Hyperexcitable Parvalbumin Interneurons Render Hippocampal Circuitry Vulnerable to Amyloid Beta

open access: yesiScience, 2020
Summary: Parvalbumin (PV) interneuron dysfunction is associated with various brain disorders, including Alzheimer disease (AD). Here, we asked whether early PV neuron hyperexcitability primes the hippocampus for amyloid beta-induced functional impairment.

Weak electric fields promote resonance in neuronal spiking activity: Analytical results from two-compartment cell and network models. [PDF]

open access: yesPLoS Computational Biology, 2019
Transcranial brain stimulation and evidence of ephaptic coupling have sparked strong interests in understanding the effects of weak electric fields on the dynamics of neuronal populations. While their influence on the subthreshold membrane voltage can be

Gephyrin-Lacking PV Synapses on Neocortical Pyramidal Neurons [PDF]

open access: yesInternational Journal of Molecular Sciences, 2021
Gephyrin has long been thought of as a master regulator for inhibitory synapses, acting as a scaffold to organize γ-aminobutyric acid type A receptors (GABAARs) at the post-synaptic density. Accordingly, gephyrin immunostaining has been used as an indicator of inhibitory synapses; despite this, the pan-synaptic localization of gephyrin to specific ...

PyramidalExplorer: A new interactive tool to explore morpho-functional relations of pyramidal neurons

open access: yesFrontiers in Neuroanatomy, 2016
This work presents PyramidalExplorer, a new tool to interactively explore and reveal the detailed organization of the microanatomy of pyramidal neurons with functionally related models. It consists of a set of functionalities that allow possible regional

Differences in Noradrenaline Receptor Expression Across Different Neuronal Subtypes in Macaque Frontal Eye Field

open access: yesFrontiers in Neuroanatomy, 2020
Cognitive functions such as attention and working memory are modulated by noradrenaline receptors in the prefrontal cortex (PFC). The frontal eye field (FEF) has been shown to play an important role in visual spatial attention.

The enigmatic function of chandelier cells

open access: yesFrontiers in Neuroscience, 2010
Chandelier (or axo-axonic) cells are one of the most distinctive GABAergic interneurons in the brain. Their exquisite target specificity for the axon initial segment of pyramidal neurons, together with their GABAergic nature, long suggested the ...

Size of hippocampal pyramidal neurons in schizophrenia [PDF]

open access: yesBritish Journal of Psychiatry, 2003
BackgroundMeta-analyses of hippocampal size have indicated that this structure is smaller in schizophrenia. This could reflect a reduction in the size of constituent neurons or a reduced number of neurons.AimsTo measure the size of hippocampal pyramidal neurons in the brains of people with and without schizophrenia.MethodPyramidal neuron size in ...

A realistic computational model for the formation of a Place Cell

open access: yesScientific Reports, 2023
Hippocampal Place Cells (PCs) are pyramidal neurons showing spatially localized firing when an animal gets into a specific area within an environment. Because of their obvious and clear relation with specific cognitive functions, Place Cells operations ...

The Spatial Structure of Stimuli Shapes the Timescale of Correlations in Population Spiking Activity [PDF]

open access: yes, 2012
Throughout the central nervous system, the timescale over which pairs of neural spike trains are correlated is shaped by stimulus structure and behavioral context.
