It is a columnar cactus that grows up to 5 metres, with stems branching from the base. The cells of the embryonic disc were columnar epithelial cells. Columnar joints appear to be well formed in lava beds cooled rapidly from below. Patterns and shapes amorphous arabesque argyle asymmetrically asymmetry flecked formless formlessly fretted geoglyph scalloped scissor semilunaris shapeable shaped wavery wavily weave willow pattern zigzag Examples of columnarcolumnar Furthermore, he omits columnar structure entirely from this discussion.

In no case did we observe a columnar pattern in the cor tical response to one pair of gratings but not the other. In the actual tactile sensor, the columnar feeler is supported by a hole of a stainless steel sheet. We have shown here the relationships between fully nonlinear standing periodic wavetrains and solitary waves and the underlying columnar flows. One hypothesis for the widespread presence of columnar organization depends on computational necessity-information for neuronal computation must be present within the span of local circuits.

Note that columnar structure in the selective responses for cardinal and oblique orientations appear to emerge simultaneously. A three-dimensional sketch of the trajectories of each portion of the columnar vortex pair is displayed in figure 14. The columnar vortex pair is literally chopped into small individual pancake dipoles. These solitary-wave flow fields approach the primary columnar flow asymptotically a t large upstream and downstream distances. Progress to this columnar stage is relatively slow with a timescale much greater than a millisecond and the gravity-induced straining is clearly important. Oscillatory responses in cat visual cor tex exhibit inter-columnar synchronization which reflects global stimulus proper ties. The lava flows are occasionally columnar jointed and commonly show spheroidal weathering, but appear to lack pillow lava structures. The sensor's single cell consists of a columnar feeler and 2-by-2 conical feelers. These examples are from corpora and from sources on the web.
