Zusammenfassung
This article offers a conceptual framework for integrated analysis
of subprocesses in action and language, based on goal-directed action.
Anatomical substrates are discussed in the companion paper (Arbib
and Bota, 2003) which approaches "Integrative Models of Broca's Area
and the Ventral Premotor Cortex" within the context of explaining
why the evolution of the human brain yielded mechanisms which support
language in a multi-modal vocal-manual-facial system rather than
privileging the vocal mode. Arbib and Bota (2003) examine homologies
between different cortical areas in macaque and human to revisit
the Mirror System Hypothesis (MSH) of Rizzolatti and Arbib (1998)--the
notion that the mirror system for grasping (which has its frontal
outpost in premotor area F5 of the macaque) provides the substrate
for the evolution of the language-ready brain which supports parity
of communication. They also offer a critique and extension based
on the work of Aboitiz and Garc�a (1997; Aboitiz et al., 2006). Arbib
and Bota (2003) also discussed the utility of neuroinformatics in
relating information across diverse cortical atlases and evaluating
degrees of homology for brain regions of interest in different species
(for discussion, see Deacon, 2004; Arbib and Bota, 2004).
