Does neuron have weight?
If you look at the 2nd equation under "Propagation function"

$p_{j}(t)=\sum _{i=1}^No_{i}(t)w_{ij}+w_{0j}$

The $w_{0j}$ is the constant (bias), so it's reasonable to write that the $w_{ij}$ weights are associated with the connections, and the $w_{0j}$ is a weight associated with the nueron itself.

Additionally if you assume $o_{0}(t)=1$ then you can rewrite the equation above as

$p_{j}(t)=\sum _{i=0}^No_{i}(t)w_{ij}$

(i.e. note the sum is from 0 to N, not 1 to N)

When you do this it no longer really makes sense to make a distinction between a "weight" and a "bias".
