Mapping Large-scale Spatiotemporal Dynamics of Synaptic Plasticity and LTP for Memory Encoding in the Hippocampal Network

This paper introduces EVOX, a platform for mapping synaptic plasticity and LTP in hippocampal networks, showing high-frequency stimulation induces network-wide LTP.

Local contribution to the somatosensory evoked potentials in rat's thalamus

The paper shows that local thalamic LFP can be reliably recovered using kCSD, even without concurrent cortical recordings, by removing a negative component from cortex.

kCSD-python, reliable current source density estimation with quality control

kCSD-python provides a Python package for reliable current source density estimation with quality control techniques and diagnostic tools.

What we can and what we cannot see with extracellular multielectrodes

The paper analyzes what information about brain current sources can be recovered or remains unobservable using extracellular multielectrode recordings, across different experimental setups.

Network and synaptic mechanisms underlying high frequency oscillations in the rat and cat olfactory bulb under ketamine-xylazine anesthesia.

This study identifies ketamine-xylazine-induced high frequency oscillations (HFO) in the olfactory bulb of rats and cats, showing they depend on nasal airflow and local dendrodendritic interactions, not gap junctions or the piriform cortex.

Spreading depressions and periinfarct spreading depolarizations in the context of cortical plasticity

This study investigates whether spreading depolarizations (SDs) and periinfarct depolarizations (PiDs) impair cortical experience-dependent plasticity (ExDP) similarly to stroke, finding no direct causal link between SDs/PiDs and metaplasticity changes.

Nasal respiration is necessary for the emergence of ketamine-induced high frequency network oscillations and behavioral hyperactivity in freely moving rats.

This study shows that nasal respiration is required for ketamine-induced high-frequency oscillations and hyperactivity in rats, with HFOs coupled to theta-frequency sniffing.
