Understanding the mechanisms of episodic memory requires linking behavioral data and lesion effects to data on the dynamics of cellular membrane potentials and population interactions within brain regions. Linking behavior to specific membrane channels and neurochemicals has implications for therapeutic applications. Lesions of the hippocampus, entorhinal cortex and subcortical nuclei impair ep...

Evidence supporting performance enhancing effects of kinesiotape in sports is missing. The aims of this study were to evaluate effects of kinesiotape applications with regard to shooting and throwing performance in 26 amateur soccer and 32 handball players, and to further investigate if these effects were influenced by the players' level of performance. Ball speed as the primary outcome and acc...

Cortical neurons have been reported to use both rate and temporal codes. Here we describe a novel mode in which each neuron generates exactly 0 or 1 action potentials, but not more, in response to a stimulus. We used cell-attached recording, which ensured single-unit isolation, to record responses in rat auditory cortex to brief tone pips. Surprisingly, the majority of neurons exhibited binary ...

The ventral spinal roots contain the axons of spinal motoneurons and provide the only location in the peripheral nervous system where recorded neural activity can be assured to be motor rather than sensory. This study demonstrates recordings of single unit activity from these ventral root axons using floating microelectrode arrays (FMAs). Ventral root recordings were characterized by examining ...

In the present study, the effect of NBM lesion on the temporal characteristics of response integration evoked by multiple whisker stimulations in the barrel cortex of rats was studied. Nucleus basalis of Meynert (NBM) projects to widespread areas of the cortex and provides the major cholinergic input (80%) to the cerebral cortex. In this study we examined the effects of NBM lesion on the respon...

PURPOSE To measure the dependence of the size of the pupils of mice on steady retinal illumination. METHODS Anesthetized C57BL/6 mice aged 7 to 8 weeks were placed in a ganzfeld chamber in darkness, and in monochromatic (510 nm) and white light whose intensity was varied more than 6 log units. The pupils of the mice were photographed with an infrared video camera and recorded on videotape and...

Within a general framework for seamless acoustic man-machine interfaces, common problems for different classes of applications are identified. Removing loudspeaker echoes, noise, and reverberation of local sources from microphone signals, and conditioning loudspeaker signals to eliminate reverberation and noise at a listener’s ears constitute problems of system identification and signal separat...
