Article Synopsis
- Grid cells in the brain, which help with spatial navigation, typically show a firing pattern in triangular grids, but direct recordings from humans are rare.
- Previous fMRI studies have tried to measure grid cell activity indirectly by observing changes in brain activity related to a person's movement direction, but the cause of these changes is still debated.
- The current research suggests that orientation related to the grid's axes may explain observed patterns better than other proposed mechanisms, highlighting the need for further studies on human grid cells and their properties.
Remembering the temporal order of a sequence of events is a task easily performed by humans in everyday life, but the underlying neuronal mechanisms are unclear. This problem is particularly intriguing as human behavior often proceeds on a time scale of seconds, which is in stark contrast to the much faster millisecond time-scale of neuronal processing in our brains. One long-held hypothesis in sequence learning suggests that a particular temporal fine-structure of neuronal activity - termed 'phase precession' - enables the compression of slow behavioral sequences down to the fast time scale of the induction of synaptic plasticity.
