Goal contagion, the tendency to adopt others' goals, significantly impacts cognitive processes, which gains particular importance in the emerging field of human-robot interactions. The present study explored how observing human versus robotic actions affects preference and memory. Series of objects undergoing either human or robotic grasping actions together with static (no action) objects were presented, while participants indicated their preference for each object.

The aesthetic values that individuals place on visual images are formed and shaped over a lifetime. However, whether the formation of visual aesthetic value is solely influenced by environmental exposure is still a matter of debate. Here, we considered differences in aesthetic value emerging across three visual domains: abstract images, scenes, and faces.

Article Synopsis
  • Recent research indicates that viewing art activates the motor cortex in the brain, leading to two competing hypotheses: the emotional reaction hypothesis and the embodied aesthetic hypothesis.
  • A study tested these hypotheses using transcranial magnetic stimulation to measure motor responses while participants viewed different art styles, specifically pointillist and brushstroke canvases, as well as control photographs.
  • Results showed that while early motor activation did not support the emotional reaction hypothesis, later responses indicated greater motor activation for brushstroke canvases, aligning with the embodied aesthetic hypothesis, suggesting that simulating the artist's movements is key to experiencing art.

Article Synopsis
  • The study investigates how the inferior parietal lobe (IPL) contributes to distinguishing our own actions from those of others, focusing on action authorship.
  • The researchers used theta-burst stimulation (TBS) to manipulate the left IPL's activity before participants experienced the rubber hand illusion, where they mistakenly felt others' movements as their own.
  • Findings indicated that normal IPL function helps differentiate self-attributed actions from others', as disrupting IPL activity led to a failure in this differentiation, enhancing understanding of the IPL's role in social perception and action control.

Numerous studies corroborated the idea that the sound of familiar motor acts triggers a muscle-specific replica of the perceived actions in the listener's brain. We recently contradicted this conclusion by demonstrating that the representation of newly-learned action-related sounds is not somatotopically organised but rather it corresponds to the goal a particular action aims to achieve. In the present study, we aimed at reconciling these results.

Article Synopsis
  • Observing someone reach for an object increases our liking for that object, suggesting a link between action observation and how we value items.
  • Researchers conducted a study using continuous theta burst stimulation (cTBS) on the left inferior parietal lobule (IPL) to explore this connection, as the IPL is associated with both action observation and tool use.
  • The findings indicated that participants showed higher preference ratings for tools that were reached for by others after stimulation, reinforcing the idea that our preferences are shaped by the actions we observe, supporting embodied cognition theories.

Article Synopsis
  • The study examines how flexible the mirror neuron mechanism is concerning experiences and its impact on social cognition.
  • It investigates the effects of mirror and counter-mirror trainings on auditory motor-evoked potentials (MEPs) related to sound perception.
  • Findings indicate that once mirror MEPs are established, they resist change from counter-mirror experiences, suggesting that this stability is beneficial for understanding social interactions.

Article Synopsis
  • Neuroimaging techniques have improved our understanding of how the brain responds to aesthetic experiences in art.
  • Researchers are focusing on the dorsolateral and orbitofrontal cortices as key areas involved in aesthetic appreciation.
  • The paper argues against the idea that these brain regions play a central role in determining aesthetic preferences, suggesting the need for further exploration of their connections and functions.

The creation of an artwork requires motor activity. To what extent is art appreciation divorced from that activity and to what extent is it linked to it? That is the question which we set out to answer. We presented participants with pointillist-style paintings featuring discernible brushstrokes and asked them to rate their liking of each canvas when it was preceded by images priming a motor act either compatible or incompatible with the simulation of the artist's movements.

Action observation activates the observer's motor system. These motor resonance responses are automatic and triggered even when the action is only implied in static snapshots. However, it is largely unknown whether an action needs to be consciously perceived to trigger motor resonance.

Joint actions require the integration of simultaneous self- and other-related behaviour. Here, we investigated whether this function is underpinned by motor simulation, that is the capacity to represent a perceived action in terms of the neural resources required to execute it. This was tested in a music performance experiment wherein on-line brain stimulation (double-pulse transcranial magnetic stimulation, dTMS) was employed to interfere with motor simulation.

