“…The conjunct of all those axons compose the olfactory nerve (Graziadei 1971). There is evidence of ephaptic interaction among the axons of the same filet (Lewalle et al 1995, Blinder et al 2003, which is also supported by a computational model of this structure (Bokil et al 2001).…”

The majority of the biophysical models of olfaction have been focused on the electrical properties of the system, which is justified by the relative facility of recording the electrical activity of the olfactory cells. However, depending on the level of detail utilized, a biophysical model can explore molecular, cellular and network phenomena. This review presents the state of the art of the biophysical approach to understanding olfaction. The reader is introduced to the principal problems involving the study of olfaction and guided gradually to comprehend why it is important to develop biophysical models to investigate olfaction. A large number of representative biophysical efforts in olfaction, their main contributions, the trends for the next generations of biophysical models and the improvements that may be explored by future biophysicists of olfaction have been reviewed.

“…Many of these latter studies have utilized wavelets for spike sorting (Zouridakis and Tam 1997) or denoising (Koshiya and Smith 1999) applications, rather than for analyzing neuronal spiking in the time-frequency domain (Przybyszewski 1991;Lewalle et al 1995). Here, wavelet analysis successfully revealed multisecond periodicities in GP spiking activity, and complemented our standard spectral analysis technique, the Lomb periodogram.…”

Previous studies have shown that direct-acting dopamine agonists modulate the multisecond oscillations which are present in globus pallidus spike trains in vivo inPeriodicities in brain electrical activity occur in many nuclei and in many frequency ranges, and have been described in the electroencephalogram, in field potentials, and in the spiking activity of single neurons. Much of the attention that brain periodicities have received has been directed to the range of frequencies from 1 Hz (the slow end of the delta rhythm) up to roughly 60 Hz (the fast end of the gamma rhythm). However, recent studies have demonstrated that much slower periodic oscillations are commonly present in the spike trains of tonically firing neurons in the basal ganglia. The firing rates of a majority of neurons in the globus pallidus (GP), the subthalamic nucleus, the substantia nigra pars reticulata and the entopeduncular nucleus oscillate in vivo with slow periods, most often in the range of 10-60 s (0.1-0.017 Hz) (Ruskin et al. 1999a;Ruskin et al. 1999c;Wichmann et al. 1999;Allers et al. 2000). These multisecond periodicities in tonic activity are present in awake rats, but are markedly attenuated by general anesthesia (Ruskin et al. 1999a).One of the most striking characteristics of these slow oscillations is their strong modulation by dopamine

[1] This paper presents a new analysis of four time series of paleoclimate data, using wavelet methods to determine the timings and characteristics of the ice-age terminations. We use an antisymmetric wavelet which detects locations in the time series where there are large changes. The results are consistent with previous work, but we have, for the first time, been able to explore the features of the individual terminations in an objective way. We find that at the terminations the interval between atmospheric carbon dioxide changes and sea level is about 7 kyr, compared with 15 kyr obtained using Fourier methods, which average the phase over the whole 100 kyr signal. The sea level change is the fastest but occurs after the other three components.INDEX TERMS: 3344 Meteorology and Atmospheric Dynamics: Paleoclimatology; 4267 Oceanography: General: Paleoceanography; 9604 Information Related to Geologic Time: Cenozoic; 9820 General or Miscellaneous: Techniques applicable in three or more fields; KEYWORDS: wavelet analysis, ice-age termination, paleoclimate core data Citation: Hargreaves, J.
