chapter explores possibilities for a specific type of toggled arithmetic necessary
for the prioritization of memory returns.

Self-Study Exercises
(If you desire to keep a record of your efforts, please show a couple of logical steps
leading to the answers.)
Long-Term Potentiation
1. Assume a receptor membrane pulse (instigated by sodium and other ions) to
have a steady value of 50
A/cm 2 and assume that the pulse is 200
μ
μ
s wide.
F/cm 2 .
Assume that receptor membrane capacitance is 1
μ
(a) Calculate the change in membrane voltage. (ANS. 10 mV)
(b)
Initially membrane voltage is at rest at 70 mV. Assume that it can be
triggered to provide a regular neural pulse if voltage exceeds 55 mV. Does
it trigger? (ANS. No because the voltage raises only to
60 mV)
(c) Assume LTP to a level of 10 mV above the rest voltage of
70 mV. Does
the membrane produce a neural pulse? (ANS. Yes because with LTP it is
resting at
60 mV. An additional 10 mV causes voltage to exceed
55 mV,
the threshold for triggering)
Multivibratation
2. Assume a pulse width of 1 ms, OR gate delay of 2 ms, and a feedback loop delay
of 10 ms.
