Calcineurin signaling mediates activity-dependent relocation of the axon initial segment

MD Evans, RP Sammons, S Lebron… - Journal of …, 2013 - Soc Neuroscience
The axon initial segment (AIS) is a specialized neuronal subcompartment located at the
beginning of the axon that is crucially involved in both the generation of action potentials and the …

[PDF][PDF] Subnetwork-specific homeostatic plasticity in mouse visual cortex in vivo

SJ Barnes, RP Sammons, RI Jacobsen, J Mackie… - Neuron, 2015 - cell.com
Homeostatic regulation has been shown to restore cortical activity in vivo following sensory
deprivation, but it is unclear whether this recovery is uniform across all cells or specific to a …

Human cerebrospinal fluid monoclonal LGI1 autoantibodies increase neuronal excitability

…, Y Fukata, D Parthier, RP Sammons… - Annals of …, 2020 - Wiley Online Library
Objective Leucine‐rich glioma‐inactivated 1 (LGI1) encephalitis is the second most common
antibody‐mediated encephalopathy, but insight into the intrathecal B‐cell autoimmune …

[PDF][PDF] Hippocampal GABAergic interneurons and memory

A Tzilivaki, JJ Tukker, N Maier, P Poirazi, RP Sammons… - Neuron, 2023 - cell.com
One of the most captivating questions in neuroscience revolves around the brain's ability to
efficiently and durably capture and store information. It must process continuous input from …

[PDF][PDF] Estrus-cycle regulation of cortical inhibition

AM Clemens, C Lenschow, P Beed, L Li, R Sammons… - Current Biology, 2019 - cell.com
Female mammals experience cyclical changes in sexual receptivity known as the estrus
cycle. Little is known about how estrus affects the cortex, although alterations in sensation, …

[HTML][HTML] Spermidine protects from age-related synaptic alterations at hippocampal mossy fiber-CA3 synapses

…, FE Müller, L Moreno-Velasquez, RP Sammons… - Scientific Reports, 2019 - nature.com
Aging is associated with functional alterations of synapses thought to contribute to age-dependent
memory impairment (AMI). While therapeutic avenues to protect from AMI are largely …

Cannabinoid type 2 receptors mediate a cell type-specific self-inhibition in cortical neurons

A Stumpf, D Parthier, RP Sammons, AV Stempel… - …, 2018 - Elsevier
Endogenous cannabinoids are diffusible lipid ligands of the main cannabinoid receptors
type 1 and 2 (CB 1 R and CB 2 R). In the central nervous system endocannabinoids are …

Adult plasticity and cortical reorganization after peripheral lesions

RP Sammons, T Keck - Current Opinion in Neurobiology, 2015 - Elsevier
Highlights • Cortical remapping of receptive fields occurs following peripheral lesions in adult.
• Cortical reorganization has a rapid onset and continues for several weeks to months. • …

Structure and function of the hippocampal CA3 module

RP Sammons, M Vezir… - Proceedings of the …, 2024 - National Acad Sciences
The hippocampal formation is crucial for learning and memory, with submodule CA3
thought to be the substrate of pattern completion. However, the underlying synaptic and …

[PDF][PDF] Size-dependent axonal bouton dynamics following visual deprivation in vivo

RP Sammons, C Clopath, SJ Barnes - Cell reports, 2018 - cell.com
Persistent synapses are thought to underpin the storage of sensory experience, yet little is
known about their structural plasticity in vivo. We investigated how persistent presynaptic …
