Synaptic Signaling01:12

Synaptic Signaling

79.5K
Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.

Synaptic Signaling

6.7K
Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.
The presynaptic neuron fires an action potential that...

Plasticity00:58

Plasticity

3.1K
Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...

Plasticizers01:31

Plasticizers

370
Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

Protein Networks02:26

Protein Networks

4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Plastic Behavior01:21

Plastic Behavior

577
A material's elastic behavior is characterized by the disappearance of stress once the load is removed, allowing the material to return to its original state. However, when stress surpasses the yield point, yielding commences, marking the onset of plastic deformation or permanent set. This change from elastic to plastic behavior is influenced by the peak stress value and the duration before the load is removed. An intriguing observation occurs when a specimen is loaded, unloaded, and...

Area of Science:

  • Computational Neuroscience
  • Neuroscience
  • Systems Neuroscience

Background:

  • Excessive neuronal synchronization in the cerebral cortex is linked to neurological disorders like Parkinson's disease, epilepsy, and essential tremor.
  • Understanding and controlling pathological synchronized rhythms is crucial for developing effective treatments.

Purpose of the Study:

  • To numerically explore methods for eliminating pathological synchronized rhythms in interacted bursting neurons within a modular neuronal network.
  • To investigate the efficacy of synaptic plasticity and nonlinear delayed feedback control in suppressing neuronal synchronization.

Main Methods:

  • Construction of a modular neuronal network model.
  • Application of a modified Oja's learning rule for synaptic plasticity.
  • Implementation of nonlinear delayed feedback control, including differential and direct feedback control.

Main Results:

  • Synaptic plasticity with a large learning rate effectively suppresses bursting synchronization.
  • Nonlinear delayed feedback control (differential and direct) significantly reduces synchronized bursting when parameters are tuned.
  • Distinct control domains were identified for differential (semi-elliptical) and direct (fan-shaped) feedback control.

Conclusions:

  • Both synaptic plasticity and nonlinear delayed feedback control are effective strategies for mitigating pathological neuronal synchronization.
  • The findings provide a numerical framework for understanding and potentially treating neurological disorders associated with excessive neuronal synchrony.
