Brain generates pessimistic mood?

Published

New York, Aug 12 : Scientists have identified a brain region that could generate pessimistic moods in disorders such as anxiety or depression that leads people to focus more on the possible downside than the potential benefit in a stressful situation.

In a study tested on animals, researchers at the Massachusetts Institute of Technology (MIT) have found that stimulating caudate nucleus — a brain region linked to emotional decision-making –induced animals to make negative decisions.

The caudate nucleus, has within it regions that are connected with the limbic system, which regulates mood, and sends input to motor areas of the brain as well as dopamine-producing regions.

The study showed that the animals gave far more weight to the anticipated drawback of a situation than its benefit, compared to when the region was not stimulated.

This pessimistic decision-making could continue through the day after the original stimulation.

“We feel we were seeing a proxy for anxiety, or depression, or some mix of the two,” said Ann Graybiel, a professor at the MIT.

In the study, which appeared in the journal Neuron, the team wanted to see if they could reproduce an effect that is often seen in people with depression, anxiety, or obsessive-compulsive disorder.

The team stimulated the caudate nucleus with a small electrical current as animals were offered a reward (juice) paired with an unpleasant stimulus (a puff of air to the face).

The results showed that the cost-benefit calculation became skewed, and the animals began to avoid combinations that they previously would have accepted.

This continued even after the stimulation ended, and could also be seen the following day, after which point it gradually disappeared.

This result suggests that the animals began to devalue the reward that they previously wanted, and focused more on the cost of the aversive stimulus.

“This state we’ve mimicked has an overestimation of cost relative to benefit,” Graybiel noted.

The researchers also found that brainwave activity in the caudate nucleus was altered when decision-making patterns changed.

“There must be many circuits involved,” she said.

“But apparently we are so delicately balanced that just throwing the system off a little bit can rapidly change behaviour.”

Virgin brows, glittery lids: Beauty trends to rule in 2019

Eye Makeup

New Delhi, Jan 23: Glittery lids, virgin brows and bronzer are in this year, say experts.

Here we have shared some of the beauty trends that you can follow:

** Glitter means instant glam-up. However, you don’t need to swim in it. A little is perfect. Take a very tiny amount of gold or silver and lightly dust it on the inner corner of your eyes. A hint of glitter peeping from the inner corner of your eyelids is perfect to lend that unmistakable spark to your look. In case you want to get into the diva mood, cover your lids with chunky gold glitter. Always remember that a glitter trend never goes away.

** Instead of applying an overall eyeshadow, go for fading traces of colour on both upper and lower lids. Use different but complementing colours for upper and lower lids. Finish off with a liner and mascara and you are done.

** It’s time to ‘unfollow’ the perfectly shaped eyebrows and follow real and raw brows. While tweezers are kept aside, the eyebrows are groomed with the help of eyebrow brush. If the idea of bushy brows is too daunting for you, then you can shape your brows in a natural arch, instead of a total clean up.

** While bronzer makes its way back, heavy contouring is shown the exit door. Skip framing the face to perfection. Instead, take a large fluffy brush, and put the bronzer along the temple, cheekbones and jawline. And you are done. Keep the skin clean and luminous with a high-definition foundation.

Here are few more suggestions by the experts:

** Last year was the year of the hot red shade. This year will be all about subtle and dark tones of brown matte and gloss. Be it eyes, lips or cheeks highlighting, brown would be seen everywhere. Even the hair colour in brown would be more viral.

** Nude is the new chic: Keep your make-up natural and minimal to give it a fresh look. Speaking of nude make-up, women have found a new companion. Base oils. From a variety of oils ranging from rose to gold, women are loving this new trend. Sandalwood oil has always symbolised purity and its fragrance has stood the test of time.

** This year again, the winged eyeliner will be in trend.

** Smokey eyes are gorgeous as ever, but can be too bold for some. As bridal make-up moves into its understated glam phase, it is time to welcome the blurred eyeliner. With the flexibility of playing with colours and intensity that this smudged look allows, it manages to complement just about every age and style and is perfect for a bridal glam look.

In stress? Remember your romantic partner and keep BP down

blood-pressure

Having a romantic partner present — even in your mind — can help you keep blood pressure down in daily stressful situations, say researchers.

When faced with a stressful situation, thinking about your romantic partner may help keep blood pressure under control just as effectively as actually having your significant other in the room with you, according to a study by University of Arizona psychologists.

“This suggests that one way being in a romantic relationship might support people’s health is through allowing people to better cope with stress and lower levels of cardiovascular reactivity to stress across the day,” said psychology doctoral student Kyle Bourassa.

“It appears that thinking of your partner as a source of support can be just as powerful as actually having them present,” Bourassa added.

For the study, published in the journal Psychophysiology, 102 participants were asked to complete a stressful task — submerging one foot into 3 inches of cold water ranging from 38 to 40 degrees Fahrenheit.

Researchers measured participants’ blood pressure, heart rate and heart rate variability before, during and after the task.

The participants, all of whom were in committed romantic relationships, either had their significant other sitting quietly in the room with them during the task or they were instructed to think about their romantic partner as a source of support during the task. In third scenario, they were instructed to think about their day during the task.

The effect on blood pressure reactivity was just as powerful whether the partner was physically present or merely conjured mentally.

“The findings may help explain, in part, why high-quality romantic relationships are consistently associated with positive health outcomes in the scientific literature,” said Bourassa.

If replicated, the findings could have implications for those facing everyday stressful situations, the researchers added.

Myntra taps 9,000 kirana stores in 50 cities to boost last-mile delivery

New Delhi, Jan 22 : Flipkart-owned ecommerce platform Myntra that saw 80 per cent revenue fall in FY2018 has doubled down on last-mile delivery, tapping into over 9,000 kirana stores across 50 cities to fast deliver packages.

Today, nearly 60 per cent of all Myntra’s product pick-ups and deliveries happen through its “Kirana Delivery Programme” — helping the company reduce delivery costs, the company told IANS on Tuesday.

“Myntra’s ‘Kirana Delivery Programme’ is a successful model introduced by the company to accelerate order delivery in the most efficient way possible, while ensuring we provide a good partnership opportunity to our kirana partners,” a company spokesperson told IANS.

“We will continue to innovate, expand and hope to register more kirana partners in the future as well,” the spokesperson added.

The “Kirana Delivery Programme” is an ingenious model introduced by the company to accelerate order delivery, while creating a platform for kirana stores to have an additional source of income.

“A mutually beneficial model, it has helped Myntra achieve greater consumer satisfaction and is enhancing the standard of living of the owners of several ‘mom & pop’ stores across the country,” said the company.

Several tailors and beauty parlour owners, among others, have also signed up with Myntra for the programme.

The online fashion retailer narrowed its consolidated losses to Rs 178.7 crore for 2017-18, compared with a loss of Rs 655.8 crore in the previous fiscal.

According to business intelligence platform Tofler, the company saw its income growing nearly threefold to Rs 427.4 crore in 2017-18 as against Rs 155.6 crore in the previous financial year.

Ananth Narayanan, Chief Executive of e-tail portals Myntra and Jabong, stepped down from the post on January 14 “to pursue external opportunities”.

The 11-year-old Flipkart Group, owned by US retail giant Walmart, includes e-tail sites Flipkart, Myntra, Jabong and digital payment platform PhonePe.

In May last year, Walmart bought a 77 per cent equity stake in the company for a whopping $16 billion.
