Hexadirectional orientation stability

1. Retrosplenial absolute-orientation stability is associated with hexadirectional orientation stability in humans.

   “Finally, retrosplenial absolute-orientation stability was associated with left-pmEC orientation stability”

   Weaker navigation signals may reflect instability in older adults

1. Hexadirectional orientation stability predicts object location memory in humans.

   “In left-pmEC, higher orientation stability also predicted better object-location memory.”

1. Hexadirectional orientation stability is associated with hexadirectional signal strength in humans.

   “Hexadirectional orientation stability, the cross-run reproducibility of direction-specific activity patterns, was associated with hexadirectional signal strength in the posterior-medial-entorhinal-cortex (pmEC).”
