Gl. Ahern et al., AFFECTIVE SELF-REPORT DURING THE INTRACAROTID SODIUM AMOBARBITAL TEST, Neuropsychology, development, and cognition. Section A, Journal of clinical and experimental neuropsychology, 16(3), 1994, pp. 372-376
Changes in internal affective state were investigated in patients unde
rgoing the intracarotid sodium amobarbital test. It was found that whe
n the left hemisphere was inactivated, patients rated their mood as si
gnificantly more negative than during baseline conditions. No signific
ant change in affective state was observed during the inactivation of
the right hemisphere. The findings are interpreted in terms of a diffe
rential lateralization model of emotion, in which the right hemisphere
is more involved in the more powerful and salient negative affects.
