    Necessary conditions for signal processing by resonant neurons
    (2001) Villacorta Atienza, José Antonio; Sánchez Jiménez, Abel; Panetsos Petrova, Fivos
    We study a mathematical model for information processing and coding by means of groups of resonant neurons. We conclude that incoming signals can be expressed by means of their Fourier series which coefficients are represented by the value of the membrane potential of the resonant neurons.

    Computational study of resonant neural behaviour in the presence of continuous signals
    (2001) Sánchez Jiménez, Abel; Villacorta Atienza, José Antonio; Panetsos Petrova, Fivos; Pérez de Vargas, Antonio; Rattay, Frank
    The resonant behaviour and the response preference to input signals of specific frequencies are well known properties of many neurons of the Central Nervous System. In the present communication we computationally evaluate a theoretical model of oscillating neurons and we prove that ensembles of neurons with a reduced variety of channels could make use of the fluctuations of their membrane potential to perform signal analysis.

    Tactile information processing in the trigeminal complex of the rat
    (Complex Dynamics and Fluctuations in Biomedical Photonics IV, 2007) Makarov Slizneva, Valeriy; Pavlov, Alexey N.; Tupitsyn, Anatoly N.; Panetsos Petrova, Fivos; Moreno, Ángel; García-González,, Víctor; Sánchez Jiménez, Abel; Tuchin, VV
    We study mechanisms of information processing in the principalis (Pr5), oralis (Sp5o) and interpolaris (Sp5i) nuclei of the trigeminal sensory complex of the rat under whisker stimulation by short air puffs. After the standard electrophysiological description of the neural spiking activity we apply a novel wavelet based method quantifying the structural stability of Bring patterns evoked by a periodic whisker stimulation. We show that the response stability depends on the puff duration delivered to the vibrissae and differs among the analyzed nuclei. Pr5 and Sp5i exhibit the maximal stability to an intermediate stimulus duration, whereas Sp5o shows "preference" for short stimuli.
