From: Transformation of the head-direction signal into a spatial code
HD neurons in the PoSub, but not in the ADn, integrate both allocentric (vestibular) and egocentric (self-centered) information to build an unbiased spatial code. a Egocentric modulation of HD neurons in the PoSub correlate with border modulation in for PoSub HD neurons. b Same as a for HD cells of the ADn. c Correlation between egocentric modulation of HD neurons in the PoSub and the amount of unbiased spatial information. d Correlation of the maximal border modulation coefficient of each neuron with the coefficient associated with the opposite wall (left) or with the adjacent walls (right; the average of the two border coefficients is considered in this case). e Schematic diagram of the transformation of an allocentric HD signal into a spatial code for border by a combination with an egocentric signal
