Overlapping neural correlates of reading emotionally positive and negative adjectives.

Demirakca T, Herbert C, Kissler J, Ruf M, Wokrina T, Ende G - Open Neuroimag J (2009)

Bottom Line: Comparison of positive and negative naturally read adjectives to neutral adjectives yielded an overlapping higher BOLD response in the occipital and the orbitofrontal cortex (gyrus rectus).Superior medial frontal gyrus and posterior cingulate gyrus showed higher BOLD response to negative adjectives and inferior frontal gyrus to positive adjectives.The overlap of activated regions and lack of pronounced distinct regions supports the assumption that the processing of negative and positive words mainly takes place in overlapping brain regions.

ABSTRACT
Comparison of positive and negative naturally read adjectives to neutral adjectives yielded an overlapping higher BOLD response in the occipital and the orbitofrontal cortex (gyrus rectus). Superior medial frontal gyrus and posterior cingulate gyrus showed higher BOLD response to negative adjectives and inferior frontal gyrus to positive adjectives. The overlap of activated regions and lack of pronounced distinct regions supports the assumption that the processing of negative and positive words mainly takes place in overlapping brain regions.

Figure 1: Areas with significantly greater BOLD response to negative adjectives (red spots) and positive (green spots) compared to neutral adjectives (p=< 0.01 for visualization purposes).

Mentions: The direct comparison between positive and negative adjectives resulted in stronger activation elicited by negative adjectives in the frontal superior medial gyrus (BA8, -3, 45, 54, k=27, Z=2.92, p=0.002). This activation overlapped with the negative to neutral comparison for which the most notable focus of activation was found bilateral in the superior part of the medial frontal cortex (BA 8, 9), extending to SMA (BA6) (Fig. 1A, red spots). Additionally increased BOLD responses to negative adjectives were noted in the orbitofrontal region, more precisely in the left gyrus rectus (Fig. 1C, red spots). Further BOLD differences were observed in the middle occipital lobes, bilaterally (Fig. 1D, red spots), the left angular gyrus and the left posterior cingulate cortex (Fig. 1B, red spots). For local maxima see Table 1.
