Multi Units Analysis Clausole campione

Multi Units Analysis. In the CHR condition we found 162 out of 256 (63%) multi-units (89/128 - 70% - in Mk1 and 73/128 - 57% - in Mk2) with a significant modulation of their discharge during at least one behaviour, whereas the remaining fraction did not appear to be responsive for any of the scored behaviours (Figure 24A). In the NER condition the number of neurons modulated for at least one behaviour was 166 out of 256 (65%) - 87/128 (68%) in Mk1 and 79/128 (62%) in Mk2 (Figure 24B). into the mouth. In Figure 26 we graphically reported the number of multi-units showing an increase in their firing rate for each behaviour tested in the two conditions. Differently from single unit results, not all the grasping behaviours modulated more units in the CHR condition than in the NER condition: a distinction based on the target of the grasping action seems to be necessary in order to explain these data. In particular, grasping pieces of fruits modulated a much higher number of neurons in the CHR condition rather than in the NER condition, independently from the hand used. This is not true for grasping actions directed toward neutral objects, which showed a comparable number of tuned multi-units in the two conditions when performed with the controlateral hand and a much higher number of units modulated in the NER than in the CHR condition when performed with the ipsilateral hand. A high number of units, especially for Mk1, was also modulated by mouth behaviours - either passive or active - in the CHR conditions whereas in the NER this number generally dropped down, in particular for bringing food to the mouth behaviours performed with the ipsilateral hand. Passively receiving fruit juice through a syringe is an exception to this rule because this behaviour modulates more units in the NER condition than in the CHR condition.
