dendrite

Examples of dendrite in the following topics:

• Introducing the Neuron

  • Although some neurons do not have any dendrites, other types of neurons have multiple dendrites.
  • Dendrites can have small protrusions called dendritic spines, which further increase surface area for possible connections with other neurons.
  • The synapse is the chemical junction between the axon terminals of one neuron and the dendrites of the next.
  • One neuron's axon will connect chemically to another neuron's dendrite at the synapse between them.
  • Electrically charged chemicals flow from the first neuron's axon to the second neuron's dendrite, and that signal will then flow from the second neuron's dendrite, down its axon, across a synapse,  into a third neuron's dendrites, and so on.

• Habituation, Sensitization, and Potentiation

  • In neural communication, a neurotransmitter is released from the axon of one neuron, crosses a synapse, and is then picked up by the dendrites of an adjacent neuron.
  • This image shows the way two neurons communicate by the release of the neurotransmitter from the axon, across the synapse, and into the dendrite of another neuron.
  • Communication between neurons occurs when the neurotransmitter is released from the axon on one neuron, travels across the synapse, and is taken in by the dendrite on an adjacent neuron.

• Neural Networks

  • The method through which neurons interact with neighboring neurons usually consists of several axon terminals connecting through synapses to the dendrites on other neurons.
  • Neurons interact with other neurons by sending a signal, or impulse, along their axon and across a synapse to the dendrites of a neighboring neuron.

• Genetic Basis of Intelligence and Learning

  • It looks at what environmental, emotional and social situations are best in order for new information to be retained and stored in the brain via the linking of neurons, rather than allowing the dendrites to be reabsorbed and the information to be lost.

• Network Models of Memory

  • As neurons form connections with each other through their many dendrites, they can form complex networks.

• Cerebral Cortex

  • Gray matter is the mass of all the cell bodies, dendrites, and synapses of neurons interlaced with one another, while white matter consists of the long, myelin-coated axons of those neurons connecting masses of gray matter to each other.

• Other Steps

  • Dendrites, which are extensions of neurons, receive the impulse and allow the synapse to increase in strength; this is known as long-term potentiation.

• Mechanics of the Action Potential

  • Presynaptic cell: a specialized area within the axon of the giving cell that transmits information to the dendrite of the receiving cell.
  • Postsynaptic cell: a specialized area within the dendrite of the receiving cell that contains receptors designed to process neurotransmitters.

• Biology of Emotion

  • Individuals suffering from posttraumatic stress disorder (PTSD) show marked reductions in volume in several parts of the hippocampus, which may be the result of decreased levels of neurogenesis and dendritic branching (the generation of new neurons and the generation of new dendrites in existing neurons, respectively) (Wang et al., 2010).
