Input Signals

Single-stimulus input

When runing a network simulation via csim('simulate',...); one can specify input signals like in the command

    » csim('simulate',Tsim,S);

where S is a struct array with the following fields:

• S(i).idx : array of handles of objects which should receives this signal

• S(i).spiking : binary flag (0/1) which determines if S(i).data should be interpreted as spike times or as an analog signal

• S(i).dt : time discretization; for analog signals (S(i).spiking=0) only

• S(i).data : signal data: vector of the analog values (S(i).spiking=0) or spike times (S(i).spiking=1)

Note that csim('simulate',...); accepts an arbirary number of such struct arrays. See documentation of the simulate command.

Multi-stimulus input

When runing a network simulation via csim('simulate',...); one can specify a multi-stimulus input S like in the command

    » R = csim('simulate',Tsim,S);

where S is a n x 1 struct array of the form S(i).channel which describes the i-th stimulus. S(i).channel has the structure as described above.

If such multi-stimulus input is specified CSIM will simulate the current network with each of the n stimuli where at the beginning of each stimuli the network is reset to t=0. The return argument R contains the recorded information of all n simulations (see Section 3.2.2).
