Abstract
Background: Deep brain stimulation of the subthalamic nucleus alleviates motor symptoms in Parkinson's disease patients. However, some patients suffer from cognitive and emotional changes. These side effects are most likely caused by current spread to the cognitive and limbic territories in the subthalamic nucleus. The aim of this study was to identify the motor part of the subthalamic nucleus to reduce stimulation-induced behavioral side effects, by using motor cortex stimulation. Methods: We describe the results of subthalamic nucleus neuronal responses to stimulation of the hand area of the motor cortex and evaluate the safety of this novel technique. Results: Responses differed between regions within the subthalamic nucleus. In the anterior and lateral electrode at dorsal levels of the subthalamic nucleus, an early excitation (˜5-4.5 ms) and subsequent inhibition (45-105 ms) were seen. The lateral electrode also showed a late excitation (˜125-160 ms). Focal seizures were observed following motor cortex stimulation. Conclusions: To prevent seizures the current density should be lowered, so that motor cortex stimulation-evoked responses can be safely used during deep brain stimulation surgery.

In the anterior and lateral electrode at dorsal levels of the subthalamic nucleus, an early excitation (˜5-4.5 ms) and subsequent inhibition (45-105 ms) were seen. The lateral electrode also showed a late excitation (˜125-160 ms). Focal seizures were observed following motor cortex stimulation. Conclusions: To prevent seizures the current density should be lowered, so that motor cortex stimulation-evoked responses can be safely used during deep brain stimulation surgery.</s0></fC01><fC02 i1="01" i2="X"><s0>002B17</s0></fC02><fC02 i1="02" i2="X"><s0>002B26I</s0></fC02><fC03 i1="01" i2="X" l="FRE"><s0>Maladie de Parkinson</s0><s2>NM</s2><s5>01</s5></fC03><fC03 i1="01" i2="X" l="ENG"><s0>Parkinson disease</s0><s2>NM</s2><s5>01</s5></fC03><fC03 i1="01" i2="X" l="SPA"><s0>Parkinson enfermedad</s0><s2>NM</s2><s5>01</s5></fC03><fC03 i1="02" i2="X" l="FRE"><s0>Pathologie du système nerveux</s0><s5>02</s5></fC03><fC03 i1="02" i2="X" l="ENG"><s0>Nervous system diseases</s0><s5>02</s5></fC03><fC03 i1="02" i2="X" l="SPA"><s0>Sistema nervioso patología</s0><s5>02</s5></fC03><fC03 i1="03" i2="X" l="FRE"><s0>Neurophysiologie</s0><s5>09</s5></fC03><fC03 i1="03" i2="X" l="ENG"><s0>Neurophysiology</s0><s5>09</s5></fC03><fC03 i1="03" i2="X" l="SPA"><s0>Neurofisiología</s0><s5>09</s5></fC03><fC03 i1="04" i2="X" l="FRE"><s0>Noyau sousthalamique</s0><s5>10</s5></fC03><fC03 i1="04" i2="X" l="ENG"><s0>Subthalamic nucleus</s0><s5>10</s5></fC03><fC03 i1="04" i2="X" l="SPA"><s0>Núcleo subtalámico</s0><s5>10</s5></fC03><fC03 i1="05" i2="X" l="FRE"><s0>Stimulation cérébrale profonde</s0><s4>CD</s4><s5>96</s5></fC03><fC03 i1="05" i2="X" l="ENG"><s0>Deep brain stimulation</s0><s4>CD</s4><s5>96</s5></fC03><fC07 i1="01" i2="X" l="FRE"><s0>Pathologie de l'encéphale</s0><s5>37</s5></fC07><fC07 i1="01" i2="X" l="ENG"><s0>Cerebral disorder</s0><s5>37</s5></fC07><fC07 i1="01" i2="X" l="SPA"><s0>Encéfalo patología</s0><s5>37</s5></fC07><fC07 i1="02" i2="X" l="FRE"><s0>Syndrome