Long-Term Memory Neural Circuits, Fast and Precise - Brain Theory from a Circuits and Systems Perspective - page 146

(b) Randomize the names and then search from the top, is recall faster or
slower? How many trials are required for your new list? (HINT: Generally
less than 7)
7. Provide an example of recall that is modeled after a classic car, in which you
remember the chrome hood ornament and the red and white two-tone body but
not the other features of the car. (HINT: Trace the recall process and signals in a
four-cell model as done in the chapter's example)
Multiwrite Circuits
8. How is memorization enabled using the model of this chapter? (HINT: By
rehearsal of an image that is not yet memorized)
9. During memorization how are multiple copies of the same image avoided?
(HINT: a lockout signal is generated by the first return)
10. Devise a way to obtain a Hit signal from memory. (HINT: Refer to the circuits
given in this chapter, especially Lout and Rout)
11. Devise a way to obtain a NoHit signal from memory. (HINT: A circuit for this
has not been given, so it is up to the student to create one; perhaps use some sort
of timer that is stopped by a hit, but which otherwise sends out a NoHit signal
after a certain delay)
Simulated Qubits in Savant Memorization
12. Describe briefly the difference between memorization and learning as
portrayed in this chapter. (HINT: Memorization is instant, learning requires
time for synaptic development)
13. Provide a brief explanation of how a gifted savant can quickly memorize an
entire topic (HINT: Rehearsal filters enable state machine learning using fewer
rehearsals)
14. Sketch a plan for a rehearsal filter that detects when steps in a procedure are
repeated three times. (HINT: Use three toggle units in a cascade)
