We investigate the biophysical constraints for the emergence of direction selectivity using a model that includes spiking thalamic neurons.
With recent results demonstrating light independent formation of the retinal DS circuitry, our results strongly suggest the formation of the circuitry, i.e., the connections between the second and third order neurons in the visual system, can be genetically programmed, although emergence of direction selectivity in the visual cortex appears to require visual experience.
The result has been a growing appreciation of the fact that 'biological emergence' works in both directions: emergent properties also arise at lower spatial levels than that of the considered system, as demonstrated next by brief examples.
While shifting to a more promising direction, the emergence of MEMS and micromachining back in 1980s holds the potential to complement the existing traditional techniques available.
To document distance and direction of emergence more carefully, additional trials were performed with the camera in the same plane as the soil surface.
The development of a coordinated national strategy adopting an interdisciplinary approach in the design and commissioning of child protection research could help maximise research efforts by reducing duplication and potentially facilitating the emergence of more innovative directions.
In general, the gravitropism angle in the HGMF was smaller than that in the local field when seeds were positioned before emergence in such a way that the direction of the radicle was opposite to that of gravity.
We were looking in the wrong direction for the emergence of a threat to the limited democratic gains of the early Yeltsin years.
But the knee-jerk reaction to perfection and excessive adornment has always been a pendulum swing in the opposite direction, hence the emergence of Bauhaus architecture and the cult of jolie laide in the early 20th century.
Contact in this case would be read as an "all-or-nothing" signal, and the direction of whisker emergence from the FSC would indicate the direction of the object (possibly after a correction for whisker curvature) [12], [21].