extrapyramidal</s0><s5>38</s5></fC07><fC07 i1="02" i2="X" l="ENG"><s0>Extrapyramidal syndrome</s0><s5>38</s5></fC07><fC07 i1="02" i2="X" l="SPA"><s0>Extrapiramidal síndrome</s0><s5>38</s5></fC07><fC07 i1="03" i2="X" l="FRE"><s0>Maladie dégénérative</s0><s5>39</s5></fC07><fC07 i1="03" i2="X" l="ENG"><s0>Degenerative disease</s0><s5>39</s5></fC07><fC07 i1="03" i2="X" l="SPA"><s0>Enfermedad degenerativa</s0><s5>39</s5></fC07><fC07 i1="04" i2="X" l="FRE"><s0>Pathologie du système nerveux central</s0><s5>40</s5></fC07><fC07 i1="04" i2="X" l="ENG"><s0>Central nervous system disease</s0><s5>40</s5></fC07><fC07 i1="04" i2="X" l="SPA"><s0>Sistema nervosio central patología</s0><s5>40</s5></fC07><fC07 i1="05" i2="X" l="FRE"><s0>Encéphale</s0><s5>42</s5></fC07><fC07 i1="05" i2="X" l="ENG"><s0>Encephalon</s0><s5>42</s5></fC07><fC07 i1="05" i2="X" l="SPA"><s0>Encéfalo</s0><s5>42</s5></fC07><fC07 i1="06" i2="X" l="FRE"><s0>Système nerveux central</s0><s5>43</s5></fC07><fC07 i1="06" i2="X" l="ENG"><s0>Central nervous system</s0><s5>43</s5></fC07><fC07 i1="06" i2="X" l="SPA"><s0>Sistema nervioso central</s0><s5>43</s5></fC07><fN21><s1>156</s1></fN21><fN44 i1="01"><s1>OTO</s1></fN44><fN82><s1>OTO</s1></fN82></pA></standard><server><NO>PASCAL 12-0198674 INIST</NO><ET>Subthalamic Neuronal Responses to Cortical Stimulation</ET><AU>JANSSEN (Marcus L.

However, some patients suffer from cognitive and emotional changes. These side effects are most likely caused by current spread to the cognitive and limbic territories in the subthalamic nucleus. The aim of this study was to identify the motor part of the subthalamic nucleus to reduce stimulation-induced behavioral side effects, by using motor cortex stimulation. Methods: We describe the results of subthalamic nucleus neuronal responses to stimulation of the hand area of the motor cortex and evaluate the safety of this novel technique. Results: Responses differed between regions within the subthalamic nucleus. In the anterior and lateral electrode at dorsal levels of the subthalamic nucleus, an early excitation (˜5-4.5 ms) and subsequent inhibition (45-105 ms) were seen. The lateral electrode also showed a late excitation (˜125-160 ms). Focal seizures were observed following motor cortex stimulation. Conclusions: To prevent seizures the current density should be lowered, so that motor cortex stimulation-evoked responses can be safely used during deep brain stimulation surgery.</EA><CC>002B17; 002B26I</CC><FD>Maladie de Parkinson; Pathologie du système nerveux; Neurophysiologie; Noyau sousthalamique; Stimulation cérébrale profonde</FD><FG>Pathologie de l'encéphale; Syndrome extrapyramidal; Maladie dégénérative; Pathologie du système nerveux central; Encéphale; Système nerveux central</FG><ED>Parkinson disease; Nervous system diseases; Neurophysiology; Subthalamic nucleus; Deep brain stimulation</ED><EG>Cerebral disorder; Extrapyramidal syndrome; Degenerative disease; Central nervous system disease; Encephalon; Central nervous system</EG><SD>Parkinson enfermedad; Sistema nervioso patología; Neurofisiología; Núcleo subtalámico</SD><LO>INIST-20953.354000506923350190</LO><ID>12-0198674</ID></server></inist></record>Pour manipuler ce document sous Unix (Dilib)
