Learning to navigate plays an integral role in the survival of humans and other animals. Research on human navigation has largely focused on how we deliberately map out our world. However, many of us also have experiences of navigating on "autopilot" or out of habit. Animal models have identified this cognitive mapping versus habit learning as two dissociable systems for learning a space-a hippocampal place-learning system and a striatal response-learning system. Here, we use this dichotomy in humans to understand variability in navigational style by demonstrating that brain activation during spatial encoding can predict where a person's behavior falls on a continuum from a more flexible cognitive map-like strategy to a more rigid creature-of-habit approach. These findings bridge the wealth of knowledge gained from animal models and the study of human behavior, opening the door to a more comprehensive understanding of variability in human spatial learning and navigation.

Kujifunza jinsi ya kusafiri kwa meli ni muhimu sana kwa wanadamu na wanyama wengine ili waendelee kuishi. Utafiti kuhusu jinsi wanadamu wanavyosafiri umezingatia hasa jinsi tunavyochora ramani ya ulimwengu wetu kimakusudi. Hata hivyo, wengi wetu pia tumepata uzoefu wa kuendesha ndege kwa "autopilot" au kwa sababu ya zoea. Mifano ya wanyama imebainisha ramani hii ya utambuzi dhidi ya kujifunza tabia kama mifumo miwili ya kutenganisha kwa kujifunza nafasi - mfumo wa kujifunza mahali pa hippocampal na mfumo wa kujifunza majibu ya striatal. Katika utafiti huu, tunatumia dichotomy hii kwa wanadamu kuelewa kutofautiana katika mtindo wa urambazaji kwa kuonyesha kwamba uanzishaji wa ubongo wakati wa encoding ya nafasi unaweza kutabiri ambapo tabia ya mtu huanguka kwenye mfululizo kutoka kwa mbinu ya ramani ya utambuzi ya kubadilika zaidi hadi kwa mbinu ya tabia ya kiumbe. Matokeo haya yanaunganisha utajiri wa maarifa yaliyopatikana kutoka kwa mifano ya wanyama na utafiti wa tabia ya kibinadamu, na kufungua mlango kwa uelewa kamili wa mabadiliko katika kujifunza na urambazaji wa nafasi ya binadamu.
