CA register

We continue to explore the properties of the  CA register . The proliferon consists of three processes (CA), a stem process (CA-1) which  keeps the unit alive, and two transient processes. At t-15 CA-2 was injured. Three of its border cells were removed, which ultimately killed it.


Injury initiated a death process, called apoptosis, which extended over 31 states. The next experiment starts with the same injury. At t = 30 CA-3 copied the CA-2 state. Apoptosis was initiated, and soon CA-3 also died. The copied structure was state 15  (30-15) of the apoptotic process, which illustrates that any state of the apoptotic process, copied by CA-3 would have led to its death.

The copied states contain  information for initiating apoptosis . Unlike memories in conventional computers  our register does not store a description of apoptosis. It initiates it. Our memory  does not store images or data, but actions,

We start again with a CA-2 injury. At t - 25 CA-2 stops aging and remains in apoptotic state-10 (25-10). At t-50. CA-3 copies this state, and dies at t-75. CA-2 also dies but not from apoptosis.   Since apoptosis is frozen at state-10, CA-2  dies from aging. When CA rests it utilizes age for its existence and age declines. The rate of decline is the negative of age accumulation rate in  an active CA. When age is exhausted CA-2 dies.


Memory is an active process which requires resources (age). CA-2 may be rescued in two ways. Either it  resumes accumulating age which  will alter its structure, and it will forget  its apoptotic state-10. Or it may get the required age from another process . In the first case it will soon die from apoptosis. In the second case it will remain frozen, and when activated it will also die from apoptosis. As CA-2 loses age, its structure changes (differentiation), and may no longer initiate apoptosis in the recipient CA-3.

The last experiment  starts with the injury at t-15. At t-25 CA-2 stops aging and remains in apoptotic state-10  At t-30 apoptotic state-10 is copied to CA-3. It  ages 10 time steps, which brings it to apoptotic state-20. It now  stores this state  till t-145. Meanwhile CA-2 loses age and dies. It is replaced by a zygote.  At t-95, CA-2 copies state-20 from CA-3 and soon dies to be replaced by a zygote. Despite a change in the structure  of state-20, it still induces apoptosis in CA-2.
