    WM hypothesis.pdf

    I have entered into a new phase of research.  In October I published a hypothesis  in Frontiers in Psychology that suggests a molecular hypothesis on how white matter changes might occur from meditation and other forms of learning.

    The paper proposes that the frontal theta found during meditation and in other forms of learning causes a cascade of molcular events that activate dormant oligodendrocytes that leads to increased myelination (pdf above).

    I have received a small grant with Chris Niell to test this hypothesis by exposing the anterior cingulate of mice to theta by use of optogenetics.  We will assay whitematter change and for each of the links in the chain discussed in the paper.

    In addition with Mary Rothbart, Chris Niell  & Yiyuan Tang we have applied for a five year grant to use studies of mice and human to develop a neural basis for the various stages of skill learning posited by Fitts and Posner (1965).

    This work should complement our longitudinal study of attention networks in children, by examaining thei  role of attention networks  in the development of skills.
