A proposal by two eminent biological scientists for a mechanism
whereby mind becomes manifest from the operations of brain tissue.
This significant contribution to neuroscience consists of two
papers, the first by Mountcastle an, the second by Edelman. Between
them, they examine from different but complementary directions the
relationships that connect the higher brain-memory, learning,
perception, thinking-with what goes on at the most basic levels of
neural activity, with particular stress on the role of local
neuronal circuits.Edelman's major hypothesis is that "the conscious
state results from phasic reentrant signaling occurring in parallel
processes that involve associations between stored patterns and
current sensory or internal input." This selective process occurs
by the polling of degenerate primary repertoires of neuronal groups
that are formed during embryogenesis and development. Edelman's
theory extrapolates to the brain the selectionistic immunological
theories for which he was awarded the 1972 Nobel Prize in
Physiology or Medicine. Mountcastle's paper reviews what is known
about the actual structure of various parts of the neo cortex. He
relates the large entities of the neocortex to their component
modules-the local neuronal circuits-and shows how the complex
interrelationships of such a distributed system can yield dynamic
distributed functioning. There are strong conceptual parallels
between Mountcastle's idea of cortical columns and their functional
subunits and Edelman's concept of populations of neurons
functioning as processors in a brain system based on selectional
rather than instructional principles. These parallels are traced
and put into perspective in Francis Schmitt's Introduction.
