Lhx2 – a new found protein in the glial cells of brain was determined as prime contributor to the health of nerve cells. Lhx2 plays a dual role in the central nervous system by fluctuating its activity levels. For instance, when the activity level of the protein is low, the support cells of brain get triggered enough to hike the protective power of central nervous system. When the activity level of Lhx2 protein is high it utilizes the power of the support cells for protecting nerve cells. the dual mode activity of this protein would be most likely utilized in handling the nervous damage situations like blow to the head, or brain diseases like Alzheimer’s or Parkinson’s disease.
Be it blueberries, blackberries or strawberries – the one thing you could count on berries for is a nice memory. Berries intercept the deteriorating brain changes that tend to set into the human body with age. Berries are enriched with essential antioxidant compounds that protect the brain cells from the deleterious effects of freely rolling free radicals. Free radicals tend to cause damage to the neurons and therefore retard their capacity to transmit motor signals.
Recent studies based on the effect of stress on brain lobes suggest that frequent exposure to stress inducing factors can possibly lead to anxiety disorders and depression. Corticotropin-releasing hormone is an essential endocrinal secretion that is released by the neurons of the brain when a stressful situation is encountered by a person. Corticotropin-releasing hormone (CRH) is considered as a major controller of the “fight-or-flight” response to stress which means that it determines the concluding outcome of a stressful situation.
MDD (Major depressive disorder) is a mental illness that is prominently marked by signs of gloominess and lost concentration. The presence of these signs has been sourced to the high-end connectivity between the dorsal caudate and prefrontal cortex regions of brain. These are the crucial regions of brain that regulate the emotional behavior of humans. A high-end connectivity between the dorsal caudate and prefrontal cortex regions of brain represses the working memory and upholds the negative thoughts in brain.
Meditation can help people in coping with many issues of health and many unhealthy habits like smoking. Nevertheless, the recent brain imaging studies performed at the Yale University reveal that meditation can actually turn off the sections of brain that trigger daydreaming, anxiety, and schizophrenia. This section of brain is known as ‘default mode network’ and comprises of medial prefrontal and posterior cingulate cortex. The fMRI scans performed on people who meditate on a regular basis.
Intensive research performed at Albert Einstein College of Medicine of Yeshiva University has paved way for a new finding that brains might actually be capable of regulating blood sugar levels of the body. Brain is the prime body organ that demands maximum supply of glucose. The hypothalamus region of brain is sensitive to the stimulation of potassium channels and therefore signals the liver cells for dampening the production of glucose. Many brain medications like diazoxide tend to activate the potassium channels and therefore regulate the production of glucose through liver.
Sleep apnoea is a condition that can majorly lower the level of oxygen in the body while it is in a subconscious state. Lack of oxygen supply to the brain cells over a long term can lead to cognitive impairment and dementia. The detrimental effect of sleep apnoea on brain can be noted over a time span of 4-5 years. These changes were found with a higher frequency in women. Researchers suggest that oxygen therapy can be a suitable solution for putting an end to this problem.
Though the etiological factors of many neurodegenerative disorders are still a mystery, researchers have encountered a common findings in all the neurologically affected patients. These common findings were the presence of DNA-attacking oxygen molecule variant and high levels of iron and copper in brain. Abnormally high levels of iron and copper in brain might deteriorate mental health by promoting the production of DNA-attacking oxygen molecule and interfering with the repair process of DNA. The commonest neurodegenerative disorders that are caused by these debilitating changes are Alzheimer’s and Parkinson’s disease.
Be it plastic or medicinal form of surgery that might be implicated for kids, there are chances of them to develop some sort of brain damage during the surgical procedures because of the anaesthetics that are used. The developmental form of brain damage might not get prominently exhibited in the childhood stage but it does get exhibited in the form of developmental and behavioural disorders at a later stage in life. It seems that the molecules of the anaesthetics penetrate the brain in its developing stage and get incorporated into them permanently.
Depression is like an epidemic that is fastly spreading in today’s fast-paced world. However, the recent revelation about the long used anaesthetic drug – Ketamine has brought hope in lives of many people who suffer with some or the other depression disorder. Ketamine redevelops the connection that may have got lost due to stress between neurons or brain cells and brain and therefore nullifies the psychotic symptoms in a depressed subject to a major extent.
