How does cerebral hypoxia cause euphoria?

The mechanism by which the conscious feeling of euphoria is felt is still unknown. Due to the multiple methods by which euphoria can occur it is likely a 'natural' state of the brain that can be triggered either naturally or unnaturally. It is also likely that it occurs in the same brain regions responsible for mood. https://en.wikipedia.org/wiki/Reward_system You'll note that many of the structures connected to the reward system are glutamatergic interneurons. This means that excess glutamate can trigger the reward system to produce euphoric feelings. In cerebral hypoxia the lack of oxygen results in a lack of energy for the cell. Mainly this results in the switching off of the sodium / potassium pump. A nerve cell fires by moving sodium outside the cell and potassium inside the cell to create concentration gradients, that are then reversed during an action potential. If the pump does not have oxygen then this mechanism stops. This results in an increase in e...

The secret reason we treat strep throat

Chad Hayes, MD You may have read my recent post about ear infections and how they are over-diagnosed and over-treated. Guess what—ear infections are not alone. Strep throat is another common pediatric infection that is over-diagnosed and over-treated. In adult patients, it’s easy to make a case for not treating it at all. And although kids aren’t just little adults, and the evidence is a little less clear-cut, pediatricians may need to back off, too. I know you already don’t believe me (nor do some of my patients…or my mother), but let me make my case: Group A Streptococcal pharyngitis (which will henceforth be referred to as “strep throat”) is a sore throat caused by a type of bacteria called Streptococcus pyogenes. The same organism causes other infections as well, but I’ll focus on the throat. Common symptoms seen with strep throat include sore throat, fever, headache, and nausea. This disease is more common in school-age children and teenagers than it is in adults, but rarely se...

Top 49 Ways to Increase Myelin Naturally and Boost Intelligence

Myelin is an important part of the nervous system and is vital for optimal cognitive function. Read more below to learn how to increase myelin in your body. Introduction Myelin is a sheath made out of fats and proteins that wraps around the axon (end) of a nerve cell. It helps the nervous system function properly ( R ,  R ). It improves the conduction of action potentials, which are needed to send information down the axon to other neurons ( R ). The myelin sheath increases the speed of impulses in neurons. It facilitates conduction in nerves while saving space and energy ( R ). Demyelination happens when the nerves lose the myelin sheath that insulates them. This can cause many neurodegenerative diseases or nerve and brain damage. Defective myelin sheaths can also cause nerve disorders ( R ). It’s thought that inflammatory cytokines reduce myelination ( R ). Myelin Increases Intelligence Since myelin transmits neuronal signals, Myelin plays a critical role in...
