Early studies of sleep and dreaming were crucially dependent on waking subjects up during sleep to find out whether they are dreaming or not. Using that strategy, it was found that when the eyes are rapidly moving (REM sleep) people are usually dreaming; when the eyes are not moving, there may be some mentation, but little in the way of visually rich dreams.
Patricia ChurchlandThere are many levels of organization in nervous systems. Hence we aim to explain mechanisms at one level in terms of properties and dynamics at a lower level, and to fit that in with the properties at the higher levels.
Patricia ChurchlandIf you want to understand the nature of something, to find out the truth, that is one thing. If you want to play semantics, make up wild thought 'experiments', that is another thing. I am not so interested in the latter, though I do appreciate that it can be fun, however unproductive.
Patricia ChurchlandI had no idea what philosophy was until I went to college at UBC. I first read Hume and Plato, so naturally I was under the misapprehension that philosophers are trying to figure out what is true, and that contemporary philosophers are mainly trying to figure out what is true about the mind. Of course Hume and Plato were trying to do that, hence my misapprehension.
Patricia ChurchlandEventually I realized that for contemporary philosophers conceptual analysis per se was an end in itself. For some, it was somehow supposed to lead to the truth about these phenomena, not just to tidy things up a bit.
Patricia ChurchlandI used to suspect that in the brain, time is its own representation. I now think the problem is so much more complicated. Initially I was rather impressed by the experiments showing that on complex problems, subjects who are distracted do better in getting an answer than either those who answer immediately or those who spend time reflecting on the problem.
