RealtimeDecoder: A fast software module for online clusterless decoding

RealtimeDecoder is a Python-based system for real-time clusterless decoding of neural data with low latency and no spike sorting, demonstrated in rodent hippocampus recordings.

Closed-loop modulation of remote hippocampal representations with neurofeedback

This study shows rats can learn to generate specific remote hippocampal representations through neurofeedback without external cues or behavioral reports.

Spatial preferences account for inter-animal variability during the continual learning of a dynamic cognitive task

The paper identifies spatial preferences in rats during a spatial alternation task, showing how these preferences contribute to inter-animal variability in learning.

Hippocampal replay reflects specific past experiences rather than a plan for subsequent choice

This study investigates hippocampal replay during memory-guided behavior and finds that replay content reflects past experiences rather than future choices.

Constant sub-second cycling between representations of possible futures in the hippocampus

The paper shows hippocampal neurons cycle between representations of alternative future locations at 8 Hz, driven by theta rhythm, and also represent heading direction alternatives.

A microfabricated, 3D-sharpened silicon shuttle for insertion of flexible electrode arrays through dura mater into brain

This paper introduces a 3D-sharpened silicon shuttle for inserting flexible electrode arrays through dura mater into rat brains, enabling less damaging and faster implantation for chronic recordings.

High-density, long-lasting, and multi-region electrophysiological recordings using polymer electrode arrays

This paper introduces a high-density, long-term electrophysiological recording system for freely behaving rats, enabling multi-region neural activity monitoring over extended periods.

Marked point process filter for clusterless and adaptive encoding-decoding of multiunit activity

The paper introduces a Bayesian encoding model for real-time adaptation of neural activity decoding in rats during maze exploration.

Specific hippocampal representations are linked to generalized cortical representations in memory.

The paper shows that specific hippocampal place representations are reactivated with generalized prefrontal cortical task representations during memory reactivation in a foraging task.
