Vectorial coding of movement: Vision, proprioception, or both?
-
The authors report on a pointing study in which the moving hand, but not the target of the movement, was viewed through prisms that induced a visual displacement of the hand. Kinematic analyses of early directional errors were not explained by the use of visual information alone. The authors conclude that direction coding is based upon a weighted fusion of visual and proprioceptive information about hand position.

Trajectory adaptation to a nonlinear visuomotor transformation: Evidence of motion planning in visually perceived space
-
Subjects executed pointing movements during which vision of their moving arm was prevented. Instead, visual feedback was relayed in real-time via a virtual reality display. Feedback was provided either in hand space (Cartesian coordinates) or in joint space. The results demonstrate that when visual feedback was provided in 'joint' space, subjects adapted their movements to produce perceptually straight reaches, even though the spatial (Cartesian) hand paths for these reaches were markedly curved. The authors conclude that reaching movements may be planned so as to produce straight paths in visually perceived space.

Selective reaching to grasp: Evidence for distractor interference effects
-
in press. Demonstrates how attentional processes may modify reaching kinematics. Subjects reached for a target object that was sometimes accompanied by a behaviourally non-relevant 'distractor' object. In all trials, vision was ini-tially occluded. The results demonstrate that on trials where a distractor was present, movement trajectories were biased away from the distractor. A similar phenomenon has also been demonstrated by Sheliga, Riggio and Rizzolatti [70] for oculomotor movements.

A kinematic analysis of goal-directed prehension movements executed under binocular, monocular, and memory-guided viewing conditions
-
in press. Examines the role of binocular vision in the 'on-line' control of reaching. Subjects executed prehension movements toward a single target object, or to a target object accompanied by a behaviourally non-relevant distractor. Visual feedback was manipulated so that during the reach, vision was binocular, monocular, or removed completely. The results indicate that binocular vision contributes to the on-line control of prehension movements, particularly during 'selective' reaches.

A motor signal and 'visual' size perception.
-
A preliminary report of an ingenious study examining how kinaesthesis may serve to update a 'visual' representation of the arm. Subjects were placed in complete darkness and dark-adapted. On each trial, they briefly viewed their hand illuminated by a powerful electronic flash, thereby producing a strong after-image of their hand: Following the flash, subjects either moved their arm or had it moved by the experimenter, and were required to estimate the magnitude of any perceived changes in the size of the hand after-image. Regardless of whether the movements were active or passive, subjects consistently reported that the after-image appeared larger when their hand moved away from them, and smaller when hand movements were toward the body. However, when the hand that was moved was not the one that produced the after-image, no changes in perceived size were reported

However, when the hand that was moved was not the one that produced the after-image, no changes in perceived size were reported. These results indicate that visual and proprioceptive signals may be rapidly fused to yield an integrated representation of limb position.

The sources of visual information to the primate frontal lobe: A novel role for the superior parietal lobule
-
An excellent review describing the visuomotor function of the superior parietal lobe and its projections to dorsolateral pre-motor areas. The authors suggest that projections to dorsal pre-motor cortex originating in the medial intraparietal (MIP) area and area 7m form a medial pathway for controlling the transport (reach) phase of visually guided prehension movements. This pathway is seen as operating in parallel to a lateral system linking area AIP to ventral pre-motor cortex and to be involved in the control of grasping movements.

A retrograde tracer study that reports on the neuronal projections to the orbital and medial prefrontal cortex. The authors show that orbital and medial prefrontal regions receive substantial projections from ventral pre-motor cortex, parietal areas 7b and AIP, and the hand, arm and face regions of somatosensory cortex. It is suggested that these projections form part of a network for controlling the arm movements used in feeding.

A study of reaching movements in which precise control of limb posture before and after the movement was required. The authors report that neuronal activity in dorsolateral pre-motor cortex is phasic and, for the most part, confined to the period before movement onset. The authors propose that the functional role of dorsolateral pre-motor cortex may lie in movement selection and planning.

Deciding not to go - Neuronal correlates of response selection in a go/nogo task in primate premotor and parietal cortex
-
These authors report a GO/NO-GO reaching task in non-human primates. Visual cues presented during an instructed delay period allowed the monkey to prepare or withhold a forthcoming movement. The decision to withhold a motor response was reflected in the neuronal response of cells within the dorsal pre-motor area. Pre-motor cells displayed markedly different response patterns on GO/NO-GO trials. This was not observed for cells in parietal area 5, which showed directionally selective responses on both GO and NO-GO trials

Temporal encoding of movement kinematics in the discharge of primate primary motor and premotor neurons
-
Reports a statistical analysis of the firing properties of dorsal pre-motor cells. The results of these analyses suggest several things. First, that movement parameters such as direction, amplitude, velocity, etc. can be correlated with the firing rate of single neurons. Second, that pre-motor cell responses may participate in coding multiple movement parameters. Finally, that different parameters may be coded at different stages of the movement. A finding of considerable relevance for functional models of reaching is that the point where cell activity is maximally associated with movement, amplitude (distance) occurs primarily after peak movement velocity has been reached. This suggests that the coding of movement velocity and movement amplitude may be independent processes

Examines the visual response properties of neurons located within the rostral area of ventral pre-motor cortex (F5). The paper's primary finding is the existence of a subset of F5 neurons, termed 'mirror1 neurons, that selectively respond when a monkey executes a hand movement or observes the experimenter or another monkey execute a similar hand movement. The relevance of these neurons to understanding motor action is discussed.

Reviews the functional properties of F5 'mirror' neurons 45** within the context of an action recognition system for understanding motor events. The authors discuss the possibility that a homologous system may exist in humans, and that this may have formed the basis for early gestural communication systems. They suggest that such a system may have served as a precursor for the development of speech-based communication in humans.

Localization of grasp representations in humans by positron emission tomography. 2. Observation compared with imagination
-
in press. One of two papers (see also [48*]) aimed at identifying the brain areas involved in the control of grasping movements using PET. This paper contrasted the observation of a grasping movement performed by the experimenter with a condition in which subjects imagined themselves grasping the same object. The results indicated that observing a grasping movement activated area 45. In contrast, imagining a grasping movement activated a more caudal region, area 44. The authors suggest these areas form part of separate neural circuits involved in 'understanding' motor events and controlling hand movements.
