Neurons: The Cell Body and the Dendrites01:23

Neurons: The Cell Body and the Dendrites

6.3K
A typical nerve cell comprises three main components: the cell body, dendrites, and the axon. The cell body, also known as the soma or perikaryon, serves as the central biosynthetic hub housing a nucleus surrounded by cytoplasm containing organelles commonly found in most cells. Notably, Nissl bodies, clusters of the rough endoplasmic reticulum and free ribosomes responsible for protein synthesis, are distinctive features of the neuronal cell body. As neurons age, aggregates of a brown pigment...

Postsynaptic Potential (PSP)01:32

Postsynaptic Potential (PSP)

4.5K
Postsynaptic potential (PSP) refers to a change in the electrical potential of a neuron when neurotransmitters released by presynaptic neurons bind to postsynaptic receptors. This potential can either be excitatory, leading to depolarization and ultimately action potential generation, or inhibitory, leading to hyperpolarization and suppression of the postsynaptic neuron.
There are two types of receptors: ionotropic and metabotropic.
The ionotropic receptor is the membrane protein that has an...

Peripheral Nervous System: Ganglia and Nerves

4.5K
The Peripheral Nervous System (PNS) is a crucial component of the body's neural network, extending beyond the central nervous system (CNS) to bridge the gap between the CNS and the external environment. It encompasses nerves, ganglia, and sensory receptors.
Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...

Neuron Structure

17.3K
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...

Nervous Tissue: Neuron Types

5.5K
Neurons, the fundamental units of the nervous system, can be classified based on both their structural and functional characteristics.
Structurally, neurons are categorized into three main types: multipolar, bipolar, and unipolar (or pseudounipolar). Multipolar neurons, which are the most common type in the brain and spinal cord, as well as all motor neurons, possess multiple dendrites and a single axon.
Bipolar neurons, on the other hand, have one primary dendrite and one axon. They are...

Area of Science:

  • Computational Neuroscience
  • Theoretical Computer Science
  • Biologically Inspired Computing

Background:

  • Dendrites, previously considered passive, are now understood to perform mixed analog-digital computations and possess feedback mechanisms.
  • This biological insight offers a new paradigm for designing information processing systems.
  • Existing spiking neural P (SNP) systems utilize a storing-firing process.

Purpose of the Study:

  • To propose a new variant of neural-like P systems, termed dendrite P (DeP) systems.
  • To model the computational and feedback characteristics of dendrites within a formal system.
  • To investigate the computational power and universality of these DeP systems.

Main Methods:

  • Neurons in DeP systems simulate dendrite computational functions, employing a firing-storing process.
  • Neuron behavior is governed by abstracted dendrite rules, controlled by source neuron states.
  • The collaborative control capability of neurons in DeP systems is analyzed.

Main Results:

  • DeP systems demonstrate a collaborative control capability for neurons, differing from standard SNP systems.
  • It is proven that DeP systems are Turing-universal number generating and accepting devices.
  • A small universal DeP system comprising 115 neurons was constructed for function computation.
