A minimal and convenient experimental set-up is described, which allows an easy characterization of crystal tuning forks, especially after the modifications introduced to exploit them as sensors in nanomechanics and in force microscopy techniques. Th

Fundamental sources of noise in sensory transduction

The contribution of chemical steps in trasduction chains to the output noise of a receptor cell (as opposed to the noise inherent in the stimulus,e.g., a dim light flash) has been evaluated both analytically and by a computer simulation study on a si

Scanning ion conductance microscopy (SICM) is a scanning probe microscopy particularly suitable for the investigation of living biological specimens due to its low invasivity. Recently, this technique has been used not only to perform 3D-imaging, but

Photobehavior of Halobacterium halobium

Autor: S. Lucia, D. Petracchi, Cesare Ascoli

Publikováno v: Biophysical Journal. 61:1529-1539

Sequences of reversals recorded by single-cell observation of Halobacterium halobium are analyzed. Autocorrelation functions of spontaneous and stimulated reversals are computed; the results show that the only periodicity present in our data is that

Behavioral responses of Halobacterium salinarum appear as changes in the frequency of motion reversals. Turning on orange light decreases the reversal frequency, whereas blue light induces reversals. Light pulses normally induce the same response as
