4.4.2.1 Enabling Evoked Single Sweep Stimulation
The check boxes in the ‘Single Train or Pulse Sweep’ panel in Fig. 4.4.2.1 (top of top panel) determine
whether these single sweeps can be evoked by clicking single Run Buttons, Function Keys or Run Menu
items (Sections 3.1.5 and 3.3, and Figs. 3.1.5.1 and 3.2.6). Fig. 4.4.2.1 shows a Single T0sweep is
enabled and only the ‘Single T0’ button of all the Single Sweep Run Buttons in the bottom panel is
enabled and ready to be clicked on.
4.4.2.2 Fast Repetitive Pulse Sweep (LTD) Stimulation
The check boxes in the ‘Fast Repeat Pulse Sweeps (LTD)’ panel in Fig. 4.4.2.1 (middle of the top panel)
determine whether these repeat pulse sweeps (P0 and P1) can be evoked by clicking single Run Buttons,
Function Keys or Run Menu items (Sections 3.1.5 and 3.3, and Figs. 3.1.5.1 and 3.2.6). Fig. 4.4.2.1
shows Repeat P0 Sweeps is enabled and only the ‘Repeat P0’ button of all the Repeat Sweeps Run
Buttons in the bottom panel is enabled and ready to be clicked on.
The first field to the right of the check box determines the number of times a sweep is repeated. The next
field to the right is the period of the sweep (in seconds). The text following the equal sign is the total time
of the sweep in min:sec.
Next, the ‘Avg’ check box determines whether the Pulse Sweeps are to be signal averaged. If the ‘Avg’
check box is checked, then another field on the right, the ‘NumSweeps to Avg’ field comes into view.
Finally, on the right, if the ‘Add Delay’ check box is checked, an additional delay period (equal to the
preceding normal slow repeat sweep period) between the end of the LTD stimulation and the resumption
of the normal slow repeat sweep stimulation (Fig.4.4.2.2.1). Otherwise there will be no added delay, and
it is possible that the first normal sweep will occur immediately after the LTD stimulation without any
obvious gap.
