<P> The fSTS is involved in recognition of facial parts and is not sensitive to the configuration of these parts . It is also thought that this area is involved in gaze perception . The fSTS has demonstrated increased activation when attending to gaze direction . </P> <P> Bilateral activation is generally shown in all of these specialized facial areas . However, there are some studies that include increased activation in one side over the other . For instance McCarthy (1997) has shown that the right fusiform gyrus is more important for facial processing in complex situations . </P> <P> Gorno - Tempini and Price have shown that the fusiform gyri are preferentially responsive to faces, whereas the parahippocampal / lingual gyri are responsive to buildings . </P> <P> It is important to note that while certain areas respond selectively to faces, facial processing involves many neural networks . These networks include visual and emotional processing systems as well . Emotional face processing research has demonstrated that there are some of the other functions at work . While looking at faces displaying emotions (especially those with fear facial expressions) compared to neutral faces there is increased activity in the right fusiform gyrus . This increased activity also correlates with increased amygdala activity in the same situations . The emotional processing effects observed in the fusiform gyrus are decreased in patients with amygdala lesions . This demonstrates possible connections between the amygdala and facial processing areas . </P>
