Experimental and theoretical investigation of computational properties of red nucleus neuron

Microelectrode analysis of red nucleus (RN) neurons was used to study the regulatory influences on an axiosomatic input from a cerebellar nucleus interpositus and on an axodendritic input from a sensorimotor area of a cortex. To bring together these experimental data and previous theoretical results on detector properties of RN neurons, an improved model neuron with double-barrier synaptic elements has been developed. Based on results of simulation experiments with the model, several quantitative generalizations have been developed as aids to an extended understanding of the computational properties of the RN neuron
