Abstract:
One way we keep track of our movements is by monitoring corollary discharges or internal copies of movement commands. This study tested a hypothesis that the pathway from superior colliculus (SC) to mediodorsal thalamus (MD) to frontal eye field (FEF) carries a corollary discharge about saccades made into the contralateral visual field. We inactivated the MD relay node with muscimol in monkeys and measured corollary discharge deficits using a double-step task: two sequential saccades were made to the locations of briefly flashed targets. To make second saccades correctly, monkeys had to intern

Abstract:
This thesis tests the theory that the sensory content of inner speech is constituted by corollary discharge. Corollary discharge is a signal generated by the motor system and is a “prediction” of the sensory consequences of the motor system’s actions. Corollary discharge normally functions in the nervous system to segregate self-caused sensations from externally-caused sensations. It does this, partially, by attenuating the nervous system’s response to self-caused sensations. This thesis argues that corollary discharge has been co-opted in humans to provide the sensory content of speech imager

Abstract:
Developing animals primarily receive two kinds of somatosensory input. One arises from stimulation in the external environment (“exafference”) and the other arises from self-produced movements (“reafference”), especially those associated with the myoclonic twitches during active sleep. Neural recordings have shown that exafferent and reafferent neural signals activate sensorimotor structures throughout the brain, but it is not known whether twitches are accompanied by corollary discharge that inform the nervous system that twitches are self-generated.

Abstract:
Nervous systems distinguish between self- and other-generated movements by monitoring discrepancies between planned and performed actions. To do so, when motor systems transmit motor commands to muscles, they simultaneously transmit motor copies, or corollary discharges, to sensory areas. There, corollary discharge signals are compared to sensory feedback arising from movements (reafference), which can result in gating of expected feedback. Curiously, in infant rats, twitches—which are self-generated movements produced exclusively and abundantly during active sleep (AS)—differ from wake-moveme

Abstract:
Considerable evidence indicates that visual sensitivity is reduced during saccadic eye movement. A central question has been whether saccadic suppression results from a non-visual central signal, or whether the obligate image motion that accompanies saccades is itself sufficient to mask vision. In the first of a series of experiments described here, the visual and non-visual effects of saccades were distinguished by measuring contrast sensitivity to luminance modulated low spatial frequency gratings, at 17 cd·m¯² and 0.17 cd·m¯², in saccade conditions and in conditions in which saccade-like im

Il mondo attorno a noi che percepiamo mediante la vista ci appare stabile nonostante le continue variazioni dell’input visivo prodotte dai movimenti oculari saccadici.

Secondo molti studi la stabilità visiva è imputabile ad un segnale detto “corollary discharge” (una copia del comando motorio) che informa anticipatamente le aree visive di alto livello (FEF, LIP) di una saccade imminente.

Abstract:
The understanding of the subjective experience of a visually stable world despite the occurrence of an observer's eye movements has been the focus of extensive research for over 20 years. These studies have revealed fundamental mechanisms such as anticipatory receptive field (RF) shifts and the saccadic suppression of stimulus displacements, yet there currently exists no single explanatory framework for these observations. We show that a previously presented neuro-computational model of peri-saccadic mislocalization accounts for the phenomenon of predictive remapping and for the observation of

Studies of cerebellum-like circuits in fish have demonstrated that synaptic plasticity shapes the motor corollary discharge responses of granule cells into highly-specific predictions of self- generated sensory input. However, the functional significance of such predictions, known as negative images, has not been directly tested. Here we provide evidence for improvements in neural coding and behavioral detection of prey-like stimuli due to negative images.

Abstract:
The outside-in framework inevitably poses the question: What comes between perception and action? The homunculus with its decision-making power produces unavoidable logical consequences from the separation of perception from action. I promote the alternative view that things and events in the world can acquire meaning only through brain-initiated actions. In this process, the brain builds a simplified, customized model of the world by encoding the relationships of events to each other. I introduce the concept of “corollary discharge,” the main physiological mechanism that grounds the sensory input to make it an experience. This is a comparator mechanism that allows the brain to examine the relationship between a true change in the sensory input and a change due to self-initiated movement of the sensors.

Abstract:
This chapter summarizes the properties and neural substrate of smooth eye tracking movements, including visual fixation, smooth pursuit, the ocular following response (OFR), and optokinetic nystagmus (OKN). Fixational eye movements, including microsaccades and drifts, and the role of the OFR in stabilizing gaze are discussed. The properties of pursuit, OFR, and OKN are summarized, including anticipation, prediction, and target selection. The ability of pursuit adaptation to respond to new visual demands is reviewed. Pertinent cortical areas (MT+) and their projections to brainstem and cerebellum are discussed, as well as the accessory optic pathway, and nucleus of the optic tract. Current models for smooth pursuit that incorporate efference copy (corollary discharge), prediction, and Bayesian operators are summarized. Clinical and laboratory evaluation of fixation and visual tracking are reviewed, and the pathogenesis of disorders of these movements discussed, including latent nystagmus accompanying failure to develop binocular vision and infantile nystagmus syndrome.

Full text
Abstract:
This chapter describes how perceptual and navigation functions can become disengaged from their dependence on the external world. The key physiological mechanism that allows this “internalization” process is the corollary discharge system, which can interpret the activity of action circuits even in the absence of overt movement and sensory feedback from muscles. Within such an internalized world, brain networks can anticipate the consequences of imagined actions without the need to act them out. Instead the outcomes can be tested against previously acquired knowledge, which creates new knowledge entirely through self-organized brain activity. Neuronal circuits can perform both input-dependent and input-disengaged operations. Even simple brains of small animals have elements of internal operations (“cognition”). As the complexity of neural networks increases in larger brains, the share and efficacy of internalized computation also increases and can predict consequences of the brain’s actions over longer time scales and in more complex environments.

Abstract:
This chapter explains why and how tracking of objects moving relative to an observer, and visual optic flow navigation of an observer relative to the world, are controlled by complementary cortical streams through MT<sup>-</sup>-MSTv and MT<sup>+</sup>-MSTd, respectively. Target tracking uses subtractive processing of visual signals to extract an object’s bounding contours as they move relative to a background. Navigation by optic flow uses additive processing of an entire scene to derive properties such as an observer’s heading, or self-motion direction, as it moves through the scene. The chapter explains how the aperture problem for computing heading in natural scenes is solved in MT<sup>+</sup>-MSTd using a hierarchy of processing stages that is homologous to the one that solves the aperture problem for computing motion direction in MT<sup>-</sup>-MSTv. Both use feedback which obeys the ART Matching Rule to select final perceptual representations and choices. Compensation for eye movements using corollary discharge, or efference copy, signals enables an accurate heading direction to be computed. Neurophysiological data about heading direction are quantitatively simulated. Log polar processing by the cortical magnification factor simplifies computation of motion direction. This space-variant processing is maximally position invariant due to the cortical choice of network parameters. How smooth pursuit occurs, and is maintained during accurate tracking, is explained. Goal approach and obstacle avoidance are explained by attractor-repeller networks. Gaussian peak shifts control steering to a goal, as well as peak shift and behavioral contrast during operant conditioning, and vector decomposition during the relative motion of object parts.
