The clinical ex- creasingly depends on the kind of surgical procedures and approaches which need to be chosen. This 6-month rule may be overruled by the possibilities of less invasive sur- gical procedures which allow a faster recuperation and cause less surgical trauma. Many of the criteria are used to make a surgical indi- cation cannot be handled rigidly and must be weighted in an interdisciplinary decision-making process. For exam- ple, there is substantial debate over what is exactly an un- stable spine, and consequently there may be patients who are definitely overtreated with all the technical options available today on the base of an obscure understanding of instability. For example, applying the Denis classifica- tion for traumatic thoracolumbar fractures may not be ap- propriate as indication basis for surgical indications. Irradiation which preceding surgery has a significantly higher surgery which should be applied to the metastatic spine complication rate [13, 16, 32, 50, 51].

Each oriented stimulus was presented for 3 s 30 mg nimotop otc spasms right abdomen, followed by ap- proximately 3 s of a screen uniformly lit at the background intensity order 30mg nimotop spasms jaw. Three hundred trials were performed, giving twenty-five repeats for each orientation. The orientation for each trial was randomly assigned through a shu¿ing algo- rithm, thereby ensuring that each orientation was tested an equal number of times. The same twelve orientations were tested, but each trial consisted of 64 s of stimulation with a bar, resulting in four passes of the bar, followed by approximately 4 s of a uniformly lit screen at the background inten- sity. Only forty-eight trials were performed, representing four trials at each orienta- tion. Again, the orientation for each trial was selected by a shu¿ing algorithm. Imaging 2-D Neural Activity Patterns 47 The checkerboard pattern consisted of a number of 1:1 Â 1:1-degree squares. Using a pseudorandom number generator, each square was set to one of three inten- sities: white with 15% probability, o¤ with 15% probability, or background with 70% probability. This allowed the entire checkerboard to be shifted both vertically and horizontally by 0. A new checkerboard with a new logical screen o¤set was displayed at a rate of 25 Hz. For all stimuli, the di¤erence between the most intense white and darkest black was selected to give a 50% contrast, with the background intensity set half- way through the intensity range. Data Analysis The optimal orientation was calculated from the drifting sine wave gratings by the method described by Orban (1991). For each orientation tested, a peristimulus time histogram (PSTH) was calculated for the activity recorded on each electrode. The optimal orientation for each multiunit was selected as the orientation giving the largest firing rate for that unit. The recently introduced method of electrophysiological imaging (Diogo et al. In this method, one interpolates activity-level maps for each of the conditions tested; here it was the orientation of a drifting sine wave grating. The condition maps are then combined using the same methods used by the optical imaging community to give a single response map. Their finding that the map of activity for a single condi- tion is relatively smooth supports the validity of interpolating the condition maps. A reverse correlation method was used to estimate the receptive field size and position from the random checkerboard stimulus (Jones and Palmer, 1987; Eckhorn et al. In brief, this method performs a cross-correlation between the occur- rence of a spike and the state of each of the pixels of the computer monitor. Since there is a delay between changing the visual stimulus and the resulting spike, the cross-correlation is typically only examined over a period of 100–20 ms before the spike. After normalization, the result is a three-dimensional array of t-scores, with two of the dimensions representing the vertical and horizontal extent of the computer monitor and the third the latency from the state of the display to a spike. Since the result is presented as a t-score, typically out of a distribution with a very large num- ber of degrees of freedom, the magnitude of the cross-correlation has units of stan- dard deviations. A more complete description of the statistical interpretation of the cross-correlation as well as the spatial and temporal criteria that we apply before accepting a region as being a receptive field are detailed elsewhere (Warren et al. Koulakov In this chapter, we defined the receptive field to be the contiguous region having a magnitude greater than 4. The size of the receptive field was calculated as the area bounded by this region. The location of the receptive field was defined as the center of mass of the region. Both the size and position were cal- culated at the latency having the peak magnitude. Fitting Receptive Fields To analyze the visuotopic organization of the primary visual cortex, we compared the position of the receptive field with fields estimated by an a‰ne coordinate trans- formation of the locations of the electrode array onto its visual space representation. The particular a‰ne transformation provides 5 degrees of freedom: magnification (SFx and SFy), the rotation (y), and translation (OFFa and OFFe).
