Scientists are one step closer to understanding how to erase painful fear memories by successfully erasing them in a small group of people, according to a study published Thursday in the journal Science. The intervention requires no drug, acting through behavioral intervention alone. The new report follows a series of studies in which researchers have made significant headway in understanding where such fear memories are processed in the brain, and how to erase them for good. Much of this research has been carried out in rodents, where researchers have shown that it is possible to erase fear memories by both pharmacological and behavioral means.

A concert cellist whose memory was virtually wiped out by a brain infection may no longer remember the names of the composers whose work he once played before admiring audiences. But he can remember and recognize virtually every note of their compositions, and even more remarkably, can learn and commit to memory new pieces of music he did not know before a raging case of herpes encephalitis robbed him of his ability to recognize most of his family, recall details of his homeland or remember details of his own life before his illness.

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.

Thanks for printing "The Man Who Remembered Nothing" (by Gordon Steel, as told to Dana Harris, Feb. 3). It is a touching story and beautifully written. Surely we can all learn from Steel's determination to overcome persistent memory loss and develop a career in a field where memory is everything--and from the kind and useful assistance of his friend Jerry Edelstein and the loyal support of his family.

For many years, doctors have been trying to harness the memory-enhancing powers of nicotine without exposing people to the carcinogenic chemicals in cigarette smoke. A nicotine patch could be the answer. Several studies have shown that nicotine can improve attentiveness among patients with attention deficit disorders, schizophrenia, Parkinson's disease and mild to moderate Alzheimer's.

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.

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.

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.
