An integrated, temporal study of the behavioural, electrophysiological and neuropathological consequences of murine prion disease

open access: yesNeurobiology of Disease, 2006
We have conducted an integrated study of ME7 prion disease by examining the electrophysiological and neuropathological features of hippocampal slices from behaviourally characterised C57Bl/6J mice 12, 14, 16, 18, 20 and 24 weeks after intracerebral micro-

Local circuit allowing hypothalamic control of hippocampal area CA2 activity and consequences for CA1

open access: yeseLife, 2021
The hippocampus is critical for memory formation. The hypothalamic supramammillary nucleus (SuM) sends long-range projections to hippocampal area CA2. While the SuM-CA2 connection is critical for social memory, how this input acts on the local circuit is

The epitranscriptome and synaptic plasticity

open access: yesCurrent Opinion in Neurobiology, 2019
RNA modifications, collectively referred to as 'the epitranscriptome,' have recently emerged as a pervasive feature of cellular mRNAs which have diverse impacts on gene expression. In the last several years, technological advances improving our ability to identify mRNA modifications, coupled with the discovery of proteins that add and remove these ...

Synaptic plasticity in schizophrenia pathophysiology

open access: yesIBRO Neuroscience Reports, 2023
Schizophrenia is a severe neuropsychiatric syndrome with psychotic behavioral abnormalities and marked cognitive deficits. It is widely accepted that genetic and environmental factors contribute to the onset of schizophrenia. However, the etiology and pathology of the disease remain largely unexplored.

Synaptic plasticity through activation of GluA3-containing AMPA-receptors

open access: yeseLife, 2017
Excitatory synaptic transmission is mediated by AMPA-type glutamate receptors (AMPARs). In CA1 pyramidal neurons of the hippocampus two types of AMPARs predominate: those that contain subunits GluA1 and GluA2 (GluA1/2), and those that contain GluA2 and ...

Interneuron-specific plasticity at parvalbumin and somatostatin inhibitory synapses onto CA1 pyramidal neurons shapes hippocampal output

open access: yesNature Communications, 2020
Inhibitory interneuron subtypes differentially control place cell representations in CA1. Here, the authors show that parvalbumin and somatostatin interneuron synapses onto CA1 pyramidal neurons exhibit distinct plasticity mechanisms and incorporating ...

Linking spontaneous and stimulated spine dynamics

open access: yesCommunications Biology, 2023
Our brains continuously acquire and store memories through synaptic plasticity. However, spontaneous synaptic changes can also occur and pose a challenge for maintaining stable memories.

Neurodegenerative Disease: What Potential Therapeutic Role of Acid-Sensing Ion Channels?

open access: yesFrontiers in Cellular Neuroscience, 2021
Acidic pH shift occurs in many physiological neuronal activities such as synaptic transmission and synaptic plasticity but also represents a characteristic feature of many pathological conditions including inflammation and ischemia.

Endoplasmic reticulum visits highly active spines and prevents runaway potentiation of synapses

open access: yesNature Communications, 2020
In hippocampal pyramidal cells, a subset of dendritic spines contain endoplasmic reticulum (ER). Here, the authors show that ER enters dendritic spines in a non-random manner, during high synaptic activity with the function of limiting synaptic strength.

Synaptic plasticity and phosphorylation [PDF]

open access: yesPharmacology & Therapeutics, 2006
A number of neuronal functions, including synaptic plasticity, depend on proper regulation of synaptic proteins, many of which can be rapidly regulated by phosphorylation. Neuronal activity controls the function of these synaptic proteins by exquisitely regulating the balance of various protein kinase and protein phosphatase activity.
