How memories form, fade, and persist over time

Wednesday, January 28th, 2009

What was the name of that guy with that stuff in that place with those things? Don’t you remember?

Scientists have found mechanisms for how the brain creates short-term and long-term memories.

Scientists have found mechanisms for how the brain creates short-term and long-term memories.

We all suffer occasional lapses in memory. Some people suffer severe neurological conditions, such as Alzheimer’s, that rob them of their ability to form memories or remember recent events.

Three new studies shed light on the way the brain forms, stores and retrieves memories. Experts say they could have implications for people with certain mental disorders.

When did it happen?

Newly born brain cells, thousands of which are generated each day, help “time stamp” memories, according to a computer simulation by scientists at the Salk Institute for Biological Studies in La Jolla, California, and the University of Queensland in Australia. The research was published in the journal Neuron.

These cells do not record an exact, absolute date — such as January 28, 2009 — but instead encode memories that occur around the same time similarly. In this way, the mind knows whether a memory happened before, after or alongside something else.

Neuroscientists believe that if the same neurons are active during two events, a memory linking the two may be formed. Complete article on CNN below…

The Arts Come Marching In Again

Once alight with bulbs that spelled out “Armstrong,” the large steel archway above North Rampart Street, across from the venerable Donna’s Bar & Grill, was dark much of the past decade, largely rusted. Beneath it, the main gate to a park named for trumpeter Louis Armstrong had been padlocked for more than three years, save for the occasional special event. Just inside, Congo Square — where two centuries ago enslaved Africans and free people of color spent Sundays dancing and drumming to the bamboula rhythm, seeding the pulse of New Orleans jazz — had been effectively off limits. The adjacent Mahalia Jackson Theater of the Performing Arts, home to opera and ballet performances for more than 30 years, sat empty and in need of repair after taking on 14 feet of water in 2005.

It would be hard to find a more potent symbol of the tenuous state of musical life and cultural history in a city largely defined by both. But earlier this month, shortly after dusk, Mayor C. Ray Nagin flipped a switch — just a prop, it turned out, for dramatic effect — and on went the lights of the arch and the park’s streetlamps. As the Original Pin Stripe Band played “Bourbon Street Parade,” a small mock second-line parade wound its way around a bronze statue of Armstrong and over to a sparkling Mahalia Jackson Theater for a free concert, the first in a series of events spanning 10 days and a broad range of performing arts.

“The cultural arts of New Orleans are back bigger, better and stronger than ever before,” Mayor Nagin had said at an afternoon press conference. “This is the start of what I predict will be a year of unprecedented construction in the city.”

William Chrisman, the city’s capital-projects administrator, estimated the theater renovation’s cost at $22 million, with the park restoration adding an additional $5 million. FEMA, which initially denied funding, has pledged to reimburse $9 million. John Quirk, who oversees the federally owned National Jazz Historical Park — three leased acres within Armstrong Park — hopes to complete his renovations late this year.

“Thus when the ambitious man whose watchword was ‘Either Caesar or nothing’ does not become Caesar, he is in despair thereat. But this signifies something else, namely, that precisely because he did not become Caesar he now cannot endure to be himself. So properly he is not in despair over the fact that he did […]

“You may perhaps beat science into a person, but the ethical has to be beaten out of them, as with the corporal who, on seeing the makings of a soldier in a country lad, could say, ‘I’ll manage to beat a soldier out of him,’ whereas when it comes to imparting the little book on […]

“So for the first thing, the knight will have power to concentrate the whole content of life and the whole significance of reality into a single wish. If a man lacks this concentration, this intensity, if his soul from the beginning is dispersed in the multifarious, he never comes to the point of making the […]

“This was the commandment, ‘Thou shalt love thy neighbor as thyself,’ but when the commandment is rightly understood it also says the converse, ‘Thou shalt love thyself in the right way.’ If anyone, therefore, will not learn from Christianity to love himself in the right way, then neither can he love his neighbor; he may […]

Save me, O God, from ever being completely sure; keep me unsure until the end so that then, if I receive eternal blessedness, I might be completely sure that I have it by grace! It is empty shadowboxing to give assurances that one believes it is by grace — and then to be completely sure. […]

“How poor a thing is language compared with the unmeaning yet significant combination of clangorous sounds in a battle or at a banquet, which not even a theatrical rendering can reproduce, and for which language possess but a few words!
