Oh this is one of my favorite territories. Seeing “amygdalae” just gave me a happy chill. Never used the plural form.
I call it the “push from the amygdala”. One of my favorite “brain circuits” (to stick with the computer/brain metaphor, which is hard to avoid using ’cause it’s handy) – is the way the amygdala can give a stronger ‘push’ to the prefrontal cortex than the very weak way the prefrontal cortex can give back to the amygdala.
Hence: your reasoning is driven by emotion, to put it simply.
You can use your reasoning to control your emotion but the connection is … wispier and takes training to strengthen the connection.
That’s my simplified take on it.
Somewhere in my files I have the relative speeds (more data metaphors) for the amygdala –> prefrontal cortex vs the prefrontal cortex –> amydala. It’s a striking difference and explains a lot for me.
