Analysis of the role of the low threshold currents IT and Ih in intrinsic delta oscillations of thalamocortical neurons
(Frontiers Research Foundation, 2015-05-07)
Thalamocortical neurons are involved in the generation and maintenance of brain rhythms associated with global functional states. The repetitive burst firing of TC neurons at delta frequencies (1-4 Hz) has been linked to ...
Synchronization Analysis in Models of Coupled Oscillators
(2020-01-01)
The present work deals with the analysis of the synchronization possibility in chaotic oscillators, either completely or per phase, using a coupling force among them, so they can be used in attention systems. The neural ...
Competition between persistent Na+ and muscarine-sensitive K+ currents shapes perithreshold resonance and spike tuning in CA1 pyramidal neurons
(Frontiers Research Foundation, 2017)
© 2017 Vera, Alcayaga and Sanhueza. Neurons from many brain regions display intrinsic subthreshold theta-resonance, responding preferentially to theta-frequency oscillatory stimuli. Resonance may contribute to selective ...
Recording gamma band oscillations in pedunculopontine nucleus neurons
(JoVE, 2016-09)
Synaptic efferents from the PPN are known to modulate the neuronal activity of several intralaminar thalamic regions (e.g., the centrolateral/ parafascicular; Cl/Pf nucleus). The activation of either the PPN or Cl/Pf nuclei ...
Refinement of neuronal synchronization with gamma oscillations in the medial prefrontal cortex after adolescence
(Public Library of Science, 2013-04)
The marked anatomical and functional changes taking place in the medial prefrontal cortex (PFC) during adolescence set grounds for the high incidence of neuropsychiatric disorders with adolescent onset. Although circuit ...
Bifurcations and multistability in the extended Hindmarsh-Rose neuronal oscillator
(2016-04-01)
We report on the bifurcation analysis of an extended Hindmarsh-Rose (eHR) neuronal oscillator. We prove that Hopf bifurcation occurs in this system, when an appropriate chosen bifurcation parameter varies and reaches its ...
Mechanisms and functions of respiration-driven gamma oscillations in the primary olfactory cortex
