“…The differences between pre-and posttraining responses started at 300 -600 msec after picture presentation and continued for 200 -700 msec. Focal brain lesion studies have suggested that lesions in the left inferior parietal lobe lead to disturbances in spatial tasks (Mattingley, Husain, Rorden, Kennard, & Driver, 1998;Vallar, Sterzi, Bottini, Cappa, & Rusconi, 1990), in acquisition and retrieval of information from episodic memory (Shallice & Vallar, 1990;Shallice & Warrington, 1980), and in the phonological storage component of short-term memory ( Vallar, Di Betta, & Silveri, 1997). Aphasiological studies have indicated that left inferior parietal lesions quite often lead to conduction aphasia, in which phonological output problems are remarkable, or to anomic aphasia (cf.…”

Abstract& We describe a study where a specific treatment method for word-finding difficulty (so-called contextual priming technique, which combines massive repetition priming with semantic priming) was applied with three chronic left hemispheredamaged aphasics. Both before and after treatment, which focused on naming of a series of pictures, naming-related brain activity was measured by magnetoencephalography (MEG). Due to its excellent temporal resolution and good spatial resolution, we were able to track treatment-induced changes in cortical activity. All three subjects showed improved naming of the trained items. In all subjects, a single source area, located in the left inferior parietal lobe, close to the lesioned area, displayed statistically significant training-induced changes. This effect was of long latency as it started 300 -600 msec after picture presentation. The change in activation was specific to training, as it could not be accounted for by variation of cortical dynamics associated with increased proportion of correct answers. Our interpretation is that the training effect reflects more effective phonological encoding and storage of the trained items through the engagement of a left hemispheric word-learning system. This is in line with recent functional imaging studies, which have linked left inferior parietal lobe activity to the phonological storage component of the verbal working memory, as well as with theoretical arguments stating that the primary role of the phonological loop is to acquire new words. Finally, the MEG results showed no evidence of increased right hemisphere participation following training, supporting the view that restoration of language-related networks in the damaged left hemisphere is crucial for anomia recovery. &

“…A number of studies have investigated this possibility. Rehabilitation with vestibular stimulation (Cappa, Sterzi, Vallar, & Bisiach, 1987;Vallar, Sterzi, Bottini, Cappa, & Rusconi, 1990), or with optokinetic nistagmus (Pizzamiglio, Frasca, Guariglia, Incoccia, & Antonucci, 1990), both of which produce a re¯ex-ive eye deviation toward the neglected side, yield a reduction of neglect. However, this bene®t is short-lived.…”

The ability to image the human brain has provided a new perspective for neuropsychologists in their efforts to understand, diagnose, and treat insults to the human brain that might occur as the result of stroke, tumor, traumatic injury, degenerative disease, or errors in development. These new ®ndings are the major theme of this special issue. In our article, we consider brain networks that carry out the functions of attention. We outline several such networks that have been studied in normal and pathological states. These include networks for orienting to sensory stimuli, for maintaining the alert state, and for orchestrating volitional control.There is evidence that these networks have a certain degree of anatomical and functional independence, but that they also interact in many practical situations. Damage to each of these networks, irrespective of the source, produces distinctive neuropsychological de®cits. We consider the links between the etiology of the injury and changes in cognition and behavior and examine the role of brain imaging in the study of rehabilitation.

“…In light of these figures, it is perhaps not surprising that, over the last 50 years, an increasing number of cognitive rehabilitation techniques have been developed to improve the recovery of neglect patients (for a recent review see Kerkhoff & Schenk, 2012), such as visual scanning training (e.g., Antonucci et al, 1995;Kerkhoff, 1998;Lawson, 1962;Piccardi, Nico, Bureca, Matano, & Guariglia, 2006;Pizzamiglio et al, 1992), limb activation training (e.g., Brunila, Lincoln, Lindell, Tenovuo, & Hamalainen, 2002;, 1994Robertson, Hogg, & McMillan, 1998a;Robertson, McMillan, MacLeod, Edgeworth, & Brock, 2002;Robertson, North, & Geggie, 1992;Samuel et al, 2000), sustained attention training (e.g., Robertson, Tegnér, Tham, Lo, & Nimmo-Smith, 1995;Robertson, Mattingley, Rorden, & Driver, 1998b;Thimm, Fink, Küst, Karbe, & Sturm, 2006), prism adaptation (e.g., Frassinetti, Angeli, Meneghello, Avanzi, & Ladavas, 2002; Jacquin-Courtois, Rode, Pisella, Boisson, & Rossetti, 2008;Rossetti et al, 1998;Vaes et al, 2016; for a recent review see Newport & Schenk, 2012), neck muscle vibration (e.g., Karnath, 1994;Karnath, Christ, & Hartje, 1993;Schindler & Kerkhoff, 2004;Schindler, Kerkhoff, Karnath, Keller, & Goldenberg, 2002), caloric (e.g., Cappa, Sterzi, Vallar, & Bisiach, 1987;Rubens, 1985;Vallar, Sterzi, Bottini, Cappa, & Rusconi, 1990) and optokinetic stimulation (e.g., Bisiach, Pizzamiglio, Nico, & Antonucci, 1996;Karnath, 1996;Kerkhoff, Schindler, Keller, & Marquardt, 1999…”

Hemispatial neglect is a severe cognitive condition frequently observed after a stroke, associated with unawareness of one side of space, disability and poor long-term outcome. Visuomotor feedback training (VFT) is a neglect rehabilitation technique that involves a simple, inexpensive and feasible training of grasping-to-lift rods at the centre. We compared the immediate and long-term effects of VFT vs. a control training when delivered in a home-based setting. Twenty participants were randomly allocated to an intervention (who received VFT) or a control group (n = 10 each). Training was delivered for two sessions by an experimenter and then patients self-administered it for 10 sessions over two weeks. Outcome measures included the Behavioural Inattention Test (BIT), line bisection, Balloons Test, Landmark task, room description task, subjective straight-ahead pointing task and the Stroke Impact Scale. The measures were obtained before, immediately after the training sessions and after four-months post-training. Significantly greater short and longterm improvements were obtained after VFT when compared to control training in line bisection, BIT and spatial bias in cancellation. VFT also produced improvements on activities of daily living. We conclude that VFT is a feasible, effective, homebased rehabilitation method for neglect patients that warrants further investigation with well-designed randomised controlled trials on a large sample of patients.
