    "abstract": "This paper extends the work of Clarke [1] on the Bayesian foundations of the\nbiomagnetic inverse problem. It derives expressions for the expectation and\nvariance of the a posteriori source current probability distribution given a\nprior source current probability distribution, a source space weight function\nand a data set. The calculation of the variance enables the construction of a\nBayesian test for the appropriateness of any source model that is chosen as the\na priori infomation. The test is illustrated using both simulated\n(multi-dipole) data and the results of a study of early latency processing of\nimages of human faces.\n  [1] C.J.S. Clarke. Error estimates in the biomagnetic inverse problem.\nInverse Problems, 10:77--86, 1994.",
