PET was used to map brain regions that are associated with the observation of meaningful and meaningless hand actions. Subjects were scanned under four conditions which consisted of visually presented actions. In each of the four experimental conditions, they were instructed to watch the actions with one of two aims: to be able to recognize or to imitate them later. We found that differences in the meaning of the action, irrespective of the strategy used during observation, lead to different… 

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.

Action Sentences Activate Sensory Motor Regions in the Brain Independently of Their Status of Reality

The results showed that action sentences elicited stronger activations than visual sentences in the SMA, extending to the primary motor area, as well as in regions generally associated with the planning and understanding of actions, which support the claim that embodied representations of linguistic meaning are important even in abstract linguistic contexts.

The role of the extrastriate body area in action perception

It is proposed that the EBA plays a unique role in the perception of action, by representing the static structure, rather than dynamic aspects, of the human form by adapting its response when succeeding images depict relatively similar postures.

Investigation of the neural network engaged by the perception of human movements using positron emission tomography found that meaningful and meaningless actions shared almost the same network when the aim of the perception was to imitate them later.

Research report P cortex in observing erroneous action: an fMRI study

FMRI was used to investigate if paying attention to the two observable action components, objects and movements, modulates premotor activation during the observation of actions, and it was suggested that the analysis of categorical information, like objects, and that of coordinate information,like movements, are pronounced in different hemispheres.



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.

Discrete Cortical Regions Associated with Knowledge of Color and Knowledge of Action

The areas of the brain that mediate knowledge about objects were investigated by measuring changes in regional cerebral blood flow using positron emission tomography (PET), and data suggest that object knowledge is organized as a distributed system in which the attributes of an object are stored close to the regions of the cortex that mediated perception of those attributes.

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.

Visual pathways for object-oriented action and object recognition: functional anatomy with PET.

Object-oriented action and object recognition activate a common posterior parietal area, suggesting that some kind of within-object spatial analysis was processed by this area whatever the goal of the task.

Premotor cortex and the recognition of motor actions.

The Mental Representation of Hand Movements After Parietal Cortex Damage

Patients with lesions restricted to the parietal cortex were found to be impaired selectively at predicting, through mental imagery, the time necessary to perform differentiated finger movements and visually guided pointing gestures, in comparison to normal individuals and to a patient with damage to the primary motor area.

Neural correlates of category-specific knowledge

It is found that naming pictures of animals and tools was associated with bilateral activation of the ventral temporal lobes and Broca's area, and the brain regions active during object identification are dependent, in part, on the intrinsic properties of the object presented.

Frameworks of analysis for the neural representation of animate objects and actions.

This work has investigated the sensitivity of cells in the temporal cortex to different viewing conditions to determine the frame(s) of reference utilized in processing and found goal-centred sensitivity to interaction allowed the cells to be selectively activated in situations where human subjects would attribute causal and intentional relationships.

Mapping motor representations with positron emission tomography

Brain activity was mapped in normal subjects during passive obser-vation of the movements of an 'alien' hand and while imagining grasping objects with their own hand to support the notion that motor learning during observation of movements and mental practice involves rehearsal of neural pathways related to cognitive stages of motor control.
