Dedicated to the communication of news, science, and information of interest to the brain mapping community, and to sharing and promoting the science of brain mapping.
The purpose and goal of brain mapping is to advance the understanding of the relationship between structure and function in the human brain. Scientists in this field seek to gain knowledge of the physical processes that underlie human sensation, attention awareness and cognition. These results are immediately applicable to surgical intervention, to the design of medical interventions and to the treatment of psychological and psychiatric disorders.

Novelty in the BrainMap database can be spotted using mathematical modeling of the activation foci. The novelty is detected as a discrepancy between the 3D coordinates and the anatomical label. The method finds a few entry errors in BrainMap together with a few errors in the original articles. The result is available as an automatic generated list of BrainMap outliers (Note the functional interface to the BrainMap database has been changed so the URL for the database does not work).Technical:The mathematical modeling is based on probability density modeling using the Specht kernel density estimate (Parzen window) applied on the 3D Talairach space conditioned on the words and phrases of the anatomical label. Novelty detection is implemented by directly ranking the likelihood.
