Neurons
- The academic community does not have a complete understanding
of what mammalian neurons do.
- However, by and large the community agrees that:
- Neurons fire if their activation passes a threshold.
- When a neuron fires it sends activity across its synapses giving
activation to other neurons.
- They're leaky integrators. If they fire they lose all activation,
if they don't some leaks away.
- They fatigue. The more they fire, the higher the threshold. Rest
allows recovery.
- Some neurons are excitatory, some are inhibitory, but none are
both.
- Synapses tend to connect to nearby neurons.
- There are different types of neurons but not that many (say 50)
