Neuronal　membrane　capacitance　C　(m)　is　one　of　the　prominent　factors　in　action　potential　initiation　and　propagation　and　then　influences　the　firing　patterns　of　neurons.　Exploring　the　roles　that　C　(m)　plays　in　different　firing　patterns　can　facilitate　the　understanding　of　how　different　factors　might　influence　neuronal　firing　behaviors.　However,　the　impacts　of　variations　in　C　(m)　on　neuronal　firing　patterns　have　been　only　partly　explored　until　now.　In　this　study,　the　influence　of　C　(m)　on　burst　firing　behaviors　of　a　two-compartment　pyramidal　neuron　(including　somatic　compartment　and　dendritic　compartment)　was　investigated　by　means　of　computer　simulation,　the　value　of　C　(m)　in　each　compartment　was　denoted　as　C　(m,s)　and　C　(m,d),　respectively.　Two　cases　were　considered,　in　the　first　case,　we　let　C　(m,s)　=　C　(m,d),　and　then　changed　them　simultaneously.　While　in　the　second　case,　we　assumed　C　(m,s)　not　equal　C　(m,d),　and　then　changed　them,　respectively.　From　the　simulation　results　obtained　from　these　two　cases,　it　was　found　that　the　variation　of　C　(m)　in　the　somatic　compartment　and　the　dendritic　compartment　show　much　difference,　simulated　results　obtained　from　the　variation　of　C　(m,d)　have　much　more　similarities　than　that　of　C　(m,s)　when　comparing　with　the　results　obtained　in　the　first　case　under　which　C　(m,s)　=　C　(m,d).　These　different　effects　of　C　(m,s)　and　C　(m,d)　on　neuronal　firing　behaviors　may　result　from　the　different　topology　and　functional　roles　of　soma　and　dendrites.　Numerical　results　demonstrated　in　this　paper　may　give　us　some　inspiration　in　understanding　the　possible　roles　of　C　(m)　in　burst　firing　patterns,　especially　their　transitions　in　compartmental　neurons.
