1.2.1 Examples

We looked at ``two toy neurons'' that are coupled together as an example:

$\displaystyle \left \{ \begin{array}{lc} \dot{v}_1 = -5v_1 + 17 \tan^{-1}(v1) -...
...  \dot{v}_2 = -v_2 + 4 \tan^{-1}(v1) -5 \tan^{-1}(v_2)  \end{array} \right.$    

We also looked at a pair of linear equations of the form:

$\displaystyle \left \{ \begin{array}{lc} \dot{v}_1(t) = a \cdot v_1(t) + b \cdo...
...  \dot{v}_2(t) = c \cdot v_1(t) + d \cdot v_2(t) + I_2  \end{array} \right.$    

With and without external inputs $ I_1,I_2$. We then saw that the equilibrium points of the linear system above (without external inputs) has the same behavior as the equilibrium point of the same system with external inputs.
