Naming pictures of tools, answering questions about tools, and generating action words in response to object pictures or their written names show enhanced activity in the left middle temporal gyrus. Moreover, we have suggested that these regions are involved in both perceiving and knowing about features and properties critical for object identification (e.g., Martin, 1998).ДЇor example, activity in posteriolateral left temporal cortex, just anterior to primary motion processing area MT, has been reported in multiple studies of object semantics. These and related findings have led us to suggest that information about different object attributes and features are stored in these regions of cortex. In contrast, manipulable objects such as tools and utensils show heightened activity relative to animate objects in the medial portion of the fusiform gyrus (e.g., Chao et al., 1999), posterior region of the left middle temporal gyrus (e.g., Chao et al., 1999 Moore & Price, 1999), and in left intraparietal and ventral premotor cortices (e.g., Chao & Martin, 2000).ДЄlthough these object category-related patterns of activity have most often been found with tasks using object pictures, they have also been found when objects are represented by their written names (see above-cited reviews). For example, animate objects, as represented by pictures of human faces (e.g., Haxby, Ungerleider, Clark, Shouten, Hoffman, & Martin, 1999 Ishai, Ungerleider, Martin, Shouten, & Haxby, 1999 Kanwisher McDermott, & Chun, 1997), human figures ( Beauchamp, Lee, Haxby, & Martin, 2002), and animals (e.g., Chao, Haxby, & Martin, 1999), show heightened activity in the lateral region of the fusiform gyrus and in STS, relative to a number of other object categories (houses, tools, chairs). Moreover, different object categories evoke distinct patterns of activity in these regions (for recent reviews, see Josephs, 2001 Martin 2001 Martin & Chao, 2001 Thompson-Schill, 2002). It has also been established that many of these activations are found in processing streams associated with perception of specific object features such as form and colour (ventral occipitotemporal cortex), motion (posterior lateral temporal cortex specifically, the middle temporal gyrus and superior temporal sulcus, and with grasping and manipulating objects (left intraparietal sulcus and ventral premotor cortices). Many of these investigations have shown that object categories are represented by neural activity distributed across wide spread regions of cortex. Reports of category-specific impairments following brain injury or disease have motivated an ever-increasing number of functional imaging studies on category representation in the normal human brain. Within the social domain, the network includes regions involved in processing and storing information about the form and motion of biological objects, and in perceiving, expressing, and regulating affective responses. Perceiving and understanding social and mechanical concepts depends, in part, on activity in distinct neural networks. Moreover, social, but not mechanical, interpretations elicited activity in regions implicated in the perception and modulation of emotion (right amygdala and ventromedial prefrontal cortex). In contrast, vignettes interpreted as conveying mechanical actions resulted in activity in posterior temporal lobe sites associated with identifying manipulable objects such as tools. This neural system included regions in posterior temporal cortex associated with identifying human faces and other biological objects.

Vignettes interpreted as conveying social interactions elicited a distinct and distributed pattern of neural activity, relative to vignettes interpreted as mechanical actions.

To investigate this issue, functional magnetic resonance imaging (fMRI) was used to record changes in neural activity while subjects interpreted animated vignettes composed of simple geometric shapes in motion. However, the extent to which these category-related activation patterns reflect differences in conceptual representation remains controversial. Motivated by neuropsychological investigations of category-specific impairments, many functional brain imaging studies have found distinct patterns of neural activity associated with different object categories.
