Areas that Control Anxiety

New optogenetic research on mice from Karl Deisseroth’s lab at Stanford has recognized two imperative pathways identified with anxiety control in the cerebrum. The lab has spearheaded a method that hereditarily alters particular cells to end up more dynamic when light is presented. Along these lines the scientists have the capacity pinpoint which cells are included with a particular cerebrum action. From National Science Foundation’s press discharge, coordinated hereditary controls cause particular neurons to collect a light-actuated protein typically found in green growth and microscopic organisms. At the point when activated by specific wavelengths of light, these proteins permit specialists to expand or diminishing neuronal movement in the mind and watch the consequences for rat models in an investigation. Utilizing optogenetic control of different amygdala pathways, Deisseroth and associates inspected how mouse conduct was influenced. Since mice show uneasiness related practices in open spaces, they measured changes in tension by breaking down the amount of time mice used investigating the focal point of an open field, or investigating the length of a stage without dividers. While optogenetics has been utilized to study amygdala work in behaviorally-molded alarm. It is also the first occasion when it has been utilized to study nervousness. “Fear and anxiety¬†are distinctive,” Deisseroth clarified. “Fear is a response to an immediate threat, but anxiety is a heightened state of apprehension with no immediate threat. They share the same outputs, for example physical manifestations such as increased heart rate, but their controls are very different.”

Could their rollercoaster ride be over?

med2.jpgHave you ever tried riding a rollercoaster? You just canít stop yelling at the top of your lungs because of its challenging ups and downs. One moment youíre up there, the next minute youíve almost kissed the ground. It may be an adrenaline-pumping experience for many, but for bipolar patients, living life on a constant rollercoaster ride is no fun at all.

People suffering from a bipolar disorder or the so-called manic depression are living life on an emotional rollercoaster. They can be extremely happy for one moment then for the next few hours they can be dreadfully depressed. There seems to be no in between.

Itís sad to know that there is no cure for bipolar disorder but good thing there is a way to treat it effectively. Doctors treating patients with bipolar disorder have been using lithium carbonate for 50 years now however, itís found not effective for everyone. To solve this problem, doctors
started giving the patients anti-depressant and anti-psychotic drugs
.

For patients with bipolar disorder, life is never easy for it is a series of extremes. But with the advancing medical technologies we can just hope that soon the rollercoaster ride for them will be completely over.

Diet has a very important role in man’s struggle against diseases and disability.
Latest research finds that eating enough quantities of nutritious diets in along with proper exercise are the major contributing factors to one’s physical fitness and health. The research was conducted to American people. It showed that one out of every three Americans is obese. These individuals who are obese are at greater risk for additional diseases, since obesity leads to other health problems, such as diabetes. A team of researchers has examined the effect of exercise on fat accumulation in a new study involving five obese women. In one session the women overate and did not exercise; in a follow-on session they overate and did exercise. The researchers found out that  the body’s fat-burning oxidation rate was reduced after one day of overeating; conversely, just one session of exercise increased the rate of fat-burning oxidation; and exercise increased the amount of fat that would eventually be stored in the muscle.
