Title: The meaning of a sentence in McCulloch and Pitts' paper Post by: Noha Salah on Jan 12, 2023 Hello,
I'm translating a book called Models of mind by Grace Lindasy. and I want to know What does it mean by its adequate stimulus: McCulloch and Pitts go on to explain how these biological details are congruent with Boolean logic. The core of their claim is that the activity state of each neuron – either firing or not – is like the truth value of a proposition – either true or false. In their own words, they ‘conceive of the response of any neuron as factually equivalent to a proposition which proposed its adequate stimulus’. By ‘its adequate stimulus’ they are referring to something about the world. Title: Re: The meaning of a sentence in McCulloch and Pitts' paper Post by: bio_man on Jan 12, 2023 "adequate stimulus" means that a certain threshold needs to be meet for the neuron to fire. For example, if an insect lands on your skin, you may not sense it because the neurons on your skin need to reach a higher threshold to activate. Here, the insect does not serve as an "adequate stimulus".
Does that make sense? |
