The paper identifies time cells in the human brain that support working memory by forming sequences encoding time and memory content during WM maintenance.

This study investigates how hippocampal sequences represent working memory and implicit timing in a rodent task where odor identity predicts delay duration.

This study shows that behavioral timescale synaptic plasticity (BTSP) in the hippocampus generates non-spatial representations during learning, with MEC and LEC playing distinct roles in driving BTSP and odor-specific responses.

This paper introduces positively tuned GEVIs that enhance spike detection in vivo with standard imaging systems, offering higher temporal resolution than calcium indicators.

The paper uses voltage imaging to show that hippocampal interneurons modulate memory-encoding pyramidal sequences through inhibition, enhancing signal-to-noise ratios during odor-cued working memory tasks.

This study investigates whether working memory and timing share neural mechanisms by using psychophysical tasks and RNN simulations, finding that cue-specific neural sequences multiplex both functions.

This study investigates the effects of CNTNAP2 loss-of-function mutations in mice, finding reduced synaptic connectivity and altered oscillatory dynamics in the prefrontal cortex associated with autism-like behaviors.

CaImAn, an open-source library, automates motion correction, source extraction, deconvolution and cross-session registration for calcium imaging, detecting neurons near human level (F1 0.75 batch, 0.76 online).

The paper shows that hippocampal CA1 neurons form stable odor representations and dynamic time representations during an olfactory working memory task.

This study investigates spatial coding and neural synchronization in epilepsy using in vivo calcium imaging and network modeling, finding impaired spatial processing and desynchronized firing in epileptic mice.
