In the visual system retinal space is compressed such that acuity decreases further from the
fovea. Different forms of memory may rely on a compressed representation of time …

Highlights•Brain state changes slowly providing a temporal context for memories.•Models
predict recovery of a prior state of context causes episodic memory.•A recent theory …

Episodic memory is believed to be intimately related to our experience of the passage of
time. Indeed, neurons in the hippocampus and other brain regions critical to episodic …

We remember our lives as sequences of events, but it is unclear how these memories are
controlled during retrieval. In rats, the medial prefrontal cortex (mPFC) is positioned to …

Abstract The Weber-Fechner law proposes that our perceived sensory input increases with
physical input on a logarithmic scale. Hippocampal 'time cells' carry a record of recent …

Reinforcement learning is a powerful approach to learn behaviour through interactions with
an environment. However, behaviours are usually learned in a purely reactive fashion …

Adaptive memory requires the organism to form associations that bridge between events
separated in time. Many studies show interactions between hippocampus (HPC) and …

Recent theoretical and experimental results suggest that the dopamine system implements
distributional temporal difference backups, allowing learning of the entire distributions of the …

Memory for the past makes use of a record of what happened when---a function over past
time. Time cells in the hippocampus and temporal context cells in the entorhinal cortex both …

A growing body of evidence suggests that short-term memory does not only store the identity
of recently experienced stimuli, but also information about when they were presented. This …
