Motivated by hot sun on cars, Jo decided to create a photo series dedicated to the spike of light that's caused when the sun hits a shiny surface.
He described his mother as a "madonna swathed in velvet, smothered in diamonds, bedecked with nocturnal plumes, a glittering chestnut tree, spiked with rays of light, tall, abstracted, torn between the last promptings to be good and one last look in the mirror".
Your goal in taking pictures with a digital camera most of the time will be to make sure that your spikes of dark and light aren't going beyond the left or the right side of the screen.
Neurons were identified as PVs or SOMs if they responded to brief (5 ms) flashes of light with spikes within 1.5 4.5 ms of laser pulse onset.
Spike fidelity represents the percentage of light pulses in the given 5 s bin of inhibition that evoke at least one spike during the 30 ms pulse.
Light-evoked spikes were collected from time windows during a light stimulation interval; odor-evoked spikes were collected during the odor stimulation interval; background spikes were collected from intervals devoid of light and odor stimulations.
Whenever the price of light crudes spiked, we'd see a lot of different heavies come on the market".
(A ) An example Golgi cell current-clamp recording showing spike-timing response to train of light pulses (upper panel, 6 traces).
A 500 ms step of light modulated spiking in 37 of 47 cells (79%), confirming that the population of bipolar cells made wide-spread use of spikes to encode a visual stimulus.
Quantification of light evoked spiking probability (E ), latency (F ) and standard deviation of the latency (jitter) (G ) for a range of photostimulation durations recorded from both Gad2 -Chred(red; n = 5 cells) and Thy1 -ChR2 (green; n = 7 cells) mice.
Interest in Congressman Parker Griffith has spiked today in light of the news that he plans to change his party affiliation from Democrat to Republican.
