“…Because participants were engaged in dummy tasks, amygdala activity can be regarded as primarily reflecting automatic processes in response to faces. Greater amygdala activation in response to faces compared with nonfacial stimuli is consistent with the results of previous neuroimaging studies (e.g., Blonder et al, 2004). However, the temporal dimension of such amygdala activation has remained unclear because of limitations associated with the temporal resolution of neuroimaging techniques.…”

“…Several neuroimaging studies have reported that, in addition to cortical visual areas such as the fusiform gyrus and superior temporal gyrus, the amygdala was more active when participants observed faces compared with control stimuli such as mosaics and houses (e.g., Ishai, Schmidt, & Boesiger, 2005;Reinders et al, 2005;Blonder et al, 2004). Animal studies have suggested that the amygdala has a long evolutionary history associated with detecting biologically significant stimuli (LeDoux, 1996).…”

Neuroimaging studies have reported greater activation of the human amygdala in response to faces than to nonfacial stimuli, yet little is known about the temporal profile of this activation. We investigated this issue by recording the intracranial field potentials of the amygdala in participants undergoing preneurosurgical assessment (n = 6). Participants observed faces, mosaics, and houses in upright and inverted orientations using a dummy target detection task. Time-frequency statistical parametric mapping analyses revealed that the amygdala showed greater gamma-band activity in response to faces than to mosaics at 200-300 msec, with a peak at 255 msec. Gamma-band activation with a similar temporal profile was also found in response to faces versus houses. Activation patterns did not differ between upright and inverted presentations of stimuli. These results suggest that the human amygdala is involved in the early stages of face processing, including the modulation of subjective perception of faces.

“…Complexity, in this context, may be defined by the number of neural operations required before a stimulus can be perceived (Faubert, 2002). Within this framework, faces can be construed as more complex than objects because they recruit more extensive neural circuitry for perception and recognition (Blonder et al, 2004;Haxby, Hoffman, & Gobbini, 2000;Puce, Allison, Asgari, Gore, & McCarthy, 1996). For example, faces, but not objects, possess a wealth of information that facilitates social communication.…”

Recognition of faces and complex objects in younger and older adults

We examined whether (1) age-associated impairments in face recognition are specific to faces or also apply to within-category recognition of other objects and (2) age-related face recognition deficits are related to impairments in encoding second-order relations and holistic information. In Experiments 1 and 2, we found reliable age differences for recognition of faces, but not of objects. Moreover, older adults (OAs) and younger adults (YAs) displayed similar face inversion effects. In Experiment 3, unlike YAs, OAs did not show the expected decline in performance for recognition of composites (Young, Hellawell, & Hay, 1987). In Experiment 4, both OAs and YAs showed a whole/part advantage (Tanaka & Farah, 1993). Our results suggest that OAs have spared function for processing of secondorder relations and holistic information. Possible explanations for the finding that OAs have greater difficulty recognizing faces than recognizing other objects are proposed.

“…Gray matter volume within the occipital cortex is related to general cognitive intelligence (Haier, Jung, Yeo, Head, & Alkire, 2004), and this region is known to be an important visual association region of the brain, involved in simple feature analysis (Boucart et al, 2000), generation of mental imagery (D'Esposito et al, 1997), mental image transformation (Boucart et al, 2000), and biological motion (Vaina, Solomon, Chowdhury, Sinha, & Belliveau, 2001), as well as the processing of faces and other complex visual stimuli (Blonder et al, 2004). The present findings suggest that adolescents with higher EQ show greater activation of this visual association region during the processing of facial cues of fear.…”

The somatic marker hypothesis posits a key role for the ventromedial prefrontal cortex, amygdala, and insula in the ability to utilize emotions to guide decision making and behavior. However, the relationship between activity in these brain regions and emotional intelligence (EQ) during adolescence, a time of particular importance for emotional and social development, has not been studied. Using functional magnetic resonance imaging (f MRI), we correlated scores from the Bar-On Emotional Quotient Inventory, Youth Version (EQ-i:YV) with brain activity during perception of fearful faces in 16 healthy children and adolescents. Consistent with the neural efficiency hypothesis, higher EQ correlated negatively with activity in the somatic marker circuitry and other paralimbic regions. Positive correlations were observed between EQ and activity in the cerebellum and visual association cortex. The findings suggest that the construct of self-reported EQ in adolescents is inversely related to the efficiency of neural processing within the somatic marker circuitry during emotional provocation.
