After 1 week of light exposure, spine turnover and motility decreases (Tropea et al. 2010) which could represent synapse stabilization by LTP.
2pFLIM, which combines two-photon microscopy with fluorescence lifetime measurement, allows one to quantitatively image FRET signal from the tiny volume of spines in light-scattering brain slices (Svoboda and Yasuda, 2006; Yasuda, 2006).
In my skin my also-swallowed beeper, at thirty-seven, went bumping with it, the tiny lights and spines of wires bearing for the seventh time in seven minutes the number for the father's extension underground another sad crack at diversion the father, in his dual mind, would never learn.
These nerves are located in the lower spine, an especially vulnerable area, and the current generation of halorhodopsins require a high intensity of light to get a measurable effect.
Many have dreamed of what the afterlife looks like -- a tunnel of light, a set of pearly white gates -- but Dr. Mary Neal, an orthopedic spine surgeon, says she has seen it first-hand.
Sea urchins' spines direct light to their hard shells, which are photosensitive.
The first light glistens off the frosted spines of the cholla cacti as 30 volunteers in neon yellow shirts fan out to comb the desert under a pale pink sky.
The light on your desk perfectly illuminates the spines of your books (and the photos of your loved ones), but what lurks in the shadows?
Light microscopy was performed on the lumbar and thoracic spines of four WT mice and four TSP-2-null mice, aged 5 months.
As the spines of A. filiformis also constitute the photogenous areas that emit a blue light when the arms are stimulated [ 76, 77], ossicles and pigments could also be involved in light emission.
