In The Journal of Neuroscience, experts report that the brain might hold more memories than people realize, but that restoring those memories can be tricky. Memory Check First, participants saw a list of 120 real words mixed with 80 nonsense words. Next, they saw another word list and tried to remember which words had been on the first list. Meanwhile, their brains were scanned with functional magnetic resonance imaging. While participants reviewed the second word list, their brain scans showed more activity in a certain brain area -- the posterior median temporal lobe -- when they saw words that had been on the first word list. But participants didn't always remember that they'd seen those words before. Sometimes, they _ and said they hadn't seen those words before. In other words, the posterior median temporal lobe was more sensitive to memory than participants' consciousness, the researchers note. "Album"of Memories Another part of the median temporal lobe also attracted the scientists' attention. The anterior median temporal lobe showed more activity when participants thought they were seeing a new word, the study shows. So, why did participants sometimes mess up their memory recall? It might be that two parts of their brain -- the posterior and anterior median temporal lobes -- might be dueling for the upper hand in deciding what actually happened in the past, the study notes. In other words, memories might have a photo album in the brain, but sometimes we forget what's on all of the photo album's pages. Question: What did the experts discover when the participants saw the words on the first word list appear on the second word list? - The instrument worked faster. - The participants were more conscious. - The posterior median temporal lobe was more active. - The anterior median temporal lobe was more active.
The posterior median temporal lobe was more active.

Unlike package tours, backpacking is a struggle, full of discovery and chance connections. It is about focusing on something different from our own lives and losing ourselves in a new world, if only for a moment. Well, that's what backpacking Europe is supposed to do. That's what it used to do before modern communications, social media, and commercial hostelling . Older Canadians would not recognize the Europe that they backpacked in the 1960s, 1970s and even the 1980s. Far from a rough adventure into foreign cultures, the European experience has been _ in part by today's technology. A few years ago, I took my then 60-year-old father on a backpacking trip across part of Europe and Turkey. As he is an experienced traveler and someone who possesses a strong sense of adventure, I decided that we'd travel on a budget, staying in hostel dorms. For him, backpacking through Europe in 1969 was about independence and struggle. But two things surprised him at the end of our journey. First was how technology-based backpacking had become: Young people were so directly connected to home that they were hardly away in any meaningful sense. Second, the lack of connections we made with locals. Instead of making us feel closer to a place, he found commercial hostelling actually made us more alienated . But there was some room for hope. While technology takes our attention away from the beauty and history before us, there were also ways in which it helped us to connect with our surroundings. Websites like Airbnb have made it easier to stay with enthusiastic locals. Couch Surfing helps organize meet-ups between locals and travelers. The online marketplace Dopios offers a chance to meet locals through enjoyable experiences like a personalized city tour. Backpacking can never be the way it was for our parents' generation. But doing a little study of history and culture before leaving, and bravely getting rid of any electronic devices while... Question: What's the author's attitude towards technology? - Negative. - Objective. - Uncertain. - Uninterested.
Objective.

She had broken actually every long bone in her body, along with her pelvis, jaw, and cheekbones. He was terrified his bride would bleed to death. Stephen and Shelli had married just six months before near their home in South Jordan, Utah. They were in Hawaii on a family vacation with two of their sons. The family had rented electric motors and headed towards a nature preserve near Waikiki. But Shelli had fallen behind and the family turned back to make sure she was okay. Shelli lost so much blood that her heart couldn't function properly and she went into shock at the hospital. Physicians were able to make her come to herself. On the first and second days there, she lived through half a dozen operations. On day three, the worst of Stephen's fears came true. Shelli didn't wake. She had shown heart failure and lung failure. "I thought every heartbeat would be her last," Stephen says. As days passed with no change, one doctor gently asked if it was time to let Shelli go. An MRI showed her brain didn't have much chance of supporting life. Stephen couldn't bear the thought of trapping his wife's beautiful spirit in a body that would never work. If he kept her alive, what kind of life would she have ? He called family, religious leaders, and physician friends in Utah for guidance. And he decided there still was a chance. The family moved Shelli to a Utah hospital closer to home. In the next few weeks she started opening her eyes, but it wasn't entirely clear how conscious she was. Nearly seven weeks after the accident, Stephen was joking with his sister in the hospital room when he saw Shelli smile, a big toothy grin. "Did you understand that?" he asked. She smiled again. Stephen fell to his knees in thanks. Shelli's recovery has been slow but steady. Initially, she couldn't remember much of the previous months, including her own wedding. Shelli has endured 17 operations so far and may require...
