Executive Function Disorder
The frontal lobes represent a large area
of the brain and brain centers within
the frontal lobe have numerous
interconnections with other parts of
the brain.
These include connections with emotion
and mood centers as well as cognitive
centers.
Executive Function Disorder
This high degree of complexity results in
a number of syndromes that are
associated with lesions of this area.
There are three general anatomical
divisions of the frontal cortex: the
limbic, the precentral and the
prefrontal cortices.
The Frontal Lobes
The precentral cortex consists of areas
that lie immediately before the
central sulcus.
These consist of the primary and
secondary motor control areas.
The Frontal Lobes
The limbic component consists of
the inferior and medial parts of the
cingulate gyrus and the posterior
parts of the orbital frontal areas.
These areas have inter‐ connections
with the amygdala, hippocampus,
thalamus and other parts of the
limbic system.
