Recruitment & Eligibility

Status: Recruiting

Sex: Not specified

Target Recruitment: 84

Inclusion Criteria

- age 18 years and higher and mentally competent;
- a clinical indication for resection of a tumor or other lesion (e.g. focus of
epileptic seizures);
- a clinical indication for awake surgery (or if applicable, for a full asleep
procedure);

Exclusion Criteria

- indication for longer than average (225 min) duration of the procedure
(estimation by the neurosurgeon);
- the neurosurgeon decides that a certain patient is not eligible to
participate in the study (e.g. for medical or surgical reasons);
- planned trepanation too far away for grid placement on a target location
(evaluation by the neurosurgeon and researcher combined);
- reported function loss that prohibits the accurate performance of the
required tasks;
Other exclusion criteria refer to specific parts of the study and do not affect
the overall exclusion of the study. These are for example exclusion criteria
for fMRI research, which include pregnancy, claustrophobia and presence of
metals in the body
