Squeezing dendritic necks
Squeezing dendritic necks Sure enough, diffusion restriction was induced in individual dendrites by pairing two excitatory signals from pre-synaptic and postsynaptic sources. The clampdown at the dendrite neck may involve cross-linking of an actin mesh, or blockage by mitochondria or smooth endoplasmic reticulum. Either way, says Sabatini, “if a spine can hold onto [molecules such as] active ki...
متن کاملHow Bird Necks Get Naked
Some birds such as vultures, ostriches, and certain species of stork have naked necks. This unusual feature allows them to tolerate heat better in hot climates. And, for vultures, the absence of neck feathers helps them poke about the insides of carrion unimpeded. The fossil record provides no evidence that naked necks evolved in a common ancestor, leaving scientists to explore other avenues to...
متن کاملWhy sauropods had long necks; and why giraffes have short necks
The necks of the sauropod dinosaurs reached 15 m in length: six times longer than that of the world record giraffe and five times longer than those of all other terrestrial animals. Several anatomical features enabled this extreme elongation, including: absolutely large body size and quadrupedal stance providing a stable platform for a long neck; a small, light head that did not orally process ...
متن کاملMemorandum of Transmittal
We survey recent work on designing and evaluating quantum computing implementations based on nuclear or bound-electron spins in semiconductor heterostructures at low temperatures and in high magnetic fields. General overview is followed by a summary of results of our theoretical calculations of decoherence time scales and spin–spin interactions. The latter were carried out for systems for which...
