Lower Brain Stem Function
For life: Brain stem functions include most things we do reflexively without thinking, like breathing, swallowing, adjusting our heart rate to our environment, sweating on the face, moving our eyes in unison, keeping our balance and even digesting food. The brain stem also houses the nerves that innervate the structures of the head, including facial muscles. ...Read more
Motor Stip: The cerebral hemispheres have the central fissure. Sort of sepeartes the front part of the brain from the back part of the brain. Anterior or closer to the eyes is a strip of brain that controls almost all motor function and behind the fissue is a strip that controls almost all sensory function. http://thebrain.mcgill.ca/flash/d/d_06/d_06_cr/d_06_cr_mou/d_06_cr_mou.html. ...Read more
What parts of the brain regenerate cells? Also, would the loss in brain cells create loss in intelligence?
What specific Autoimmune diseases attack brain cells and neurons causing a dramatic effect to neurotransmitters,hormones and the function of the brain
Lupus: Systemic Lupus can attack everywhere and lead to the things u asked about. Other considerations are vasculitis syndromes as there is an autoimmune attack on and in blood vessels which can affect neurons indirectly. Myasthenia Gravis also affect the neuromuscular system and affects one of the main neurotransmitter, AcetylCholine. Rheumotologist is specialist to see for autoimmune disorders ...Read more
No: Spinal cord injury affects portions of the body b elow the site of the injury. The brain is not affected, but these injuries are frequently very disturbing and sometimes dangerous. The person suffering from this can be depressed and needing of assistance in many other ways. ...Read moreSee 2 more doctor answers
Integration : Stem cells are pluripotent cells meaning they can be programmed to be anything. The problem or difficulty is the integration and fidelity to a specific site of interest like the spinal cord. There are a number of research going on that someday there would be a cure to the most devastating ailments. ...Read moreSee 1 more doctor answer
Location: This is entirely dependent on the location of the tumor. There will be certain dysfunction by the affected area of the brain where the tumor is. It also is dependent on the side of the brain where the tumor is. ...Read more
Can regular icsc improve the bladder function even partially ? Is electrical stimulation of sacral nerves restore the bladder function
What happens if the upper motor neurons are damaged wouldn't that result in lower motor neuron weakness?
What is the IMPORTANCE of brain stem and frontal lobe regions in EMOTION and EVALUTIONS of research and functions?
Not quite correct: For years, it was felt that nerve cells would not heal. If the cell body dies (apoptosis), it does not resurrect. If the nerve fibre axon is transected, it will not reconnect. But the myelin covering can regenerate, and the brain can employ alternative pathway connections with time. ...Read more
Could MS located in the spine cause symptoms primarily impairing brain function? Like lightheadedness (brain fog) and bad short term memory?
Not related to MS: MS in the spine wouldn't cause any issues with brain function. MS taking place in the brain could cause some issues with lightheadedness but not memory issues, it would have to be a very end-stage degenerative MS to cause such symptoms and even then it would likely be a secondary cause, not a primary. Other things such as vertigo, viral infections, stress, sleep etc could be benign causes of this ...Read more
Since there's deep brain stimulation that stimulate neurons, is there deep brain "inhibition" that inhibits neurons?
Yes: It is interesting that it is called " stimulation", in fact it inhibits the neuron depending upon the degree of stimulation applied. For example the involuntary movement of Parkinson's disease are controlled by "inhibition". Similarly " interstim" is the technique to stimulate to cause inhibition of bladder contractions to cure loss of urinaty control. The entire process is well understood. ...Read more
No: The x ray radiation in a CT has no measurable or known effect on neural tissues. 1) dose is way too low and 2) nerves are relatively radioresistant since the cells don't reproduce very fast, if at all. There is a theoretical risk of cataracts and cancer years later, but this is incredibly small esp. for a single scan and controversial anyway. ...Read moreSee 1 more doctor answer
Great question: Although we don't completely understand this process, the short answer is yes. ...Read more
Bad event: Brain stem hemorrhage is not great, as relatively small area with critical nerves and connections. Hard to control once started, and often pts left with chronic disability. I know this is not good news, but hopefully careful inpatient medical care will lead to survival and rehabilitation measures to restoration. ...Read more
What happens when neurons die by injury!? Specific neurons in the brain , injury to the central nervous system.
In most cases: neurons do not have the ability to regenerate, or have only a limited ability at best. There is significant redundancy and unused capacity with the brain's neural network, so depending on the location and extent of injury, it may be possible to compensate for some degree of neuronal loss due to injury. The damage itself is generally permanent, however. ...Read more
