The complex of potentials that appear during the massed electrical response of the retina to brief
flashes
of light (electroretinogram) is estimated by the equation N=8exp(-8t), where “t” stands for
dN/dt=64exp(8t)
time.
Determine
the speed of the cell destruction.
dN/dt=64exp(-8t)
dN/dt=-64exp(8t)
dN/dt=-64exp(-64t)
dN/dt=-64exp(-8t)
The complex of potentials that appear during the massed electrical response of the retina to brief
flashes
of light (electroretinogram) is estimated by the equation N=2exp(-2t), where “t” stands for
dN/dt=81exp(9t)
time.
Determine
the speed of the cell destruction.
dN/dt=81exp(-9t)
dN/dt=-81exp(9t)
dN/dt=-81exp(-81t)
dN/dt=-81exp(-9t)
