Delay activity

[noha]

Hello,

I am translating a book called Models of Mind by Grace Lindasy and I want to want to make sure of some thing  Chapter 4:

Does  delay activity in the following sentence is the same as delay period activity which means:
A simple definition of delay-period activity is the activity observed during the delay period. Therefore, delay-period activity can be observed in any task condition if the task includes the delay period. And, delay-period activity can be observed in any brain areas

But if delay activity occurs without any external input from an image then that sustained input must come from neighbouring neurons.
Thus, delay activity can only be generated by a network of neurons working together, the connections between them conspiring to keep the activity alive.

It seems they are the same event / phenomenon being described, yes... During the period of delay, this is the activity taking place. One describes ANY activity in this time period, the other describes only those happening within that same time period, but without any inputs from outside
