Intact emotion-induced recognition bias in neuropsychological patients with executive control deficits.

In recognition memory tasks, emotionally negative words are judged more often as "old" relative to emotionally neutral words, suggesting a shift in response bias. We wondered whether this bias shift was due to the flexible regulation of executive control during memory retrieval. To address this question, we investigated individuals with high variability in executive control functions.

[Reduced contralateral preponderance of the movement-related potential during execution of self-initiated movements in acute prefrontal traumatic brain injury].

Objectives: An enhanced ipsilateral motor potential after prefrontal TBI is known. Our aim was to examine, whether this contributes to movement initiation or execution.

Methods: EEGs of 22 patients and 28 healthy controls were recorded.

Recovery of movement-related potentials in the temporal course after prefrontal traumatic brain injury: a follow-up study.

Objective: The movement-related potential (MRP) is an EEG measure related to self-initiated movements, consisting of the Bereitschaftspotential (BP), the negative slope, and the motor potential. Since in a former study the BP was reduced in acute prefrontal traumatic brain injury (TBI) patients, the present study examined the MRPs' course in follow-up examinations.

Methods: Right index finger MRPs of 22 patients with contusions of the prefrontal cortex were recorded 12, 26, and 52 weeks after TBI and compared to controls.

Impaired movement-related potentials in acute frontal traumatic brain injury.

Objective: Focal brain lesions due to traumatic brain injury (TBI) do not only lead to functional deficits in the lesion area, but also disturb the structurally intact neuronal network connected to the lesion site. Therefore we hypothesized dysfunctions of the cortical motor network after frontal TBI. The movement related potential (MRP) is an EEG component related to voluntary movement consisting of the Bereitschaftspotential (BP), the negative slope (NS), and the motor potential (MP).
