Comparison of dLGN orientation selectivity in different species

	Mouse	Cat	Macaque
Orientation-selective cells (based on OSI)	59% (OSI >0.33)a	26–41% (OSI >0.33)b,c	“Only a small number of cells”d
	39% (OSI >0.5)a	5–8% (OSI >0.5)b,c
Distribution of the preferred orientation	Vertical biasa,e,f	Horizontal biasc	Horizontal biasd
Independent of cortical feedback	Yesa	Yesc
Preferred orientation predicted from the elongated RF	Yesa,f	Yesg	Yesd
Orientation-selective cells that have circular RFs	Yesa,f
Orientation-selective to static stimuli	Yesa		Yesd
Largely similar orientation tuning at different contrasts	Yesa
