On the mechanisms of inferior olivary signalling : Timing, scaled impact and plasticity mechanisms exerted by the olivary spike
No full textThe inferior olive is regarded to be able to dictate activity in the cerebellum. Its spiking activity comprises the elusive complex spikes. In this dissertation we have looked into different putative roles of the complex spike. We have looked into a differential effect of the single complex spike based on its waveform (chapter one). The second chapter is on rhythmic firing of the complex spikes and whether such rhythmicity induces time conditional spiking to sensory stimulation. In the third chapter we have been looking into plasticity mechanisms influencing simple spike firing in the Purkinje neurons that are under controll of the complex spike activity patterns. In the fourth chapter we have been using calcium imaging to look at activity in multiple climbing fibers simultaneously. We tested whether climbing fibers responsive to different sensory modalities are anatomically organized in the cerebellar cortex

No full textHall–Littlewood functions and the A2 Rogers–Ramanujan identities
No full textWe prove an identity for Hall-Littlewood symmetric functions labelled by the Lie algebra A(2). Through specialization this yields a simple proof of the A(2) Rogers-Ramanujan identities of Andrews, Schilling and the author. (c) 2005 Elsevier Inc. All rights reserved

No full textRogers-Ramanujan Type Identities Involving Double Sums
No full textWe prove four new Rogers-Ramanujan-type identities for double series. They follow from the classical Rogers-Ramanujan identities using the constant term method and properties of Rogers-Szegő polynomials.We are grateful to the referees and the editors for their helpful comments and suggestions. We thank Warnaar for some valuable comments, especially for bringing the work [3] to our attention.

The Determinant of an Elliptic Sylvesteresque Matrix
No full textWe evaluate the determinant of a matrix whose entries are elliptic hypergeometric terms and whose form is reminiscent of Sylvester matrices. A hypergeometric determinant evaluation of a matrix of this type has appeared in the context of approximation theory, in the work of Feng, Krattenthaler, and Xu. Our determinant evaluation is an elliptic extension of their evaluation, which has two additional parameters (in addition to the base q and nome p found in elliptic hypergeometric terms). We also extend the evaluation to a formula transforming an elliptic determinant into a multiple of another elliptic determinant. This transformation has two further parameters. The proofs of the determinant evaluation and the transformation formula require an elliptic determinant lemma due to Warnaar, and the application of two Cn elliptic formulas that extend Frenkel and Turaev's ₁₀V₉ summation formula and ₁₂V₁₁ transformation formula, results due to Warnaar, Rosengren, Rains, and Coskun and Gustafson.We thank Michael Schlosser for helpful discussions. We also thank the referees for many useful suggestions. Research of the first author was supported by a grant of the Austrian Science Fund (FWF), START grant Y463.

Remarks on the paper "Skew Pieri rules for Hall-Littlewood functions" by Konvalinka and Lauve
No full textIn a recent paper Konvalinka and Lauve proved several skew Pieri rules for Hall-Littlewood polynomials. In this note we show that q-analogues of these rules are encoded in a q-binomial theorem for Macdonald polynomials due to Lascoux and the author
Duration of Purkinje cell complex spikes increases with their firing frequency
No full textClimbing fiber (CF) triggered complex spikes (CS) are massive depolarization bursts in the cerebellar Purkinje cell (PC), showing several high frequency spikelet components (±600 Hz). Since its early observations, the CS is known to vary in shape. In this study we describe CS waveforms, extracellularly recorded in awake primates (Macaca mulatta) performing saccades. Every PC analyzed showed a range of CS shapes with profoundly different duration and number of spikelets. The initial part of the CS was rather constant but the later part differed greatly, with a pronounced jitter of the last spikelets causing a large variation in total CS duration. Waveforms did not effect the following pause duration in the simple spike (SS) train, nor were SS firing rates predictive of the waveform shapes or vice versa. The waveforms did not differ between experimental conditions nor was there a preferred sequential order of CS shapes throughout the recordings. Instead, part of their variability, the timing jitter of the CS’s last spikelets, strongly correlated with interval length to the preceding CS: shorter CS intervals resulted in later appearance of the last spikelets in the CS burst, and vice versa. A similar phenomenon was observed in rat PCs recorded in vitro upon repeated extracellular stimulation of CFs at different frequencies in slice experiments. All together these results strongly suggest that the variability in the timing of the last spikelet is due to CS frequency dependent changes in PC excitability
An Bailey tree and Rogers-Ramanujan-type identities
No full textThe Bailey chain of Andrews, Schilling and the author is
extended to a four-parameter Bailey tree. As main application of
this tree, we prove the Kanade-Russell conjecture for a three-parameter family
of Rogers-Ramanujan-type identities related to the principal characters of the
affine Lie algebra . Combined with known -series
results, this further implies an -analogue of the
celebrated Andrews-Gordon -series identities. We also use the
Bailey tree to prove a Rogers-Selberg-type identity for the characters of the
principal subspaces of indexed by arbitrary level-
dominant integral weights . This generalises a result of Feigin,
Feigin, Jimbo, Miwa and Mukhin for .Comment: 41 pages, minor typos correcte
