This has led to the hypothesis that parallel activation of cardiorespiratory and locomotor systems from the midbrain could form part of the \u2018central command\u2019 mechanism of exercise. However, the degree to which subcortical structures play a role in cardiovascular activation in awake humans has not been established. We studied the effects on heart rate (HR) and mean arterial blood pressure (MAP) of electrically stimulating the thalamus and basal ganglia in awake humans undergoing neurosurgery for movement disorders (<jats:italic>n<\/jats:italic>= 13 Parkinson's disease, <jats:italic>n<\/jats:italic>= 1 myoclonic dystonia, <jats:italic>n<\/jats:italic>= 1 spasmodic torticollis). HR and MAP increased during high frequency (&gt; 90 Hz) electrical stimulation of the thalamus (HR 5 \u00b1 3 beats min<jats:sup>\u22121<\/jats:sup>, <jats:italic>P =<\/jats:italic> 0.002, MAP 4 \u00b1 3 mmHg, <jats:italic>P =<\/jats:italic> 0.05, <jats:styled-content><jats:italic>n<\/jats:italic>= 9<\/jats:styled-content>), subthalamic nucleus (HR 5 \u00b1 3 beats min<jats:sup>\u22121<\/jats:sup>, <jats:italic>P =<\/jats:italic> 0.002, MAP 5 \u00b1 3 mmHg, <jats:italic>P =<\/jats:italic> 0.006, <jats:italic>n<\/jats:italic>= 8) or substantia nigra (HR 6 \u00b1 3 beats min<jats:sup>\u22121<\/jats:sup>, <jats:italic>P =<\/jats:italic> 0.001, MAP 5 \u00b1 2 mmHg, <jats:italic>P =<\/jats:italic> 0.005, <jats:italic>n<\/jats:italic>= 8). This was accompanied by the facilitation of movement, but without the movement itself. Stimulation of the internal globus pallidus did not increase cardiovascular variables but did facilitate movement. Low frequency (&lt; 20 Hz) stimulation of any site did not affect cardiovascular variables or movement. Electrical stimulation of the midbrain in awake humans can cause a modest increase in cardiovascular variables that is not dependent on movement feedback from exercising muscles. The relationship between this type of response and that occurring during actual exercise is unclear, but it indicates that subcortical command could be involved in \u2018parallel activation\u2019 of the locomotor and cardiovascular systems and thus contribute to the neurocircuitry of \u2018central command\u2019.<\/jats:p>","DOI":"10.1113\/jphysiol.2001.014621","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T12:45:57Z","timestamp":1027773957000},"page":"615-621","source":"Crossref","is-referenced-by-count":101,"title":["Electrical stimulation of the midbrain increases heart rate and arterial blood pressure in awake humans"],"prefix":"10.1113","volume":"539","author":[{"given":"Judith M.","family":"Thornton","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tipu","family":"Aziz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Schlugman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David J.","family":"Paterson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2002,3]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1995.83.2.0271"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0031-9384(78)90212-3"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00001756-199112000-00014"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/0031-9384(94)90275-5"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/0031-9384(95)02082-9"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1152\/jappl.1992.72.1.121"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s004240050397"},{"key":"e_1_2_5_9_1","first-page":"205","article-title":"Identification of cardiovascular cell groups in the brain stem","volume":"6","author":"Dampney R.
