Many daily activities that we perform are result of inbuilt oscillatory circuits in our body. For example walking, breathing, heart beat, blinking, etc. The coding and decoding of stored memory also happen via controlled oscillations. The link http://en.wikipedia.org/wiki/Neural_oscillation contains information about neural oscillations. It says in here that a single neuron, an ensemble of neurons and activity of brain may exhibit synchronised oscillations. It is also said that these oscillatory circuits can control all the parameters of oscillations i.e. frequency, phase and amplitude.While above are true for neurons as a part of bigger systems, my question is related to study of isolated neurons.
There are many instances of studies of artificial neural circuitary created on a customized substrate(Micro Electrode Array) by masking techniques. Also there are loads of ongoing research to study the simple neural circuits in temporal and spatial domain by electrical interfacing of semiconductor and nerve cells using Field Effect Transistor(FET).
I want to know if these kind of oscillations are unique to some special kinds of neuron? Is the control of oscillation parameter possible in every neurons and isolated neurons? Can a neuron or any other cell exhibit change in action potential independently? Do other cells except neuron and pacemaker cells exhibit oscillation? Can a single neuron exhibit memory?
Can a simple circuit like below generate oscillations?
Suppose I culture the neurons on a substrate in a controlled way such that one neuron is connected to only one other neuron in a linear fashion and the last neuron is connected to first. Assuming we supply the ions if there is loss, can a clock pulse of varying frequencies be generated, where the frequency is the function of the no. of intermediate neurons and their length.
It would be a great help if somebody can provide information about softwares to simulate simple neural circuits (If available).
