The mirror-neuron system. (2004, neutral): “…clear evidence has been accumulating in recent years that human area 44, in addition to speech representation, contains (as does monkey area F5) a motor representation of hand movements (Binkofski et al. 1999, Ehrsson et al. 2000, Gerardin et al. 2000, Iacoboni et al. 1999, Krams et al. 1998).”
Design of a cybernetic hand for perception and action (2006, background): “Even the simplest of hand actions—such as power grasps—engage large parts of the human brain (Ehrsson et al. 2000), and humans require almost a decade of training until they perform the apparently simple task of grasping, lifting, and holding an object with an adult coordination pattern (Forssberg…”
Neural Dynamics of Learning Sound—Action Associations (2008, background): “Specifically, those regions within the motor system that are known to be involved in performing complex gestures of the primary affectors, the hand and orofacial muscles such as the ventral premotor cortex [2–6].”
Visually guided grasping produces fMRI activation in dorsal but not ventral stream brain areas (2003, background): “Indeed, one PET study reported significant activation of an area near our putative AIP during grasping (vs. reaching) and near-significant activation of the same area during a task which involved matching 3D objects (Faillenot et al. 1997b).”
Grasping the Intentions of Others with One's Own Mirror Neuron System (2005, neutral): “execution of finger movements (‘‘mirror neuron system’’) [10,11,12,13,14,15,16,17,18,19,20,21,25,26,27].”
Two different streams form the dorsal visual system: anatomy and functions (2003, background): “The homology between human and monkey grasping circuits is further supported by the demonstration that the dorsal sector of the “pars opercularis” of the inferior frontal gyrus (that is of the area considered to be the human homologue of the monkey’s area F5; see Petrides and Pandya 1997) becomes ac”
Are there theory of mind regions in the brain? A review of the neuroimaging literature (2009, background): “Although it has been suggested that mirror neurons (MNs) mediate the simulation of mental states [Gallese and Goldman, 1998], the proposed ventral locus is inconsistent with reports of MN-like properties in more lateral regions of the frontal cortex [Ehrsson et al., 2000; Iacoboni et al., 1999; Kram”
Neural Circuits Involved in the Recognition of Actions Performed by Nonconspecifics: An fMRI Study (2004, background): “It is interesting to note that this sector is also active during the execution of grasping (Ehrsson et al., 2000; Gerardin et al., 2000; Binkofski et al., 1999) as well as during the observation of hand actions (Manthey et al.”
Intrinsic fluctuations within cortical systems account for intertrial variability in human behavior. (2007, result): “Button-Press Apparatus The button-press force transducer was similar to that reported by other groups (Ehrsson et al., 2000).”
TRoPICALS: a computational embodied neuroscience model of compatibility effects. (2010, background): “This goes against the empirical evidence showing that the opposite happens in real brains, namely that the prefrontal cortex, rostral cingulate cortex, parietal cortex, and premotor cortex (but not primary motor cortex) tend to have a larger activation with small objects than with large ones (Ehrsso”
Activations related to "mirror" and "canonical" neurones in the human brain: an fMRI study (2003, background): “…simulation of hand movements (Grafton et al., 1997; Lacquaniti et al., 1997; Krams et al., 1998; Binkofski et al., 1999, 2000; Joliot et al., 1999; Chao and Martin, 2000; Ehrsson et al., 2000, 2001; Kollias et al., 2001; Rushworth et al., 2001a; Gerlach et al., 2000, 2002; Simon et al., 2002).”
