Depression & Anxiety
In some clinical conditions the emotional side of the individual interferes in learning. The figure below represents a learning disability situation in which the over-activation of the right hemisphere in response to a task requiring left hemisphere involvement presents a possible reason for the lowered performance.
The colors of the circle indicated the standard deviation (SD) difference from the normative reference group. The white color indicates that the subject was within the range between +.50 and -.50 standard deviations. The light blue indicates the subject was between -.50 and -1.50 SD. The dark blue indicates the subject’s value was below -1.50 SD. Light orange indicates the subject was between +.50 SD and +1.50 SD while the dark orange indicates a value above +1.50 SD. The number in the circle is the raw value.
The following head figure presents the SD values for a subject during eyes closed. Red indicates that the SD values were 3 SD above the norm. The subject was reporting very high levels of anxiety during this period (a level 9 on a scale of 1 to 10, with 10 being the highest. The Beta2 frequency is 32 to 64 Hertz. Note the elevations appear more focused in the left posterior region than the right posterior locations.
