Eye movement and visuomotor arm movement deficits following mild closed head injury.
Based on increasing evidence that even mild closed head injury (CHI) can cause considerable neural damage throughout the brain, we hypothesized that mild CHI will disrupt the complex cerebral networks concerned with oculomotor and upper-limb visuomotor control, resulting in impaired motor function. Within 10 days following mild CHI (Glasgow Coma Scale 13-15, alteration of consciousness <20 min)...

متن کاملExecutive functioning following mild closed head injury.
This study was aimed to identify impaired attentional components in mild CHI patients. The CHI features taken into account were age (< or = 30 vs. > 30 years), loss of consciousness (yes vs. no), and time after injury (few days vs. some months). The groups tested were composed of 26 patients and 26 controls (matched for age, sex and education). Experiment 1 used a dual-task paradigm (Umiltà et ...
متن کاملMotor deficits and recovery during the first year following mild closed head injury.
OBJECTIVE This study examined motor impairments over 1 year following mild closed head injury (CHI). It is the first study to serially assess long-term oculomotor and upper-limb visuomotor function following mild head trauma. METHODS Thirty-seven patients with mild CHI and 37 matched controls were compared at 1 week, 3 months and 6 months and 31 available pairs at 12 months post-injury on mea...
متن کاملEye-Gaze and Arm-Movement Interaction
Eye-gaze in response to arm movment stimuli is modeled. It is demonstrated that the eyegaze response depends to a large degree on both instantaneous and past arm components movement as well as on past “long memory” of eye-gaze on a scale of about 0.1 second. The suggested class of models provide close fits. A long memory property in eye-gaze is validated from a certain spectral condition.
