Following the logic of lie detection and the assessment of criminal sceneries 40 mg strattera free shipping, a set of 40 questions was constructed (a BCI questioning system) and formulated in Copyright © 2005 CRC Press LLC Spanish so that the decisive and meaning-carrying word always arrived at the end of the question and each question was formulated in an affirmative or negative grammatical form purchase 18 mg strattera. Questions of vital importance for the patient were mixed with neutral questions such as “The capital of Peru is Lima,” “The capital of Peru is Bogota,” “The capital of Peru is Santiago,” and “The capital of Peru is Asunciòn. In addition, the television screen was brightly lit during negativity and darkened during positivity, providing the patient with continuous visual feedback of his ongoing cortical polarization even with closed eyes. The data show that the patient was able to answer these questions at a stabile and significant level. In addition, copy spelling of several words was possible, but free spelling could not be achieved because of the high variation of correct performance related to motiva- tional and behavioral effects. The training of this patient continues and progress will be reported in the future. However, the analysis of the data during the 3-week training session showed that at least “yes” or “no” communication on a high level of per- formance is possible with the completely locked-in patient. It was demon- strated that this is not an impossible task, when patients suffering from advanced ALS acquired the ability to operate a spelling device by regulating their SCPs82,95 (see also Section 14. In some cases, however, even after several months of practice, no vol- untary control of SCPs could be attained. Therefore, the question arose whether it was possible for such a patient to learn to control specific frequency components of the sensorimotor EEG by using an imagery strategy. Regular training sessions for the patient were carried out at a clinic for assisted communications over a period of 22 weeks, supervised from the technical laboratory with the help of a “telemonitoring system. The EEG signal (5–30 Hz) used for classification or feedback was recorded from one bipolar channel over the left sensorimotor cortex and sampled at 128 Hz. To generate the feedback based on oscillatory components of the ongoing EEG, two approaches were used: (1) direct band power feedback (20–30 Hz), and (2) feedback calculated by a linear discriminant classifier, which was developed to discriminate between two brain states. The discriminating feature was a prominent, long-lasting desynchronization (ERD) of higher beta band components during imag- ination of right-hand movement, which was not visible during other imagination tasks. STEP 2: FREE TRAINING In order to enhance the selected EEG components, a so-called “free training” was performed, where the band power (20–30 Hz) was continuously averaged over 4 sec and displayed on the screen as a vertically moving feedback dot (“cursor”). The patient was advised that imagination of right-hand movement moved the cursor downward (band power decrease, ERD). Relaxation, in contrast, either moved the cursor upward or caused it to remain in the center of the screen. Copyright © 2005 CRC Press LLC STEP 3: CUE-GUIDED TRAINING The next step was to present visual cue stimuli (an arrow pointing up or down; standard BCI paradigm) and to ask the patient to move the feedback dot (cursor) in the indicated direction. The cursor position, based on the actual band power, was shown for a 4-sec time interval after cue presentation. STEP 4: LETTER SELECTION TASK Instead of the cue stimulus, two letters were presented, one near the top, the other near the bottom of the monitor. To select the upper letter, an increase in band power had to be produced by relaxing, whereas selection of the lower letter was achieved by motor imagery leading to band power decrease. STEP 5: COPY SPELLING In the final step the patient was confronted with a modified version of the so-called virtual keyboard76 (see Section 14. Instead of single characters, a predefined set of letters, split into two equally sized subsets, was presented at the top and at the bottom of the monitor, respectively. When the patient was able to select the subset that contained the target letter, this subset was again split into two parts. This was continued until the patient selected the desired letter and, in a further step, confirmed this selection. During the first weeks of training in copy spelling, only correct selections were accepted by the system; false selections were measured for off-line analyses. This “error ignoring” mode was introduced in order to avoid the conse- quences of a wrong selection during training. The on-line performance of letter selection, quantified as percentages of correct responses according to the classifier-based discrimination, indicated a significant learning progress from the first ten sessions (61. At the end of the reported training procedure, this patient was able to produce voluntarily two distinct EEG patterns, associated with motor imagery versus intended relaxing, and to use this imagery strategy for BCI control. With the achieved level of 70% accuracy in letter selection training, verbal communication was possible by means of a spelling device. This allowed the patient to write with a rate of approximately one letter per minute. He participated in BCI training with different types of motor imagery in order to check whether he was able to operate an orthosis or functional electrical stimulation (FES).
