Characterization of intracortical synaptic connections in the mouse anterior cingulate cortex using dual patch clamp recording [PDF]

open access: yesMolecular Brain, 2009
Summary The anterior cingulate cortex (ACC) is involved in sensory, cognitive, and executive functions. Studies of synaptic transmission and plasticity in the ACC provide an understanding of basic cellular and molecular mechanisms for brain functions ...

Why Neurons Have Thousands of Synapses, A Theory of Sequence Memory in Neocortex [PDF]

open access: yesFrontiers in Neural Circuits, 2016
Pyramidal neurons represent the majority of excitatory neurons in the neocortex. Each pyramidal neuron receives input from thousands of excitatory synapses that are segregated onto dendritic branches.

Thalamocortical feedback selectively controls pyramidal neuron excitability [PDF]

open access: yesNature Communications
The apical dendrites of layer (L) 2/3 pyramidal neurons in the mouse somatosensory cortex integrate synaptic input from long-range projections. Among those, inputs from the higher-order thalamic posteromedial nucleus may facilitate sensory-evoked ...

Action potential modulation in CA1 pyramidal neuron axons facilitates OLM interneuron activation in recurrent inhibitory microcircuits of rat hippocampus. [PDF]

open access: yesPLoS ONE, 2014
Oriens-lacunosum moleculare (O-LM) interneurons in the CA1 region of the hippocampus play a key role in feedback inhibition and in the control of network activity. However, how these cells are efficiently activated in the network remains unclear.

Altered synaptic plasticity at hippocampal CA1–CA3 synapses in Alzheimer's disease: integration of amyloid precursor protein intracellular domain and amyloid beta effects into computational models

open access: yesFrontiers in Computational Neuroscience, 2023
Alzheimer's disease (AD) is a progressive memory loss and cognitive dysfunction brain disorder brought on by the dysfunctional amyloid precursor protein (APP) processing and clearance of APP peptides.

Multiple synaptic connections into a single cortical pyramidal cell or interneuron in the anterior cingulate cortex of adult mice

open access: yesMolecular Brain, 2021
The ACC is an important brain area for the processing of pain-related information. Studies of synaptic connections within the ACC provide an understanding of basic cellular and molecular mechanisms for brain functions such as pain, emotion and related ...

Analysis of Mouse Brain Sections by Live-cell Time-lapse Confocal Microscopy

open access: yesBio-Protocol, 2023
The developing cerebral cortex of mammals is generated from nascent pyramidal neurons, which radially migrate from their birthplace in the ventral part of the neural tube to the cortical surface.

Stereology neuron counts correlate with deep learning estimates in the human hippocampal subregions

open access: yesScientific Reports, 2023
Hippocampal subregions differ in specialization and vulnerability to cell death. Neuron death and hippocampal atrophy have been a marker for the progression of Alzheimer’s disease.

Occasional essay: upper motor neuron syndrome in amyotrophic lateral sclerosis [PDF]

open access: yes, 2020
The diagnosis of amyotrophic lateral sclerosis (ALS) requires recognition of both lower (LMN) and upper motor neuron (UMN) dysfunction.1 However, classical UMN signs are frequently difficult to identify in ALS.2 LMN involvement is sensitively detected ...
