“…Evidence from behavioural and neuroimaging studies suggests modality-specific as well as multimodal representations. For example, imagining the tactile features of an object can accelerate reaction times to tactile, but not to auditory, stimuli, suggesting modality-specific representation [47]. Moreover, somatotopic specific activations in SI can be observed during tactile imagery for different body parts [48].…”

The somatosensory system is important for many functions, such as tactile recognition, the perception of our body, and motor actions. We present a comprehensive review of the human and animal literature on somatosensory processing over the past 10 years and evaluate how well existing models can accommodate the new observations. Based on these observations and a survey of the brain structures involved in somatosensation, we suggest that a new model is needed that describes multiple networks involved in separate subfunctions. These networks are highly interconnected and often multimodal in nature. The model includes basic somatosensory processing and five higherorder networks involved in haptic object recognition and memory, body perception, body ownership, affective processing, and action. The Role and Early Theories of Somatosensory ProcessingSomatosensory processing is central to life; a touch on the shoulder, a soft stroke on the handboth can say more that words. We use it to be aware of the parts that belong to our body, it has an important social function, and it is crucial for socioemotional development. It is also important for almost every activity during our daily life and forms the basis of all of our motor actions. Furthermore, somatosensory processing allows us to recognize with ease different objects based on touch alone (haptic object recognition; see Glossary). Thus, the processing of touch, temperature, pain, and proprioception are important for survival, for efficient interaction with the environment, and for emotional and social functioning.

“…For example, the pleasantness of caress and corresponding touch-evoked activation in S1 are enhanced when the apparent (implied) gender and attractiveness or the caresser is manipulated (Gazzola et al 2012). Thinking about touch can also selectively facilitate response time to tactile stimuli (Anema et al 2012). …”

Common coding and dynamic interactions between observed, imagined, and experienced motor and somatosensory activity

Motor imagery and perception- considered generally as forms of motor simulation- share overlapping neural representations with motor production. While much research has focused on the extent of this “common coding,” less attention has been paid to how these overlapping representations interact. How do imagined, observed, or produced actions influence one another, and how do we maintain control over our perception and behavior? In the first part of this review we describe interactions between motor production and motor simulation, and explore apparent regulatory mechanisms that balance these processes. Next, we consider the somatosensory system. Numerous studies now support a “sensory mirror system” comprised of neural representations activated by either afferent sensation or vicarious sensation. In the second part of this review we summarize evidence for shared representations of sensation and sensory simulation (including imagery and observed sensation), and suggest that similar interactions and regulation of simulation occur in the somatosensory domain as in the motor domain. We suggest that both motor and somatosensory simulations are flexibly regulated to support simulations congruent with our sensorimotor experience and goals and suppress or separate the influence of those that are not. These regulatory mechanisms are frequently revealed by cases of brain injury but can also be employed to facilitate sensorimotor rehabilitation.

“…Mental imagery allows us to re-experience information recalled from memory across multiple sensory modalities ( Kosslyn et al, 2001; Anema et al, 2012 ). Mental imagery and perception interact, such that imagining visual information can influence detection of visual targets in the environment ( Farah, 1985; Craver-Lemley and Arterberry, 2001; Pearson et al, 2008; Anema et al, 2012 ). This is likely due to overlapping neuronal substrates engaged during perception and imagery across different sensory modalities ( Kosslyn et al, 2001 ), ( Kosslyn et al, 2001; Yoo et al, 2003 ).…”
