New research shows that the healthy brain may hold memories which we don’t even remember. 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(核磁共振) imaging.

While participants reviewed the second word list, their brain scans showed more activity in a certain brain area -- the posterior（后部的） median temporal lobe(脑叶) -- 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 goofed 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（前面的）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(决斗) 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.

Marjorie Baer used to joke about her retirement plans．She wasn't married and had no kids, but she didn't intend to be alone—she and all her single friends would move into a fictional home she called Casa de Biddies．Instead, Baer developed terminal brain cancer when she was 52．But just as she'd hoped, her friends and family provided her with love and care to the end．

Ballance was only the first of Baer's friends who became her unofficial caregivers．With her brother Phil Baer from Los Angeles, they worked out a system to watch over their friend and allow her to keep some of the privacy and independence she cherished.

Baer's good friend Ruth Henrich took Baer to doctors' appointments and helped her deal with all the aspects of life —answering machines, TV controls, and even phone numbers．After Henrich sent out an e-mail request, a group of volunteers signed up to ferry Baer back and forth to radiation therapy（放疗）．Others in Baer's circle offered up particular talents: A nurse friend helped Baer figure out how to get what she was due from Social Security and her disability insurance; a lawyer pal helped Baer with her will; a partner who was an accountant took over her bills when she could no longer manage them．"There was this odd sense that the right person always showed up," says Ballance．Their arrangement worked remarkably well．

Unmarried women are one of the fastest-growing groups in America; experts are concerned about how care-giving will be managed for them as they age．If the experience of Baer's friends is a guide, the Internet will play a role．It's already making it possible to create communities of caregivers who may have only one thing in common: the person who needs their help．On personal "care pages" set up through services such as Lotsa Helping Hands, friends and family members can post a list of tasks that need to be done, volunteer to do them, and keep updated on the person's condition．As Baer's cancer progressed, for example, her friends set up a page on Yahoo! where people could sign up to deliver meals or do errands（差事）.

Catherine Fox, one of the friends who were present when Baer died, was deeply affected．"It was so comforting to know that if you're willing to ask for help, the generosity of family and friends can be phenomenal（显著的）．It makes me feel secure and hopeful to know that help is there when you need it．"
