After the autopsy, half of the donated brain is sent to the pathologist and the remaining half is collected by the Maritime Brain Tissue Bank (MBTB). The brain is then 'fixed' to preserve the tissue and transferred to a storage solution. At this point, the tissue is available for use in scientific research.
The brains are made available for research for approximately ten years. If there is any tissues remaining after which they are returned to the morgue for disposal. The MBTB receives a number of brain donations each year, from a diverse range of neurodegenerative disorders. 'Normal' brains are also donated and are important in research as control specimens to which other tissue can be compared to.
