From Science Magazine comes this report on new insights into how we remember:

Recent advances in analyzing the large data sets collected during functional brain imaging studies have revealed patterns of neuronal activity that can be associated reliably with the recall of remembered stimuli. After seeing pictures or listening to sounds, subjects are able, when prompted, to retrieve or reactivate their memories of these items, and brain scans taken during the retrieval period are similar to those taken when the same items were studied directly. Polyn et al. (p. 1963) now show that reactivation of such stored representations occurs prior to a verbal report of recollection in a free recall paradigm, where subjects were not prompted to remember specific items, but were reporting which of these items "resurfaced" in their memory and when. These results provide support for the theoretical framework of shifting brain states in dynamic cognition.

Change Happens

We are not the same persons this year as last; nor are those we love. It is a happy chance if we, changing, continue to love a changed person.
-William Somerset Maugham, writer (1874-1965)

First post since August???

Where has the time gone? I'm back with a lovely quote from Democritus:

By convention there is color,
By convention sweetness,
By convention bitterness,
But in reality there are atoms and space.
--Democritus (c. 400 BCE)
