This experiment was designed to investigate the neural network engaged by the perception of human movements using positron emission tomography. Perception of meaningful and of meaningless hand actions without any purpose was contrasted with the perception of the same kind of stimuli with the goal to imitate them later. A condition that consisted of the perception of stationary hands served as a baseline level. Perception of meaningful actions and meaningless actions without any aim was… 

The effects of learning and intention on the neural network involved in the perception of meaningless actions.

The results provide evidence for both an effect of the visuomotor learning level and of the subject's intention on the neural network involved during the perception of human meaningless actions.

Neural Circuits Involved in the Recognition of Actions Performed by Nonconspecifics: An fMRI Study

Assessment of cortical areas active during the observation of mouth actions performed by humans and by individuals belonging to other species suggests that actions made by other individuals may be recognized through different mechanisms.

Does the End Justify the Means? A PET Exploration of the Mechanisms Involved in Human Imitation

The results suggest that for normally functioning adults, imitating a gesture activates neural processing of the intention (or goal) underlying the observed action.

Movement and Mind: A Functional Imaging Study of Perception and Interpretation of Complex Intentional Movement Patterns

A functional neuroimaging study with positron emission tomography in which six healthy adult volunteers were scanned while watching silent computer-presented animations showed increased activation in association with mental state attribution in four main regions: medial prefrontal cortex, temporoparietal junction, basal temporal regions, and extrastriate cortex.

The neural substrates of biological motion perception: an fMRI study.

The results suggest that a region of the lingual gyrus within VP is involved in higher-order processing of motion information, and this region was replicated in a second experiment that also mapped retinotopic visual areas in three subjects.

An fMRI study of imitation: action representation and body schema




Specific Involvement of Human Parietal Systems and the Amygdala in the Perception of Biological Motion

The results demonstrated that the perception of scripts of goal-directed hand action implicates the cortex in the intraparietal sulcus and the caudal part of the superior temporal sulcus, both in the left hemisphere.

Preparation for reaching: a PET study of the participating structures in the human brain.

No activations were seen in the motor cortices, indicating that reaching is a task which does not require substantial preparatory activity of motor cortice prior to the go signal.

Brain activity during observation of actions. Influence of action content and subject's strategy.

The pattern of brain activation during observation of actions is dependent both on the nature of the required executive processing and the type of the extrinsic properties of the action presented.

Use of implicit motor imagery for visual shape discrimination as revealed by PET

It is concluded that mental imagery is realized at intermediate-to-high order, modality-specific cortical systems, but does not require primary cortex and is not constrained to the perceptual systems of the presented stimuli.

Functional anatomy of the mental representation of upper extremity movements in healthy subjects.

Investigating differences in the distribution of relative regional cerebral blood flow during motor imagery and execution of a joy-stick movement with positron emission tomography suggested that imagined movements can be viewed as a special form of "motor behavior' that activate areas associated heretofore with selection of actions and multisensory integration.

Possible involvement of primary motor cortex in mentally simulated movement: a functional magnetic resonance imaging study.

Functional magnetic resonance imaging signals measured in normal right-handed subjects during actual and mental execution of a finger-to-thumb opposition task with either the right or the left hand support the hypothesis that motor imagery involves virtually all stages of motor control.

Intact "biological motion" and "structure from motion" perception in a patient with impaired motion mechanisms: a case study.

The patient with bilateral lesions involving the posterior visual pathways, affecting the lateral parietal-temporal-occipital cortex and the underlying white matter was able to identify actions from the evolving pattern of dots placed at the joints of a human actor as well as discriminating three-dimensional structure of a cylinder from motion in a dynamic random-dot field.

Action recognition in the premotor cortex.

It is proposed that mirror neurons form a system for matching observation and execution of motor actions, similar to that of mirror neurons exists in humans and could be involved in recognition of actions as well as phonetic gestures.
