This work contains studies to optimize the spatial and temporal resolution of a sodar system in order to measure small scale structures and short time fluctuations of the wind velocity.

The phase reset hypothesis states that the phase of an ongoing neural oscillation, reflecting periodic fluctuations in neural activity between states of high and low excitability, can be shifted by the occurrence of a sensory stimulus so that the phase value become highly constant across trials (Schroeder et al., 2008). From EEG/MEG studies it has...

Initiating an eye movement towards a suddenly appearing visual target is faster when an accessory auditory stimulus occurs in close spatiotemporal vicinity. Such facilitation of saccadic reaction time (SRT) is well-documented, but the exact neural mechanisms underlying the crossmodal effect remain to be elucidated. From EEG/MEG studies it has been...

Procedure for determining lower frequencies. The observed mean SRT with its trend function, a polynomial of degree 6 (left upper panel); the trend (black) of the trend function (red), a polynomial of degree 2 (upper right); the different between both trend functions, zero-mean difference function (lower left); power spectrum of the zero-mean differ...

Although from multisensory research a great deal is known about how the different senses interact, there is little knowledge as to the impact of aging on these multisensory processes. In this study, we measured saccadic reaction time (SRT) of aged and young individuals to the onset of a visual target stimulus with and without an accessory auditory...

The subject of this investigation is the errors appearing in Doppler SODAR measurements due to wind and temperature profiles. Usually the wind velocity is calculated from the measured Doppler shift under the assumption of straight line propagation. Wind and temperature profiles cause a deviation of the rays from the straight path which is given by...
