How the brain weaves a memory
11-08-2006 · EurekAlert!Memories of events comprise many components -- including sights, sounds, smells and tastes. Somehow the many features of an episodic memory are woven together into a coherent whole, and researchers have had little understanding of how this binding takes place as the memories are processed by the brain's memory center, the hippocampus. A central question has been whether the hippocampus receives an "episodic packet," or a collection of perceptual strands that it must integrate into a memory.

- Speak, memory: Research challenges theory of memory storage
11-14-2006 · EurekAlert!
During sleep, freshly minted memories move from the hippocampus, part of the "old" brain, to the neocortex, or "new" brain, for long-term storage. This has been the reigning theory for decades. Brown University research provides the strongest proof yet of this interaction between the old and new brains -- and offers surprising evidence that challenges critical details of this theory of learning and memory. Results appear in Nature Neuroscience.

- Antidepressants stimulate new nerve cells in adult monkeys, may have implications for humans
05-04-2007 · EurekAlert!
In adult monkeys, an antidepressant treatment has induced new nerve cell growth in the hippocampus, a brain area responsible for learning and memory. A similar process may occur in humans, the research suggests, and may help explain the effectiveness of antidepressant treatments.

- New protein synthesis not essential to memory formation
07-26-2007 · EurekAlert!
New research from the University of Illinois challenges the premise that the brain must build new proteins in response to an experience for that experience to be recorded in long-term memory.The findings, published in the Proceedings of the National Academy of Sciences, could alter basic assumptions about the role of protein synthesis in memory formation.

- Brain network related to intelligence identified
09-11-2007 · EurekAlert!
Researchers have uncovered evidence of a distinct neurobiology of human intelligence. This Parieto-Frontal Integration Theory identifies a network related to intelligence, one primarily involving areas in the frontal and the parietal lobes. The data suggest that some of the brain areas related to intelligence are the same areas related to attention, memory and language. This possible integration of cognitive functions suggests that intelligence levels might be based on how efficient the frontal-parietal networks process information.

- How brain injury leads to seizures, memory problems
10-18-2006 · EurekAlert!
Every 23 seconds, an American suffers a traumatic brain injury. In a finding that may provide a scientific basis for eventual treatment, neurology researchers have shown that traumatic brain injury (TBI) reduces the level of a protein that helps keep brain activity in balance. The resulting abnormal activity, in turn, is thought to be an underlying reason for seizures and memory defects experienced by people who have suffered a TBI.

- Neuroscientist records surprising brain 'dialogue' during sleep
03-05-2007 · EurekAlert!
A Brown University-led research team has, for the first time, recorded activity inside the cells of the hippocampus while simultaneously measuring activity in the neocortex. Recordings from these two brain regions -- seats of memory creation and storage -- revealed a surprisingly complex pattern of activity. These findings, in the Proceedings of the National Academy of Sciences, are part of a growing body of evidence that challenges traditional theories of the role of sleep in learning and memory.

If you spotted an anaconda poised to strike, the signal to pay attention would originate in a different part of your brain than if you gazed at an anaconda in the zoo, neuroscientists at MIT's Picower Institute for Learning and Memory report.

- Brain networks strengthened by closing ion channels
04-20-2007 · EurekAlert!
Yale School of Medicine and University of Crete School of Medicine researchers report in Cell April 20 the first evidence of a molecular mechanism that dynamically alters the strength of higher brain network connections involved in working memory. This discovery may help the development of drug therapies for the cognitive deficits of normal aging, and for cognitive changes in schizophrenia, bipolar disorder, or attention deficit hyperactivity disorder (ADHD).
