Precise mapping of the neural landscape underlying recognition memory

Recognizing objects is fundamental to the construction of episodic memories and the interpretation of our daily experiences. However, studies investigating the neural basis of recognition memory have traditionally employed a limited number of exemplars or trials, failing to capture the complexity and richness of real-world cognition. Furthermore, while prior work has highlighted that large parts of the brain are sensitive to recognition memory1,2, the precise topographical contributions of these regions remain unclear. To address these gaps, here we conducted a continuous recognition memory experiment using dense scanning at ultra-high field 7T fMRI. Participants were tested on their ability to recognize repetitions of 1280 unique images allowing for high-resolution mapping of the neural mechanisms underlying recognition memory.
