Complete examples

single neuron

• script trunk/examples/single_neuron/CRF_neuron_vs_signal.py
• results illustrate that when you increase noise, the CRF response gets smoothed:

simple retina

• this is a dummy retina based on the previous example to illustrate several aspects of NeuroTools
• script trunk/examples/retina/retina.py

effect of noise

• script trunk/examples/retina/benchmark_noise.py
• Spontaneous acitvity to different levels of input noise:

effect of increasing the Signal-to-Noise Ratio

• script trunk/examples/retina/benchmark_linear.py
• For a given level of noise, now increasing the the signal-to-noise ratio. Note that since we use the same seed for the noise at different contrasts, spontaneous activity is identical because the simulation is deterministic. Note also, that it is also true after stimulation due to the limited "memory'" of the system and to the dynamical stability of this fibers (this would in general not be true for chaotic regimes in random recurrent networks).

showing an image to the retina

• script trunk/examples/retina/benchmark_retina.py
• In this simple retina, the input is shown between instants t=1s and t=3s, which may be observed in the middle plot, where we have shown separately ON and OFF cells in the central sub-field. Average spatial distribution of output for ON and OFF cells is shown in the right showing as expected the relative transmission of input information.
