Stimulating the brain with gentle electric currents during sleep boosts memory, German scientists reported Sunday in the online version of the journal Nature. When they applied several currents that mimic natural, slow-oscillating brain waves in sleep, they enhanced the memory of medical students who had done a word-learning task by 8%. The students did not feel any sensation from the currents to the frontal cortex of the brain or any adverse side effects.

Spilt Milk A Novel Chico Buarque Translated from the Portuguese by Alison Entrekin Grove Press: 178 pp., $23 Eulálio d'Assumpção is on his deathbed. A century old, born into the Brazilian aristocracy, he has watched his world change, or crumble, and still he lingers. "As the future narrows," he tells us early in Chico Buarque's deft and moving "Spilt Milk," "younger people have to pile up any which way in some corner of my mind. For the past, however, I have an increasingly spacious drawing room.

The hippocampus and the medical temporal lobes are critical for a healthy memory. They are involved in the function of the declarative memory, one of two major types of remembering. All declarative memory is conscious, meaning that a person is aware of its retrieval. It includes such tasks as the ability to briefly hold facts and then discard them or to recall episodes from earlier years. The other main type of memory is nondeclarative, or the unconscious retrieval of information.

Brain scans confirm what many coffee drinkers already know: Caffeine perks them up. The caffeine found in coffee, tea, soft drinks and chocolate stimulates areas of the brain that govern short-term memory and attention, Austrian researchers said Wednesday at the annual meeting of the Radiological Society of North America.

Just as the smell of watermelon might trigger a recollection of a childhood picnic, the release of odors during deep sleep can help people form new memories, a new study found. Students who received bursts of rose-scented air while they played a memory game and then received similar bursts of smell during deep sleep outperformed others by 15% when they replicated the exercise the following day, according to a study published last week in the journal Science.

Steady exposure to the electromagnetic radiation given off by cellphones during use may disrupt fetal development, disturb memory and weaken the barrier that protects the brain from environmental toxins, says a welter of new research being presented this week in Istanbul, Turkey. The authors of the studies, published in the past two years, highly preliminary and conducted on rabbits, mice and rats, suggested that the non-ionizing radiation emitted by cellphones and the base stations that broadcast cellphone signals may fundamentally damage cells by means other than the heat that they generate.

Rejecting testimony influenced by a so-called truth serum, a state appeals court has ordered the dismissal of a woman's repressed-memory suit against her father, who lost his job and his marriage after she accused him of rape. Holly Ramona's proposed testimony against her father, Gary, was inadmissible because it was affected by the drug sodium amytal, the 2nd District Court of Appeal said Tuesday.

For those with minor memory problems, most often associated with aging, Dr. Arnold Starr, director of the Memory Disorders Clinic at UC Irvine, outlines a set of tricks that usually help: * Train yourself to pay attention to certain details that previously required little thought, such as street names, people's names and directions. * Get in the habit of making word associations. For example, to remember the street name Equestrian Lane, think of a horse.

Two decades ago, they numbered in the hundreds. On Sunday, there were just a few dozen. But when Los Angeles Mayor Antonio Villaraigosa asked them to stand and be recognized, the Holocaust survivors in attendance for the annual Holocaust Remembrance Day at Pan Pacific Park in Los Angeles were met with a standing ovation. "We ask you to stand up because of your courage, your perseverance and your memories," Villaraigosa said. "We honor you today because those memories of yours will make sure that this will never, ever happen again."

Scientists have shown for the first time that brain activity during sleep strengthens the ability to learn and remember -- at least in birds. But they insist the finding has meaning for humans too. Earlier human studies had shown that a good night's sleep in adults improved memory.
