The design of an air sonar device with a new form binaural display is described which aids the blind in perceiving their environment. Some limitations knowledge human perception and influence this has on specification for are discussed. Inherent aid both terms technology development performance also explained. paper what expected man-machine control system mobility setting discusses technique evaluating manmachinesystem so as to assess machine performance.
Fast oscillations in neural assemblies have been proposed as a mechanism to facilitate stimulus representation variety of sensory systems across animal species. In the olfactory system, intervention studies suggest that gamma frequency range play role fine odor discrimination. However, there is still no direct evidence such are intrinsically altered intact aid disambiguation. Here we show oscillatory power rat bulb during two-alternative choice task modulated system according demands with...
Synchronized neural activity is believed to be essential for many CNS functions, including neuronal development, sensory perception, and memory formation. In several brain areas GABA A receptor–mediated synaptic inhibition thought important the generation of synchronous network activity. We have used receptor β3 subunit deficient mice (β3−/−) study role GABAergic in oscillations olfactory bulb (OB) reveal such olfaction. The expression functional receptors was drastically reduced (>93%)...
Field potentials were recorded simultaneously from the olfactory bulb (OB), prepyriform cortex (PPC), entorhinal (EC), and dentate gyrus (DG) of rats trained to respond appetitively reinforced odors. Preafferent anticipatory events in beta band (12-35 Hz) suggest transmission EC OB before odorant stimulus. Gamma (35-120 power regions is significantly reduced during stimulus presentation as compared with high values preafferent expectation. High coherence PPC gamma activity preodorant control...
Several studies have shown that memory consolidation relies partly on interactions between sensory and limbic areas. The functional loop formed by the olfactory system hippocampus represents an experimentally tractable model can provide insight into this question. It had been previously odor-learning associated beta band oscillations (15-30 Hz) of local field potential in rat are enhanced with criterion performance, but it was unknown if these involve networks beyond system. We recorded...
Performance and cognitive effort in humans have recently been related to amplitude multisite coherence of alpha (7-12 Hz) theta (4-7 band electroencephalogram oscillations. I examined this phenomenon rats by using oscillations the local field potential signify sniffing as a sensorimotor process. Olfactory bulb (OB) are coherent with those dorsal hippocampus (HPC) during odor two-odor olfactory discrimination task. Coherence is restricted high-frequency (6-12 associated directed OB type 1...
Sensory-motor relationships are part of the normal operation sensory systems. Sensing occurs in context active sensor movement, which turn influences processing. We address such a process rat olfactory system. Through recordings diaphragm electromyogram (EMG), we monitored motor output respiratory circuit involved sniffing behavior, simultaneously with local field potential (LFP) bulb (OB) rats moving freely familiar environment, where they display wide range frequencies. show that OB LFP...
Olfactory system beta (15-35 Hz) and gamma (40-110 oscillations of the local field potential in mammals have both been linked to odor learning discrimination. Gamma represent activity a network within olfactory bulb, engagement systemwide network. Here, we test whether different cognitive modes using demands go/no-go two-alternative choice tasks that previously were suggested favor or oscillations, respectively. We reconcile previous studies show occur tasks, with dominating early sampling...
Gamma oscillations (40-100 Hz), originally seen in the olfactory bulb (OB), have long been a defining characteristic of sensory coding system. This study proposes that gamma are two types, associated with different behavioral features and synaptic origins within OB. Local field potentials were recorded from rat mouse OBs during various periods (immobility, alert motionlessness, exploration odor discrimination). High frequency activity (65-100 Hz) is shown to be correlated sniff cycle,...
We previously showed that in a two-alternative choice (2AC) task, olfactory bulb (OB) gamma oscillations (approximately 70 Hz rats) were enhanced during discrimination of structurally similar odorants (fine discrimination) versus dissimilar (coarse discrimination). In other studies (mostly employing go/no-go tasks) multiple labs, beta (15-35 Hz) dominate the local field potential (LFP) signal areas odor sampling. Here we analyzed frequency band power and pairwise coherence 2AC task. show...
Odor mixtures are perceived as different from (configural) or the same (elemental) their components. Recent studies (L. M. Kay, C. A. Lowry, & H. Jacobs, 2003; Wiltrout, S. Dogra, Linster, 2003) propose that component structural perceptual similarities predict configural properties of binary mixtures. The authors evaluated this in rats using 4 with varying similarity (eucalyptol-benzaldehyde, eugenol-benzaldehyde, octanol-octanal, and [+/-]-limonene). range tested ratios for each mixture was...
Gamma oscillations in the olfactory bulb can be produced as an interaction of subthreshold (STOs) mitral cells (MCs) with inhibitory granule (GCs). The mechanism does not require that GCs spike, and we work a regime which MCs fire at rates lower than fast gamma rhythm they create. frequency network is STOs, allowing to modulated amplitude only small changes frequency. could also obtained spiking GCs, but for firing close population rate. Our differs from more standard description...
