“…A principal feature of both models is that variability in movement trajectories is not problematic (Bizzi et al, 1984;Flash and Hogan, 1985;Harris and Wolpert, 1998), because the end goal of the movement is achieved as a result of afferent feedback. In addition, these models can account for well described in-flight corrections of movement trajectories following perturbations of both systems [limb (Todorov and Jordan, 2002;Kording and Wolpert, 2004); gaze (Guitton et al, 2003)]. At the neuronal level, the present results clearly demonstrate the convergence of oculomotor and headmovement-related afferent information up to the final stages of premotor processing in the gaze control system.…”

“…Two general classes of models have emerged that can account for the control of eye-head gaze shifts. In the first, a single controller is used to minimize gaze error rather than enforce a specific eye or head trajectory (Scudder et al, 2002;Guitton et al, 2003), making it conceptually analogous to optimal feedback control. Alternatively, it has been proposed that a gaze displacement command is decomposed early on to control separate eye and head comparators Sparks, 1999;Freedman, 2001;Quessy and Freedman, 2004).…”

Simple activities like picking up the morning newspaper or catching a ball require finely coordinated movements of multiple body segments. How our brain readily achieves such kinematically complex yet remarkably precise multijoint movements remains a fundamental and unresolved question in neuroscience. Many prevailing theoretical frameworks ensure multijoint coordination by means of integrative feedback control. However, to date, it has proven both technically and conceptually difficult to determine whether the activity of motor circuits is consistent with integrated feedback coding. Here, we tested this proposal using coordinated eye-head gaze shifts as an example behavior. Individual neurons in the premotor network that command saccadic eye movements were recorded in monkeys trained to make voluntary eye-head gaze shifts. Head-movement feedback was experimentally controlled by unexpectedly and transiently altering the head trajectory midflight during a subset of movements. We found that the duration and dynamics of neuronal responses were appropriately updated following head perturbations to preserve global movement accuracy. Perturbation-induced increases in gaze shift durations were accompanied by equivalent changes in response durations so that neuronal activity remained tightly synchronized to gaze shift offset. In addition, the saccadic command signal was updated on-line in response to head perturbations applied during gaze shifts. Nearly instantaneous updating of responses, coupled with longer latency changes in overall discharge durations, indicated the convergence of at least two levels of feedback. We propose that this strategy is likely to have analogs in other motor systems and provides the flexibility required for fine-tuning goal-directed movements.

“…A second possible explanation is that head movements directly affect whisker motion, so that the whiskers move "equal and opposite" to the head. In the visual system, the VOR ensures that the eyes compensate for head rotations in three dimensions, thus stabilizing the image on the retina (Guitton et al, 2003;Land, 2004). Because the whiskers exhibit very little vertical motion (Bermejo et al, 2002), we would not expect them to compensate for vertical head movements.…”

“…An example of mechanical compensation for selfmovement occurs during visual exploration: during a combined head-eye gaze shift, the eyes lead the head in making an initial saccade to a new spatial location. Subsequent head motion is then canceled out through the vestibulo-ocular reflex (VOR), which moves the eye with a velocity equal and opposite to that of the head (Guitton et al, 2003;Land, 2004).…”

Rats use rhythmic movements of their vibrissae (whiskers) to tactually explore their environment. This "whisking" behavior has generally been reported to be strictly synchronous and symmetric about the snout, and it is thought to be controlled by a brainstem central pattern generator. Because the vibrissae can move independently of the head, however, maintaining a stable perception of the world would seem to require that rats adjust the bilateral symmetry of whisker movements in response to head movements. The present study used high-speed videography to reveal dramatic bilateral asymmetries and asynchronies in free-air whisking during head rotations. Kinematic analysis suggested that these asymmetric movements did not serve to maintain any fixed temporal relationship between right and left arrays, but rather to redirect the whiskers to a different region of space. More specifically, spatial asymmetry was found to be strongly correlated with rotational head velocity, ensuring a "look-ahead" distance of almost exactly one whisk. In contrast, bilateral asynchrony and velocity asymmetry were only weakly dependent on head velocity. Bilateral phase difference was found to be independent of the whisking frequency, suggesting the presence of two distinct left and right central pattern generators, connected as coupled oscillators. We suggest that the spatial asymmetries are analogous to the saccade that occurs during the initial portion of a combined head-eye gaze shift, and we begin to develop the rat vibrissal system as a new model for studying vestibular and proprioceptive contributions to the acquisition of sensory data.

“…These include the frontal eye fields (Chen 2006;Elsley et al 2007;Knight and Fuchs 2007;Monteon et al 2005;Tu and Keating 2000;van der Steen et al 1986), the supplementary eye fields (Chen and Walton 2005;MartinezTrujillo et al 2003MartinezTrujillo et al , 2004, and the superior colliculus (Freedman and Sparks 1997a;Freedman et al 1996;Klier et al 2001;Martinez-Trujillo et al 2003;Walton et al 2007Walton et al , 2008. Previous studies have provided evidence in support of a single gaze controller that programs both the eye and head components (Galiana and Guitton 1992;Guitton 1992;Guitton et al 2003;Lefèvre and Galiana 1992;Sparks et al 2001). Thus our results are consistent with attentional modulation of neural activity within this SEF-FEF-SC network representing the common gaze pathway.…”

Khan AZ, Blohm G, McPeek RM, Lefèvre P. Differential influence of attention on gaze and head movements. J Neurophysiol 101: 198 -206, 2009. First published November 5, 2008 doi:10.1152/jn.90815.2008. A salient peripheral cue can capture attention, influencing subsequent responses to a target. Attentional cueing effects have been studied for head-restrained saccades; however, under natural conditions, the head contributes to gaze shifts. We asked whether attention influences head movements in combined eye-head gaze shifts and, if so, whether this influence is different for the eye and head components. Subjects made combined eye-head gaze shifts to horizontal visual targets. Prior to target onset, a behaviorally irrelevant cue was flashed at the same (congruent) or opposite (incongruent) location at various stimulusonset asynchrony (SOA) times. We measured eye and head movements and neck muscle electromyographic signals. Reaction times for the eye and head were highly correlated; both showed significantly shorter latencies (attentional facilitation) for congruent compared with incongruent cues at the two shortest SOAs and the opposite pattern (inhibition of return) at the longer SOAs, consistent with attentional modulation of a common eye-head gaze drive. Interestingly, we also found that the head latency relative to saccade onset was significantly shorter for congruent than that for incongruent cues. This suggests an effect of attention on the head separate from that on the eyes. I N T R O D U C T I O NUnder natural, head-unrestrained viewing conditions, saccades are typically composed of a combination of eye and head movements resulting in an overall gaze shift. The role of attention in saccadic eye movements has been studied extensively in head-restrained conditions. It has been established that saccade execution requires a shift of attention to the saccade goal (e.g., Deubel and Schneider 1996;Hoffman and Subramaniam 1995;Kowler et al. 1995;McPeek et al. 1999), indicating a close linkage between eye movements and attention. Such a linkage is also supported by a number of studies showing shared neural substrates for saccadic eye movement planning and attentional processing (e.g., Beauchamp et al.
