Neural integration at the mesoscopic level: the advent of some ideas in the last half century

Abstract

History seen by a professional historian, based only on the documented record, always incomplete and liable to bias, can be unreliable. Modern history seen by a protagonist must surely be among the most unreliable. Yet, I must try, in a limited scope, to show the human drama as well as the flood on which we are floating, unable to dump the baggage of past biases. Our points of view, priorities, and positions on all the controversial issues and even the well established, noncontroversial ones, are not as rational as we would like to think but are strongly conditioned by where we came from. I wil depend on selected vignettes of the way things looked when I was a student, a young postdoctoral fellow and an Assistant Professor, to compare with the way they look now, in each of half a dozen mesoscopic domains--those in between the most basic subcellular or molecular and the higher levels of learning and cognition. The half dozen constitute, of course, anything but a representative fraction of neuroscience. But they add up to a nontrivial segment of the big picture with respect to the integrative aspects of our science. Most of the fronts that grew into today's popular branches are not represented, but a small set of particular interest and probability of further surprises.
