| Method |
Researchers mimicked the receptor potential
triggering nematocyst discharge
[ref 6 in article] by applying a short-step
depolarization and analyzed
discharge in >1200 instances
with an electronic framing- streak
camera (for details see Figure S1 in
Supplemental Data). They resolved
the ultra-fast phase of discharge
by capturing an intermediate
stage between the resting capsule
and the fully ejected stylet at an
exposure time of 200 ns and a
framing rate of 1,430,000 fps. |
| Comments |
Researchers calculate a constant acceleration
(a=2×s/t^2) from 1.35×10^6 g up to
5.41×10^6 g (g = 9.81 m/sec2), which
is two orders of magnitude greater
than previous measurements (see BNID 102414). |