Article Synopsis
  • The study examines the automatic tendency of humans to imitate gestures and debates whether this imitation is truly independent from spatial compatibility.
  • Evidence from the research indicates that automatic imitation, or 'imitative compatibility,' operates separately from spatial factors.
  • Using double-pulse transcranial magnetic stimulation on the parietal opercula, the study found that disrupting this brain region reduced imitative compatibility but did not affect spatial compatibility, highlighting their independence.

Article Synopsis
  • Research on how brains interpret motion typically focuses on adults and monkeys, suggesting a bias toward familiar human actions in the motor system.
  • This study investigates 4-month-old infants using functional near-infrared spectroscopy to observe their brain responses to human-like versus robot-like movements.
  • Results show infants' premotor cortex is more activated by robot-like motion, indicating an ability to engage with novel movement patterns, while their temporal cortex integrates form and motion, similar to adult brain responses.

The capacity to distinguish between one's own and others' behavior is a cognitive prerequisite for successful joint action. We employed a musical joint action task to investigate how the brain achieves this distinction. Pianists performed the right-hand part of piano pieces, previously learned bimanually, while the complementary left-hand part either was not executed or was (believed to be) played by a co-performer.

The field of neuroaesthetics attracts attention from neuroscientists and artists interested in the neural underpinnings of esthetic experience. Though less studied than the neuroaesthetics of visual art, dance neuroaesthetics is a particularly rich subfield to explore, as it is informed not only by research on the neurobiology of aesthetics, but also by an extensive literature on how action experience shapes perception. Moreover, it is ideally suited to explore the embodied simulation account of esthetic experience, which posits that activation within sensorimotor areas of the brain, known as the action observation network (AON), is a critical element of the esthetic response.

Article Synopsis
  • Our brain can recognize actions through sound alone by simulating the movement associated with those sounds, even without visual cues.
  • Previous research showed that familiar motor actions activate specific areas in our motor cortex, but this study focused on how new action-related sounds can evoke similar motor responses.
  • The findings indicate that passive listening to these newly learned sounds activates a motor representation that is linked to the intention of the action rather than the muscle movements themselves, highlighting a complex relationship between auditory perception and intended action goals.

Background: Peripheral homonymous scotomas beyond 30° from fixation are rare. The paucity of publications describing such visual field defects might be attributed to various factors, including the absence of severe symptoms, routine visual field assessment restricted to the central 30° with automated perimetry, and the collateral circulation to the occipital cortex. The aim of this study was to correlate the brain lesions and perimetric findings in 2 unusual cases of peripheral homonymous scotomas, with the anatomic location of the optic radiation and primary visual cortex.

A case of partial recovery after stroke and its associated brain reorganization in a chronic patient after combined brain computer interface (BCI) training and physiotherapy is presented. A multimodal neuroimaging approach based on fMRI and diffusion tensor imaging was used to investigate plasticity of the brain motor system in parallel with longitudinal clinical assessments. A convergent association between functional and structural data in the ipsilesional premotor areas was observed.

Visual extinction is an intriguing defect of awareness in stroke patients, referring to the unsuccessful perception of contralesional events under conditions of competition. Previous studies have investigated the cortical and subcortical brain structures that, when damaged or inactivated, provoke visual extinction. The present experiment asked how lesions of subcortical structures may contribute to the appearance of visual extinction.

Brain damage may induce a dysfunction of upright body position termed "pusher syndrome". Patients with such disorder suffer from an alteration of their sense of body verticality. They experience their body as oriented upright when actually tilted nearly 20 degrees to the ipsilesional side.

Previous statistical voxelwise lesion-behavior mapping (VLBM) studies have demonstrated that spatial neglect is associated with cortical and subcortical gray matter damage. However, it has also been suggested that the disorder may result from white matter injury. Our aim was to investigate the white matter connectivity in a large sample of 140 stroke patients.
