Neuronal tuning refers to the hypothesized property of brain cells by which they selectively represent a particular type of sensory, association, motor, or cognitive information. Some neuronal responses have been hypothesized to be optimally tuned to specific patterns through experience. Neuronal tuning can be strong and sharp, as observed in primary visual cortex (area V1) (but see Carandini et al 2005 ), or weak and broad, as observed in neural ensembles. Single neurons are hypothesized to be simultaneously tuned to several modalities, such as visual, auditory, and olfactory. Neurons hypothesized to be tuned to different signals are often hypothesized to integrate information from the different sources. In computational models called neural networks, such integration is the major princip

  • 神经元调谐(英文:neuronal tuning),是指神经元有选择地表示一种感觉、協同、运动、认知等信息的特性。通过经验,神经元反应被调谐为最优的特定范式。神经元调谐可以是强而集中的,如V1区;也可以是弱而宽泛的,如神经元集群。单个神经元可能会同时对多种基本感觉调谐,如视觉、听觉、嗅觉。这种神经元通常对多个感觉起整合作用。在神经网络中,这一整合是操作(认知加工)的主要原则。 在视觉、听觉、嗅觉、躯体感觉和记忆系统中,都可以看到神经元调谐的现象。 (zh)

Les neurones que estan sintonitzades a diferents senyals sovint integren informació procedent de diferents orígens. En les xarxes neurals, aquesta integració és la principal forma d'operar. Els millors exemples de sintonització neuronal es poden observar en els sistemes de memòria visual, auditiva, olfactiva i somatosensorial. (ca)

Neurons hypothesized to be tuned to different signals are often hypothesized to integrate information from the different sources. In computational models called neural networks, such integration is the major principle of operation. The best examples of neuronal tuning can be seen in the visual, auditory, olfactory, somatosensory, and memory systems, although due to the small number of stimuli tested the generality of neuronal tuning claims is still an open question.

  • La sélectivité neuronale est la modulation de l'activité électrophysiologique d'un neurone en fonction du stimulus sensoriel (e.g., un son) ou, plus généralement de toute autre information traitée par le système nerveux. Un exemple classique de sélectivité neuronale est le mode de réponse des neurones dits simples du cortex visuel primaire. Le taux de décharge de potentiels d'action de ces neurones varie en fonction de l'orientation des stimuli visuels : chaque neurone répond de façon maximale pour les lignes ayant une orientation particulière. Par exemple, tel neurone présentera une réponse maximale pour les stimuli visuels orientés verticalement, tandis qu'un autre répondra surtout pour les stimulations visuelles orientées à 30° par rapport à l'horizontale et très peu pour les orientations différentes. * Portail des neurosciences (fr)
