At the start of the 20th century, a German neuroanatomist named Korbinian Brodmann
parceled the human cortex into nearly 50 different areas by looking at the structure and organization of sections of brain under a microscope.
(18681918) worked at that institute and classified there in the first decade of 20th century the whole cortex into 45 distinct areas based on morphologic characteristics of the grey matter .
To assign anatomical labels to the places in three-dimensional space, different kinds of templates are used, for example the already more than 100-year-old map of Korbinian Brodmann
based on microscopic investigations of brain tissue, the map of a dissected brain of a 60-year-old French woman in a so-called Talairach space, or the MNI-atlas based on 305 anatomical MRI images of young, right-handed, North-American and mostly male healthy volunteers.
According to the maps of the cerebral cortex developed by Korbinian Brodmann
, which are still in use today, Broca's region is composed of two areas.
Along with his colleague Korbinian Brodmann
, Dr Vogt experimented with a range of self-hypnosis techniques which he found could relieve many stress-related symptoms and diseases.
