Developing recognition of faces and places

Hannah Bayer
2007 Nature Neuroscience  
Normal behavior develops as a function of experiences, such as those associated with adaptive reward-based learning, which is the essential process subverted by addiction 11 .  ...  A recent functional magnetic resonance imaging study of addicted smokers showed that cues related to smoking elicit neural activity in regions linked to attention, memory, emotion and motivation 13 .  ...  The authors used fMRI to identify areas of the occipito-temporal cortex that preferentially respond to objects (lateral occipital complex, LOC), faces (fusiform face area, FFA) or places (parahippocampal  ...
