    Figure 1. Neuron anatomy for network model. The generation of the action potential is called the "firing". The firing neuron described above is called a spiking neuron. We will model the electrical circuit of the neuron in Section 3.6. There are two types of spiking neurons.

  3. Biological neuron model - Wikipedia

    en.wikipedia.org/wiki/Biological_neuron_model

    Biological neuron models, also known as spiking neuron models, [1] are mathematical descriptions of the conduction of electrical signals in neurons. Neurons (or nerve cells) are electrically excitable cells within the nervous system , able to fire electric signals, called action potentials , across a neural network.

  4. Axon - Wikipedia

    en.wikipedia.org/wiki/Axon

    [6] [7] One function of the initial segment is to separate the main part of an axon from the rest of the neuron; another function is to help initiate action potentials. [8] Both of these functions support neuron cell polarity , in which dendrites (and, in some cases the soma ) of a neuron receive input signals at the basal region, and at the ...

  5. Dendritic spike - Wikipedia

    en.wikipedia.org/wiki/Dendritic_spike

    Schematic of a chemical synapse between an axon of one neuron and a dendrite of another. Spike-timing-dependent plasticity (STDP) refers to the functional changes in a neuron and its synapse due to time dependent action potentials. When an action potential reaches the pre-synaptic membrane it opens voltage-gated calcium channels causing an ...

  6. Neural oscillation - Wikipedia

    en.wikipedia.org/wiki/Neural_oscillation

    The model is based on data from the squid giant axon and consists of nonlinear differential equations that approximate the electrical characteristics of a neuron, including the generation and propagation of action potentials. The model is so successful at describing these characteristics that variations of its "conductance-based" formulation ...

  7. Axon guidance - Wikipedia

    en.wikipedia.org/wiki/Axon_guidance

    Axon guidance (also called axon pathfinding) is a subfield of neural development concerning the process by which neurons send out axons to reach their correct targets. Axons often follow very precise paths in the nervous system, and how they manage to find their way so accurately is an area of ongoing research.
