According to Barlow's seminal "efficient coding hypothesis," the coding strategy of sensory neurons should be matched to the statistics of stimuli that occur in an animal's natural habitat. Using an automatic search technique, we here test this hypothesis and identify stimulus ensembles that sensory neurons are optimized for. Focusing on grasshopper(More)
Sixteen neurons, including vestibular-only (VO), eye-head velocity (EHV), and position-vestibular-pause (PVP) neurons sensitive to head tilt were recorded in the rostromedial and in superior vestibular nuclei. Projection of the otolith polarization vector to the horizontal plane (response vector orientation [RVO]) was determined before and after prolonged(More)
In the yeast Saccharomyces cerevisiae, the Edc3 protein was previously reported to participate in the auto-regulatory feedback loop controlling the level of the RPS28B messenger RNA (mRNA). We show here that Edc3 binds directly and tightly to the globular core of Rps28 ribosomal protein. This binding occurs through a motif that is present exclusively in(More)
To determine whether the COR compensates for the loss of aVOR gain, independent of species, we studied cynomolgus and rhesus monkeys in which all six semicircular canals were plugged. Gains and phases of the aVOR and COR were determined at frequencies ranging from 0.02 to 6 Hz and fit with model-based transfer functions. Following canal plugging in a rhesus(More)
A method is proposed for the multilevel rationing and optimal forecasting of the volumes of electric-energy consumption by an industrial enterprise is offered. On the lower level, the forecasting for individual production sites is performed based on empirical dependences of the specific energy consumption on the quantity of products produced. At a higher(More)
Eukaryotic mRNA decay is a highly regulated process allowing cells to rapidly modulate protein production in response to internal and environmental cues. Mature translatable eukaryotic mRNAs are protected from fast and uncontrolled degradation in the cytoplasm by two cis-acting stability determinants: a methylguanosine (m(7)G) cap and a poly(A) tail at(More)
Three Macaca mulatta were tested in two different tasks. In the naturalistic behavioral experiment, a monkey had to grasp a piece of food from a hollow cube with an asymmetric position of an aperture. The preferable hand was determined. In the second experiment, a monkey performed a more difficult instrumental task: it pulled the lever by the right or by(More)
Studies in 47 right-handed subjects with right and left leading eyes addressed the latent periods of visually-evoked saccades in the horizontal, vertical, and diagonal directions within the field of vision. Visual environments with three levels of temporospatial complexity and two standard time protocols of visual stimulation, with "gap" and "overlap," were(More)
The latencies of visually-guided saccades of 47 right-handed subjects (32 with right leading and 15 with left leading eyes) were studied. Stimulation paradigm was spatially bidimentional, and stimuli were presented along horizontal, vertical and oblique axes. Three levels of visual space complicity and two traditional single-step GAP and OVERLAP temporal(More)
Saccadic latencies of visually-guided saccades of 10 right-handed subjects with right-leading eyes were studied. Stimulation paradigm was spatially bidimentional, and stimuli were shown along horizontal and vertical meridians. Three traditional single step GAP - NO DELAY - OVERLAP temporal paradigms were used. In the first experiment, each paradigm was(More)
