the meaning of '
the firing pattern'
The passage below is from ‘the Blank Slate’ by Steven Pinker.
http://evolbiol.ru/blankslate/blankslate.htmSo even an extreme innatist need not believe that the brain differentiates itself by the equivalent of GPS coordinates in the skull, following rules like “If you are between the left temple and the left ear, become a language circuit” (or a fear circuit, or a circuit for recognizing faces). A developmental program may be triggered in a part of the developing brain by some combination of the source of the stimulation, the firing pattern, the chemical environment, and other signals. The end result may be a faculty that is seated in different parts of the brain in different people. In this passage I cannot figure out what the underlined '
the firing pattern' means.
I googled out, but there isn't any specific clue or examples to work out the meaning.
Can you help me?
Regards.
