orientation selectivity
[/ˌɔːrɪənˈteɪʃən sɪˈlɛktɪvɪti/]
nounfemininepl: orientation selectivities
seletividade de orientação
1. The neural property of sensory neurons, particularly in visual cortex, to respond preferentially to stimuli oriented at specific angles
The orientation selectivity of neurons in V1 allows them to detect edges and lines at particular angles in the visual field.
A seletividade de orientação dos neurônios no V1 permite que eles detectem bordas e linhas em ângulos particulares no campo visual.
2. In neuroscience, the ability of cortical cells to show maximum firing rates for stimuli presented at a preferred orientation while showing minimal response to orthogonal orientations
The orientation selectivity of simple cells varies with the stimulus parameters used in the experiment.
A seletividade de orientação das células simples varia com os parâmetros do estímulo utilizados no experimento.
This is a specialized neuroscience term used predominantly in academic and research contexts. It originated from Hubel and Wiesel's Nobel Prize-winning work on visual cortex in the 1960s. The term is used identically in both Brazilian Portuguese and English scientific communities with no significant regional variations.
