Mental imagery is a fundamental cognitive process of interest to basic scientists and clinical researchers. This study examined large-scale oscillatory brain activity in the alpha band (8-12 Hz) during language-driven mental imagery using dense-array EEG. Three experiments demonstrated relative increases in alpha amplitude: (1) during imagery prompted by words compared to fixation without image...

Imagery is an important feature of mental simulation, which is central to human cognitive functions from decision making to joint action to language production. Imagery is often used as a mental rehearsal strategy in areas of expertise, such as music, athletics and surgery, but also in movement rehabilitation. Individual imagery abilities may vary by general, modalityunspecific imagery capacity...

Over the last two decades, the number of studies on motor imagery in children has witnessed a large expansion. Most studies used the hand laterality judgment paradigm or the mental chronometry paradigm to examine motor imagery ability. The main objective of the current review is to collate these studies to provide a more comprehensive insight in children's motor imagery development and its age ...

It is commonly reported that transcranial magnetic stimulation (TMS) of the motor cortex during action observation and motor imagery results in increases in the amplitude of motor evoked potentials (MEPs) in muscles specific to the observed or imagined action. This study aimed to determine whether MEP amplitude was related to the motor imagery ability of participants. Participants were 15 healt...

Imagining motor acts is a cognitive task that engages parts of the executive motor system. While motor imagery has been intensively studied using neuroimaging techniques, most studies lack behavioral observations. Here, we used functional MRI to compare the functional neuroanatomy of motor execution and imagery using a task that objectively assesses imagery performance. With surface electromyog...

Objectives Drug related mental imagery is proposed to play a central role in addictive behaviour. However, little is known about such cognition or how it is pharmacologically modulated. Here, we test theoretical predictions of the 'elaborated intrusion' theory by comparing neutral with alcohol related mental imagery, and examine the effects of low dose alcohol on phenomenological aspects of thi...

The benefits of imagery use have been shown for athletes and neurological patients, but little is known about the benefits of motor and exercise imagery for older adults. Current research on movementrelated imagery is reviewed in this narrative article, with a focus on methods for estimating the ability to use motor and exercise imagery and the extent of their use. Recent investigations of moto...

For the inherent speckles in SAR imagery, the processing of object extraction becomes more difficult. Using the traditional target extraction arithmetic for optical imagery, we can not get ideal result on SAR imagery. Water object in SAR imagery represents as some continuous region with low lightness and strong speckle noise. The traditional method to extract low lightness object can be impleme...
