This model package provides NEURON codes associated with paper:
Vasilkov V. A. and Tikidji-Hamburyan R. A.(2012) 
Accurate Detection of Interaural Time Differences by a Population of Slowly Integrating Neurons.
Phys. Rev. Lett. 108, 138104. 

Scripts in this folder were used to produce Fig.3c of the paper.

Any questions for implementing the model should be directed to

	every script produces a 'comma separated values' file(csv) with
	population-rate transfer function for 10000 Hodgkin-Huxley neurons
	model, with:
		gsyngrad - synaptic conductances gradients
		delaygrad - delay lines gradients 
		jitter - jitter in pathways
		noisecur - neuron intrinsic noise current
	scan11 / scan55 means that population-rate transfer function was tested 
		within [-1, 1]ms or [-5, 5]ms respectively.
	step - indicates ITD step for testing mesh in selected range. 

rgi.mod - mechanisms for noise current. For better performance, please
	use Ted Carnevale's InNp.mod for future versions.

hhcell.hoc - template for standard Hodgkin-Huxley neuron model with noise
	current. WARNING: To use scripts with thread mode, one must include
	independent random number generator in this template .

main.hoc - functions to run simulation iteratively and obtain population-rate
	transfer function. DON'T run this file. See Scripts above.

csv2dat.py - simple python script, to convert csv to standard two 
	columns dat file.
