15 & 16 - Brains & Computing Flashcards
1
Q
Do neuroscientists look at each individual neurons impact?
A
No, ignore many details of each neuron, and typically builds simulation of neural network
2
Q
What is the role of modelling/simulation in science?
A
If we can build it, means we can understand it well.
Typically, strips away irrelevant details, and makes it more familiar
3
Q
What suggests the brain uses a connectionist/neural network model?
A
Each neuron cannot do much by itself.
Each synapsing cell is excitatory or inhibitory, and it’s the temporal and spatial summation that depends if threshold is reached.
4
Q
How is the brain represented in a simplified brain model?
A
Represent the ability of neurons to make the next one fire, ignoring details of neurotransmitters or membrane potential
