November 25, 2016: Various brain regions that once synchronised their activity during memory tasks become smaller and lose cohesion as people age, says a study.

In the study, researchers from Princeton University in New Jersey, US, described a novel method to characterise and compare the brain dynamics of individual people.

The research showed that regardless of whether we were using memory, directing attention, or resting, the number of synchronous groups of connections within our brain was consistent.

However, between different individuals, these numbers vary dramatically.

In fact, during memory specific actions, variations between people are closely linked to age.

Younger participants have only a few large synchronous groups that link nearly the entire brain in coordinated activity, while older participants show progressively more but smaller groups of connections.

In the older group this indicates loss of cohesive brain activity — even in the absence of memory impairment, the authors noted.

“This method elegantly captures important differences between individual brains, which are often complex and difficult to describe,” said Elizabeth Davison from Princeton University.

“The resulting tools show promise for understanding how different brain characteristics are related to behaviour, health, and disease,” Davison added.

For the study, the researchers used functional magnetic resonance imaging (fMRI) to record healthy people’s brain activity during memory tasks, attention tasks, and at rest.

For each person, the fMRI data was recast as a network composed of brain regions and the connections between them.

The scientists then use this network to measure how closely different groups of connections changed together over time.

The study was published in the journal PLOS Computational Biology. (IANS)

A research suggests that if you have practiced yoga for a long time, then you automatically tend to use of your left forebrain. There is more “gray matter” in the left forebrain and therefore, it is a reason, why positive thinking gets affected. Yoga stimulates the left forebrain and helps one to create positive and happy thoughts which in result magnifies your memory and concentration power.

Can Flourishing Islamic State (ISIS) be Stopped in Afghanistan?

The truth about IS and Afghanistan is definitely no picnic

  • Depending on the location, the proliferation of IS has drawn varied resistance from the Afghan military, U.S. air support and ground troops, local militias, Taliban forces and other militant groups
  • Afghan army planes on Wednesday night accidentally air dropped vital supplies of food and water to IS militants in the Darzab district of northern Jouzjan province instead of to their own besieged troops
  • In the Tora Bora area, where IS has made a strong stand in recent days, local villagers and militias joined with Taliban to rout IS

June 25, 2017: The Islamic State group is rapidly expanding in parts of Afghanistan, advancing militarily into areas where it once had a weak presence and strengthening its forces in core regions, according to Afghan and U.S. officials.

Depending on the location, the proliferation of IS has drawn varied resistance from the Afghan military, U.S. air support and ground troops, local militias, Taliban forces and other militant groups.

Attacking IS has become such a priority in the country, that disparate forces sometimes join together in the ad-hoc fight, with Afghan and U.S. forces finding themselves inadvertently supporting the enemy Taliban in battling IS.

Confusion leads to mistakes

All too often, officials say, mistakes are made due to confusion on the ground.

Afghan army planes on Wednesday night accidentally air dropped vital supplies of food and water to IS militants in the Darzab district of northern Jouzjan province instead of to their own besieged troops, provincial police chief, Rahmatullah Turkistani told VOA. The supplies were meant to help Afghan forces that are countering twin attacks by IS and Taliban militants but were used instead by IS.

“It’s not getting better in Afghanistan in terms of IS,” U.S. Chief Pentagon Spokeswoman Dana White told VOA this week. “We have a problem, and we have to defeat them and we have to be focused on that problem.”

Reinforcements for the IS cause reportedly are streaming into isolated areas of the country from far and wide. There are reports of fighters from varied nationalities joining the ranks, including militants from Pakistan, India, Iran, Iraq, Syria, Russia and Central Asian neighbors.

Confusing scenarios

Still, the Islamic State-Khorasan (ISK) as IS is known in Afghanistan remains a fragmented group composed of differing regional forces with different agendas in different parts of the country.

“IS-K is still conducting low-level recruiting and distribution of propaganda in various provinces across Afghanistan, but it does not have the ability or authority to conduct multiple operations across the country,” a recent Pentagon report said. But where it operates, IS is inflicting chaos and casualties and causing confusing scenarios for disparate opponents.

In the Tora Bora area, where IS has made a strong stand in recent days, local villagers and militias joined with Taliban to rout IS. IS regained ground after a few days, leading to U.S. military air attacks on IS positions in conjunction with Afghan intelligence instructions and army operations.

IS fighters reportedly have fled from mountain caves of Tora Bora, where al-Qaida’s leader Osama bin Laden hid from U.S. attack in 2001.

Families displaced

IS fighters were also reportedly advancing in neighboring Khogyani district, displacing hundreds of families, according to district officials. It is one of several areas in Nangarhar province, near the Pakistani border, where IS has been active for over two years.

Fierce clashes in the Chaparhar district of Nangarhar last month left 21 Taliban fighters and seven IS militants dead, according to a provincial spokesman. At least three civilians who were caught in the crossfire were killed and five others wounded.

“IS has overpowered Taliban in some parts of Nangarhar because the Taliban dispatched its elite commando force called Sara Qeta (Red Brigade) to other parts of the country, including some northern provinces to contain the growing influence of IS there,” Wahid Muzhda, a Taliban expert in Kabul, told VOA.

Recruiting unemployed youths

IS has also expanded in neighboring Kunar province, where, according to provincial police chief, it has a presence in at least eight districts and runs a training base, where foreign members of IS, train new recruits.

Hundreds of miles from Nangarhar, IS is attempting to establish a persistent presence in several northern provinces where it has found a fertile ground for attracting militants and recruiting unemployed youths, mostly between the age of 13 and 20.

IS has been able to draw its members from the Pakistani Taliban fighters, former Afghan Taliban, and other militants who “believe that associating with or pledging allegiance” to IS will further their interests, according to the Pentagon report.

Hundreds of militants have joined IS ranks in northern Jouzjan and Sar-e-Pul province where local militant commanders lead IS-affiliate groups in several districts.

Darzab district

Qari Hekmat, an ethnic Uzbek and former Taliban militant who joined IS a year ago, claims to have up to 500 members, including around 50 Uzbek nationals who are affiliated with the Islamic Movement of Uzbekistan (IMU) — previously associated with al-Qaida and Taliban in Afghanistan.

IS and Taliban are reportedly fighting over the control of Darzab district in Jouzjan which they stormed this week from two different directions and besieged scores of government forces. The Taliban has reportedly captured the center of the district while IS militants control the city outskirts.

Afghanistan faces a continuing threat from as many as 20 insurgent and terrorist networks present or operating in the Afghanistan-Pakistan region, including IS, the Pentagon said.

“In areas where the government has limited influence and control, IS attempts to emerge and expand there,” Ateequllah Amarkhail, an analysts and former Army general in Kabul told VOA.

Hit-and-hide strategy

IS has also claimed responsibility for several recent attacks in urban areas, however, with a hit-and-hide strategy that is proving effective. And it is engaging too in more skirmishes with U.S. forces that initially were sent to the country to help Afghan forces halt the spread of Taliban.

Three American service members based in eastern Afghanistan were killed in April during operations targeting IS militants, according to the Pentagon.

“ISIS-K remains a threat to Afghan and regional security, a threat to U.S. and coalition forces, and it retains the ability to conduct high-profile attacks in urban centers,” the Pentagon said. (VOA)
