Title: Moderate drinking can improve memory
Hitting the bottle to help drown out memories you'd rather forget may in fact etch them more deeply into your consciousness, a new study has found.
And having one or two glasses of wine a day may increase your ability to remember, and even help with Alzheimer sufferers.
The study at Auckland University was undertaken by Dr Maggie Kalev and Professor Matthew During.
The two researchers found moderate levels of alcohol consumption, equivalent to one or two glasses of wine a day, could enhance memory. wow gold
In contrast, high levels of alcohol decreased the ability of new brain cells to develop and mature.
"Low levels of alcohol promoted neutral memories, such as remembering objects," said Dr Kalev.
"However, contrary to popular belief, we also found that excessive levels of alcohol enhanced memories of highly emotional stimuli, meaning the concept of `drinking to forget' is unlikely to be true.
"Our work suggests that heavy drinking actually reinforces negative memories."
The study also identified the way low doses of alcohol improved memory.
Dr Kalev said a "very important" brain receptor, called an *A receptor, appeared to be necessary for the process.
Testing done on rats showed if they did not have enough *A receptors, their memory did not improve when given low alcohol doses.
However, rats which did show high numbers of *A receptors exhibited memory improvement when given small amounts of alcohol. wow gold
"Pathways by which memory is laid down are unclear, but *A receptor is critical in this process," Dr Kalev said.
"Building on this knowledge may help in the treatment of memory disorders, such as Alzheimer's disease and other dementias."
The results of the study are published in Journal of Neuroscience. wow gold kaufen

'But is it not possible,' I suggested, 'that although the letter may be in possession of the minister, as it unquestionably is, he may have concealed it elsewhere than upon his own premises?'
'This is barely possible,' said Dupin. 'The present peculiar condition of affairs at court, and especially of those intrigues in which D- is known to be involved, would render the instant availability of the document - its susceptibility of being produced at a moment's notice - a point of nearly equal importance with its possession.'
'Its susceptibility of being produced?' said I.
'That is to say, of being destroyed,' said Dupin.
'True,' I observed; 'the paper is clearly then upon the premises. As for its being upon the person of the minister, we may consider that as out of the question.'
'Entirely,' said the Prefect. 'He has been twice waylaid, as if by footpads, and his person rigorously searched under my own inspection.'
'You might have spared yourself this trouble,' said Dupin. 'D-, I presume, is not altogether a fool, and if not, must have anticipated these waylaying, as a matter of course.'
'Not altogether a fool,' said G., 'but then he's a poet, which I take to be only one remove from a fool.'World of Warcraft Gold wow gold
'True,' said Dupin, after a long and thoughtful whiff from his meerschaum, 'although I have been guilty of certain doggerel myself.'
'Suppose you detail,' said I, 'the particulars of your search.'
'Why the fact is, we took our time, and we searched every where. I have had long experience in these affairs. I took the entire building, room by room; devoting the nights of a while week to each. We examined, first, the furniture of each apartment. We opened every possible drawer; and I presume you know that, to a properly trained police agent, such a thing as a secret drawer is impossible. Any man is a dolt who permits a "secret" drawer to escape him in a search of this kind. The thing is so plain. There is a certain amount of bulk - of space - to be accounted for in every cabinet. Then we have accurate rules. The fiftieth part of a line could not escape up. After the cabinets we took the chairs. The cushions we probed with the fine long needles you have seen me employ. From the tables we removed the tops.'
