Stability of Antiphase Oscillations in a Network of Inhibitory Neurons

SIAM Journal on Applied Dynamical Systems, 2015
The authors study antiphase oscillations in a network of two mutually inhibitory neurons using geometric singular perturbation theory. They use slow/fast analysis to derive a two-dimensional map, a stable fixed point of which corresponds to a stable antiphase periodic orbit of the full network.

Inhibitory neurons and the asymmetric shape of neuronal avalanches

Physical Review E
In the last twenty years neuronal avalanches have been deeply investigated, both experimentally and numerically, also framing the results in the context of the avalanche scaling theory. In particular the avalanche shape has recently received a wide attention, also because the existence of a universal shape is an indication of the brain acting at a ...

Characteristics of cortical inhibitory neurons

Neurophysiology, 1975
Spikes were recorded extracellularly and IPSPs intracellularly from auditory cortical neurons of cats immobilized with D-tubocurarine in response to stimulation of geniculo-cortical fibers. Fibers whose stimulation induces IPSPs in auditory cortical neurons mainly have low thresholds. When two stimuli, each of which separately evoked an IPSP of maximal

Inhibitory neurons in the right place

Science, 2019
Neurodevelopment Disruption of γ-aminobutyric acid–mediated (GABAergic) interneuron migration is implicated in neurodevelopmental disorders such as autism spectrum disorder and schizophrenia. Su et al. found that dopamine induced the association of the dopamine receptor D1R with the guanosine triphosphatase–activating protein SynGAP.

Irregular behavior in an excitatory-inhibitory neuronal network

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2010
Excitatory-inhibitory networks arise in many regions throughout the central nervous system and display complex spatiotemporal firing patterns. These neuronal activity patterns (of individual neurons and/or the whole network) are closely related to the functional status of the system and differ between normal and pathological states.

Synaptic Integration in Cortical Inhibitory Neuron Dendrites

Neuroscience, 2018
Cortical inhibitory interneurons have a wide range of important functions, including balancing network excitation, enhancing spike-time precision of principal neurons, and synchronizing neural activity within and across brain regions. All these functions critically depend on the integration of synaptic inputs in their dendrites.

Burst synchronization of inhibitory spiking neuronal networks

2015 11th International Conference on Natural Computation (ICNC), 2015
Synchronized firing of spiking neuronal systems is considered to be crucial in the brain signal transmission and coding. In this paper, we incorporate a slow calcium ion channel into the classical Hodgkin-Huxley neuronal model and use it to construct spiking neuronal networks with heterogeneous neurons coupled by delayed chemical synapses, then explore

On the development of inhibitory projection neurons

2023
High precision is critical for normal neural circuit function, but that precision is not innate. The location, strength, and number of inputs in a neural circuit are modified in early postnatal development in a process called refinement. The refinement of long-range excitatory projections is well-known, but less is known about the refinement of long ...

Inhibitory Neurons in the Auditory Brainstem

2011
Most chapters in this volume address the function of the major excitatory synapses in the lower auditory pathways, with respect to coincidence detection, the ion channels that determine neuronal firing, and the control of excitation through modulation and plasticity.
