S3-3 Sensorimotor Integration - Forward Model II (3)

Introduction to Sensorimotor Transformations

• Defines sensorimotor transformations and emphasizes the role of perceptual-motor integration in behavior.

• Highlights forward and inverse models in sensorimotor control.

Internal Models in Sensorimotor Control

• Discusses internal models and their function in actions and sensory feedback.

• Explains predictive capabilities and internal feedback loops.

Study Objectives

• Key objectives include understanding forward and inverse models, internal feedback mechanisms, and supporting experimental evidence.

Sensorimotor Control Loop

• Components include the desired versus actual motor state, the role of the Motor Controller, Sensory Afference, and Comparator, and the importance of feedback processes.

Sensory Confirmation

• Mechanisms to distinguish between external and self-generated signals and insights into action agency.

Predicted Efference and Feedback

• Discusses efference copy and sensory discrepancies between self-generated and external stimuli.

Experimental Insights

• Overview of experiments on tactile stimulus responses, sensory ratings, and trajectory perturbations.

• Analysis of findings related to somatosensory perception and force matching experiments.

Neurological Insights

• Insights into the cerebellum's role in sensory predictions and error corrections, along with learning mechanisms in response to motion.

Impacts on Cognitive Disorders

• Examines how cognitive disorders like schizophrenia affect movement awareness and misattribution of self-generated actions.

• Discusses experimental designs aimed at understanding action attribution and sensory feedback manipulations.
