The BB model explains spatial cognition in terms of interactions between specific neuronal populations, providing a common computational framework for the human neuropsychological and in vivo animal electrophysiological literatures.
Grid-cell maps can be aligned to both local and remote reference frames, suggesting that they provide a metric for space beyond the navigationally accessible boundaries of the local environment.
Mathematical modeling suggests that grid cells in the rodent brain use fundamental principles of number theory to maximize the efficiency of spatial mapping, enabling animals to accurately encode their location with as few neurons as possible.
Complementary neural codes in frontal and visual cortex support a role for feedback signals in the representation and recognition of partially occluded objects.
Functional magnetic resonance imaging performed while people imagined directions from stationary viewpoints supports theories suggesting that spatially tuned cells such as grid cells underlie mental simulation for future thinking.
Random fluctuations in neuronal firing may enable a single brain region, the medial entorhinal cortex, to perform distinct roles in cognition (by generating gamma waves) and spatial navigation (by producing a grid cell map).
The anterior cingulate cortex intermixes a precise spatial map with a cognitive map of the task, and spontaneously recalls multimodal information about unrealized choice outcomes during pauses in behavior after reinforcements.
An analysis of review, promotion and tenure documents from 129 US and Canadian universities suggests institutions could better fulfill their public missions by changing how they incentivize the public dimensions of faculty work.
