Moreover, a significant decline of emotion recognition skills (particularly affecting the identification of negative emotions) has been found related to microstructural changes (measured through fractional anisotropy) in right inferior longitudinal fasciculus and inferior frontooccipital
fasciculus in nondemented ALS patients .
Some studies mentioned a nonspecific headache area [10, 11, 21] as patients differently specified the headache location as diffuse  or pancephalic , hemicranial, periorbital, bifrontal, frontooccipital
, parietal , temporal, or postauricular , and even in the maxillary area .
They found reduced global brain functional connectivity and reduced strength in frontotemporal, frontooccipital
, and temporooccipital connections in TR-SCZ.
A different study found that damage anywhere to the inferior frontooccipital
fasciculus or the inferior longitudinal fasciculus is associated with impaired emotion recognition .
In contrast to these circular erect head shapings pressure exerted by boards pads or stones that were attached with straps bound around the child's head modified the forehead or the back of the head, or both regions; the latter being defined as frontooccipital
(= antero-posterior) compression.
The fur on the skin over the frontooccipital
region was shaved, and the skin grasped with fine sandpaper and cleaned with acetone, and a BIS adhesive electrode (Zipprep, Aspect Medical Systems, Natick, MA) was placed in the left side of the head in the following position: number 1 electrode was placed over the external occipital protuberance; number 2 and number 4 electrodes were placed over the left hemisphere; number 3 electrode was placed over the rostral left portion of the frontal bone, at the level of the left eye.
The anatomical landmarks used to ensure the accuracy and reproducibility of the measurement include a midline falx, thalami symmetrically positioned on either side of the flax and visualization of the Septum Pellucidum at one third the frontooccipital
