While the mechanisms responsible remain unknown, activation of the sympathetic nervous system may be implicated. Using isotope dilution methodology, investigations of whole\u2010body and regional sympathetic nervous activity have failed to show any differences between patients with panic disorder and healthy subjects. Using direct recording of single unit efferent sympathetic vasoconstrictor nerve activity by microneurography we examined sympathetic nervous function in patients with panic disorder more precisely than previously reported. The activity of multiunit and single unit vasoconstrictor sympathetic nerves was recorded at rest at the level of the peroneal nerve in 10 patients diagnosed with panic disorder and in nine matched healthy volunteers. Multiunit sympathetic activity was not different between the two groups (26 \u00b1 3 bursts min\n                    <jats:sup>\u22121<\/jats:sup>\n                    in patients with panic disorder and 28 \u00b1 3 bursts min\n                    <jats:sup>\u22121<\/jats:sup>\n                    in controls). The firing frequency of single unit vasoconstrictor neurones was also similar between the two groups (0.38 \u00b1 0.09\n                    <jats:italic>versus<\/jats:italic>\n                    0.22 \u00b1 0.03 Hz). However, the probability of firing during a sympathetic burst was higher in patients with panic disorder compared with healthy controls (45 \u00b1 5%\n                    <jats:italic>versus<\/jats:italic>\n                    32 \u00b1 3%,\n                    <jats:italic>P<\/jats:italic>\n                    &lt; 0.05). When only the neural bursts during which the vasoconstrictor neurone was active were considered, we found that in patients with panic disorder the neurones tended to fire more often in a \u2018multiple spike\u2019 pattern than in the controls (i.e. the probability of the neurone firing twice was 25 \u00b1 3% in patients with panic disorder compared with 14 \u00b1 3% in controls). Quantification from single vasoconstrictor unit recording provides evidence of a disturbed sympathetic firing pattern in patients with panic disorder.\n                  <\/jats:p>","DOI":"10.1113\/jphysiol.2005.100040","type":"journal-article","created":{"date-parts":[[2005,11,24]],"date-time":"2005-11-24T20:24:10Z","timestamp":1132863850000},"page":"637-643","source":"Crossref","is-referenced-by-count":51,"title":["Single\u2010unit analysis of sympathetic nervous discharges in patients with panic disorder"],"prefix":"10.1113","volume":"570","author":[{"given":"Elisabeth","family":"Lambert","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elodie","family":"Hotchkin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marlies","family":"Alvarenga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ciaran","family":"Pier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey","family":"Richards","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Barton","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tye","family":"Dawood","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Murray","family":"Esler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gavin","family":"Lambert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2006,1,16]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0006-3223(00)01078-7"},{"key":"e_1_2_5_3_1","volume-title":"Diagnostic and Statistical Manual of Mental Disorders","author":"American Psychiatric Association","year":"1994"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.4088\/JCP.v58n0103"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1001\/archpsyc.1982.04290060051010"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-1781(03)00045-3"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1152\/japplphysiol.00899.2001"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1196\/annals.1296.062"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.91.2.351"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1176\/ajp.141.7.857"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.100.12.1305"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.89.5.1992"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.90.5.2225"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-1716.1992.tb09415.x"},{"key":"e_1_2_5_15_1","doi-asserted-by":"crossref","first-page":"863","DOI":"10.1016\/S0895-7061(04)00844-1","article-title":"Reduced sympathoneural responses to the cold pressor test in individuals with essential hypertension and in those genetically predisposed to hypertension.
