TLDR
A growing body of evidence suggests that there are at least two distinct Dorsal routes in the human brain, referred to as the "Grasp" and "Use" systems.About:

Embodied cognition
TL;DR: It is argued that understanding cognitive processes will need to consider the (inter)actions in the natural environment and that in cognitive tasks some independent components systematically relate to sensory processing as well as to action execution.

The lateral occipitotemporal cortex in action
Angelika Lingnau,Paul E. Downing +1 more
TL;DR: It is proposed that patterns of activity in LOTC form representational spaces, the dimensions of which capture perceptual, semantic, and motor knowledge of how actions change the state of the world.

Critical brain regions for tool-related and imitative actions: a componential analysis
TL;DR: Visual posture information and kinematic capacities are differentially critical to the three types of actions studied here: the kinematics aspect is particularly critical for imitation of meaningless movement, capacity for tool-action posture representations are particularly necessary for pantomimed gestures to the sight of tools, and both capacities inform imitation of tool-related movements.

The neural basis of human tool use.
TL;DR: Humans have two parietal systems involved in tool behavior: a biological circuit for grasping objects, including tools, and an artifactual system devoted specifically to tool use, which allows humans to understand the causal relationship between tool use and obtaining the goal, and is likely to be the basis of all technological developments.
Journal ArticleDOI
Theories and computational models of affordance and mirror systems: an integrative review.
TL;DR: The architecture and functioning of the two systems is best understood in terms of two challenges faced by complex organisms, namely: the need to select among multiple affordances and possible actions dependent on context and high-level goals and the exploitation of the advantages deriving from a hierarchical organisation of behaviour based on actions and action-goals.

The Ecological Approach to Visual Perception
TL;DR: The relationship between Stimulation and Stimulus Information for visual perception is discussed in detail in this article, where the authors also present experimental evidence for direct perception of motion in the world and movement of the self.

The visual brain in action
TL;DR: This chapter discusses vision from a biological point of view, attention, consciousness, and the coordination of behaviour in primate visual cortex, and discusses dissociations between perception and action in normal subjects.

Reorienting attention across the horizontal and vertical meridians: evidence in favor of a premotor theory of attention.
TL;DR: Neither the hypothesis postulating hemifield inhibition nor that postulating movement of attention with a constant time can explain the data, but the hypothesis of an attention gradient and that of attention movements with a constants speed are tenable in principle, but they fail to account for the effect of crossing the horizontal and vertical meridians.
