....output in sensory processing. Previous in vitro and in vivo experiments have focused both upon specifying the mechanism for burst discharge of ELL pyramidal cells, and showing methods for the modulation of burst output (Turner et al. 1994, 1996; Turner and Maler,1999; Lemon and Turner, 2000; Bastian and Nguyenkim, 2001; Rashid et al. 2001) Lemon and Turner (2000) have shown that a frequency dependent or conditional action potential backpropagation along the proximal apical dendrite underlies both the evolution and termination of ELL burst output. Recently, through the construction and analysis of a detailed ....

....indicates that changing the magnitude of input to the cell may cause a transition from periodic spiking to chaotic bursting. In ELL pyramidal cells a transition from tonic firing to highly variable bursting has been observed as applied depolarizing current is increased (Lemon and Turner, 2000; Bastian and Nguyenkim, 2001; Doiron and Turner, unpublished results) It remains to be shown that the experimentally observed bursting is indeed chaotic; preliminary results suggest that such an analysis is difficult due to non stationarity in the data (Doiron and Turner, unpublished observations) Nonetheless, ....
