizures are?

Absence seizures: Absence seizures are a type of generalized seizure, perhaps with some relevance of the centro-temporal area on both sides. A complex partial seizure, which may appear similar to an observer, can have a focal onset, like the temporal lobe. Hope that helps! ...Read more
