Do You Know About the Stem Cell Therapy for Alzheimer's?

Image
Alzheimer's disease (AD) may be a progressive neurodegenerative disease characterized memory loss and psychological feature impairment. It’s caused by conjugation failure and excessive accumulation of misfolded proteins. To date, most advanced clinical trials on specific AD-related pathways have unsuccessful largely thanks to an oversized variety of neurons lost within the brain of patients with AD. Somatic cell treatment has been thriving in AD animal models. Recent diagnosis studies on somatic cell medical care for AD have verified to be promising. Cell replacement therapies, like human embryonic stem cells or induced pluripotent stem cell–derived neural cells, have the potential to treat patients with AD, and human clinical trials square measure in progress during this regard. AD may be a progressive chronic unwellness that sometimes begins many years before identification. Therefore, a person's brain is severely broken by the time symptoms or signs seem and an oversized v...

Why A Myelinated Neuron Conducts Impulses Faster?

Image
In a myelinated nerve fiber, the conduction of impulse is faster due to the presence of Myelin sheath and node of Ranvier.   As the rate of impulse conduction in a nervous system depends on the diameter of a nerve fiber and the presence or absence of myelin sheath.  Neurons with myelin sheath conduct impulse much faster than those without the presence of myelin. Schwann cells (or oligodendrocytes) are located at various regular intervals along the axons of the neuron. Between the areas of myelin are non-myelinated areas present, called as the nodes of Ranvier. Because fat or lipid molecules (myelin) acts as an insulator, a membrane coated with myelin does not conduct an impulse.  So, in a myelinated neuron, action potentials occur only along with the nodes and, therefore, impulses jump over the areas of myelin, going from node to node in a process called as saltatory conduction. Action potential velocity Brain cells are also called neurons which ...

Is Parkinson’s disease Genetic?

Image
  Parkinson’s disease may be a disorder of the nervous system. It is a progressive condition and causes widespread degeneration within the brain . Approximately 15% of individuals diagnosed with Parkinson’s disease have a known case history of the disorder. Biological interactions that produce to Parkinson’s are complex and not fully understood. Parkinson’s disease often begins with trembling or shaking of a part, especially when at rest. Symptoms are usually more pronounced across one-half the body, with many patients noticing it within the hand. It also can affect arms, legs, feet, and therefore the face. Not all patients experience every symptom within the early stages. Can Parents Pass Parkinson’s Disease to Their Kids? Children don't inherit Parkinson’s disease directly from their parents. However, a parent’s history of the disease makes it more likely that a toddler may experience it afterward in life. it's important to recollect that genes represent a probability...

Athletes and Brain Training

Image
Dawid Kubacki, four-time tournament winner in skiing, has recently started victimisation brain coaching to extend his ability associated probabilities for an Olympic palm. He stated, “I believe what's occurring within the competitors’ heads is that the most vital issue.” He conjointly mentioned, “when you think that of the brain sort of a muscle you simply keep coaching it.” Brain coaching has for a minute been seen as a groundbreaking development once it involves high-level performance, which incorporates commanding sports. a lot of and a lot of uses area unit being found for it daily, and this instance goes to indicate that the advantages of brain exercise area unit limitless. Brain coaching As associate jock In what manner will brain coaching facilitate a brilliant jock to perform better? For the solution, we've to know what quite result the mind has on the body. What we regularly don’t notice is that the mind is a component of the body which the 2 area unit intensely tangl...

Left brain vs right brain

Image
The higher than question may be a extremely widespread question that's hovering at the perimeters of sound neurobiology. There area unit various theories and ideas that exist to elucidate however the correct and left hemispheres of the human brain operate. They conjointly share their deserves, and limitations too. The brain, being AN involved organ, performs heaps of functions. the 2 sides of the brain communicate with each other to perform all very important bodily processes. each the left and therefore the right aspect of the brain look much alike. However, they share some variations, particularly in process data. The past time period has witnessed AN current effort to unravel the mystery behind the two hemispheres and the way precisely they operate. whereas war helped the method on, the traumatic brain injuries it brought created a series of representational experiments unraveling the results of specific brain injuries. Experiments, wherever one 1/2 the brain is anaesthetized wh...

Depression and Its link with COVID 19

Image
  As the COVID-19 pandemic rages on, reports of a tax on global mental health are increasingly reported. This toll has been linked to acute and long-term effects of infection (the latter variably described as long-COVID, long-haul COVID and post-acute COVID). Additionally, worsened mental health has been associated with the detrimental effects of policies designed to limit viral spread. One way these seemingly disparate events connect to similar outcomes may be the link between the immune system and mental health. This may be especially important as it relates to depression, as summarized in a recent review article called "Immunological Interfaces: The COVID-19 Pandemic and Depression ." Long before COVID-19 sunk its teeth into our collective wellbeing, depression was already an international concern affecting upward of 300 million people. And while depression is a psychological state, it’s well understood to have biological underpinnings. There are several molecular pathway...
