“…The observed hand behaviour was consistent with what has been seen in previous grasping studies (Gentilucci et al, 1991;Jakobson & Goodale, 1991;Jeannerod, 1986;Paulignan, Jeannerod, MacKenzie, & Marteniuk, 1991). Participants demonstrated accurate grip scaling, opening their hand the widest for the largest block (Fig.…”

The development of noninvasive neuroimaging techniques, such as fMRI, has rapidly advanced our understanding of the neural systems underlying the integration of visual and motor information. However, the fMRI experimental design is restricted by several environmental elements, such as the presence of the magnetic field and the restricted view of the participant, making it difficult to monitor and measure behaviour. The present article describes a novel, specialized software package developed in our laboratory called Biometric Integration Recording and Analysis (BIRA). BIRA integrates video with kinematic data derived from the hand and eye, acquired using MRI-compatible equipment. The present article demonstrates the acquisition and analysis of eye and hand data using BIRA in a mock (0 Tesla) scanner. A method for collecting and integrating gaze and kinematic data in fMRI studies on visuomotor behaviour has several advantages: Specifically, it will allow for more sophisticated, behaviourally driven analyses and eliminate potential confounds of gaze or kinematic data.

“…Object location perturbations are also perturbations in distance between wrist marker and target (e.g., ¡20°/32 cm to 0°/30 cm; 0°/30 cm to 20°/32 cm). It is well known that movement amplitude has an eVect on movement time, latency, transport velocity and grasp aperture (Gentilucci et al, 1991). The perturbation of both object position and distance results in the attenuation of the direction eVect for most measures seen in direct prehension, except for transport velocity amplitude and grasp aperture, suggesting a putative coordination between the two visuomotor channels.…”

“…One result on which most agree is that transport velocity (of the wrist) and movement amplitude are a direct consequence of the distance between the hand and the object (Gentilucci et al, 1991). However, varying the location of the object yields conXicting results with respect to the grasping module.…”

Prehension movements of the right hand were recorded in a right-handed man (AC), with an injury to the left posterior parietal cortex (PPC) and with a section of the left half of the splenium. The kinematic analysis of AC's grasping movements in direct and perturbed conditions was compared to that of Wve control subjects. A novel eVect in prehension was revealed-a hemispace eVect-in healthy controls only. Movements to the left hemispace were faster, longer, and with a smaller grasp aperture; perturbation of both object position and distance resulted in the attenuation of the direction eVect on movement time and the time to velocity peak, with a reverse pattern in the time to maximum grip aperture. Nevertheless, the correlation between transport velocity amplitude and grasp aperture remained stable in both perturbed and non-perturbed movements, reXecting the coordination between reaching and grasping in control subjects. In contrast, transport and grasp, as well as their coordination in both direct and perturbed conditions, were negatively aVected by the PPC and splenium lesion in AC, suggesting that transport and grasp rely on two functionally identiWable subsystems. 

“…The concept of coupling between the reach and grasp motions is inspired by extensive evidence in neuro-physiological studies [10,13,[30][31][32][33][34][35]. The most frequently reported mechanism suggests a parallel, but time-coupled evolution of the reach and grasp motions with synchronized termination.…”
