This section introduces a simple method to solve the sound localization problem with only learnable delays. Additionally, it discusses a method that learns both weights and delays, introduced in {cite:p}`hammouamri2024learning`.

Learning synaptic delays with weights enables the visualization of the 'receptive field' of postsynaptic neurons, as illustrated in [](#rf). Five randomly chosen neurons from the hidden layer are plotted, revealing clear spatiotemporal separation of excitation and inhibition.

Receptive fields of 5 randomly chosen postsynaptic neurons. The x-axis represents the presynaptic neuron index, while the y-axis displays the learned delay value. Colors indicate the sign of the weight (excitation or inhibition), with transparency denoting magnitude.
