PYRAMIDAL NEURON [4 records]

Record 1 2013-12-10

English

Subject field(s)
  • Cytology
DEF

A type of pyramidal neuron within the hippocampus that is associated with spatial navigation and that fires to a particular place field, which corresponds to a specific location in space.

CONT

Place cells generate mental representations that are used for navigation and self-location. Place cells work with other types of neurons in the hippocampus to perform this kind of spatial processing.

French

Domaine(s)
  • Cytologie
DEF

Neurone de l'hippocampe dont le champ récepteur (dit champ de lieu) est défini par un lieu donné sur une carte cognitive.

CONT

Pour nous repérer dans un lieu, notre cerveau met en marche des neurones spécialisés, dits cellules de lieu.

Record 3 1998-03-03

English

Subject field(s)
  • Nervous System
  • Special-Language Phraseology
CONT

A large proportion of the spines of pyramidal cells-the major class of neuron that projects out of the cortex-receive asymmetric contacts from the axons of another cell whose point of origin has not yet been identified but which is thought to carry signals from other cortical areas. Those asymmetric contacts probably have an opposite, excitatory effect.

French

Domaine(s)
  • Système nerveux
  • Phraséologie des langues de spécialité
CONT

Une forte proportion des épines dendritiques des cellules pyramidales - le type principal de cellules se projetant hors du cortex - établit des contacts asymétriques avec les axones d'autres cellules dont l'origine est inconnue mais qui semblent apporter des informations issues d'autres aires corticales. Ces contacts asymétriques ont probablement un effet excitateur.
