Native and Recombinant DM-GRASP Selectively Support Neurite Extension from Neurons That Express GRASP

Heterophilic interactions of DM-GRASP: GRASP-NgCAM interactions involved in neurite extension

DM-GRASP is an immunoglobulin superfamily cell adhesion molecule that is expressed in both the developing nervous and immune system. Specific populations of neurons respond to DM-GRASP substrates appears to require homophilic interactions between DM-GRASP molecules. We were interested in determining whether DM-GRASP interacts heterophilically with other ligands as well. We have found that eleve...

Grasp that optimises objectives along post-grasp trajectories

In this article, we study the problem of selecting a grasp pose on the surface of an object to be manipulated by considering three post-grasp objectives. These objectives include (i) kinematic manipulation capability [1], [2], (ii) torque effort [3] and (iii) impact force in case of collision [4] during post-grasp manipulative actions. In these works [1]–[4], the main assumption is that a manip...

Grasp synthesis from low-dimensional probabilistic grasp models

We propose a novel data-driven animation method for the synthesis of natural looking human grasping. Motion data captured from human grasp actions is used to train a probabilistic model of the human grasp space. This model greatly reduces the high number of degrees of freedom of the human hand to a few dimensions in a continuous grasp space. The low dimensionality of the grasp space in turn all...

The hand that ‘sees’ to grasp

New findings advance our understanding of how vision is used to guide the hand during object grasping.
