Neural Circuits

Neural Circuits

Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

Neuron Structure

Neurons are the main type of cell in the nervous system that generate and transmit electrochemical signals. They primarily communicate with each other using neurotransmitters at specific junctions called synapses. Neurons come in many shapes that often relate to their function, but most share three main structures: an axon and dendrites that extend out from a cell body.
Structure and Function of Neurons
The neuronal cell body—the soma— houses the nucleus and organelles vital to...

Neuronal Communication

Neuronal Communication

Neurons, the fundamental units of the brain and nervous system, communicate through complex electrochemical signals that underpin all cognitive and bodily functions. This communication is primarily facilitated by a process involving the generation and propagation of an action potential along the axon of the neuron. When the internal electrical charge of a neuron surpasses a certain threshold, an action potential is triggered. This rapid change in voltage travels swiftly along the axon to the...

Protein Networks

Protein Networks

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,...

Area of Science:

Neuroscience
Network Science
Systems Biology

Background:

Understanding neuronal network dynamics is crucial for neuroscience.
Quantifying network observability is key to interpreting experimental data.

Purpose of the Study:

To quantify the observability of small neuronal networks (3 nodes).
To investigate how topology, measured nodes, and nodal dynamics affect observability.

Main Methods:

Analysis of network observability metrics for different connection topologies and symmetries.
Evaluation of linear and nonlinear nodal dynamics.
Assessment of observability based on the choice of measured nodes.

Main Results:

Observability metrics varied over several orders of magnitude based on network topology.
Network symmetry reduced observability when measurements were taken from confounded nodes.
Nonlinear dynamics generally decreased average network observability, limiting full information to specific phase space regions.

Conclusions:

Small neuronal networks are partially observable.
Limited measurements can potentially reconstruct network dynamics.
Future experimental work is needed to validate these findings for network control.
