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

open access: yes, 2015
Neocortical neurons have thousands of excitatory synapses. It is a mystery how neurons integrate the input from so many synapses and what kind of large-scale network behavior this enables.

Step by Step Golgi-Cox Staining for Cryosection

open access: yesFrontiers in Neuroanatomy, 2019
Golgi staining, though invented hundreds of years ago, is still a reliable method to study the cytoarchitecture of the brain. Almost all published Golgi staining protocols and methods were used for microtome, and rarely applied in cryosection, which ...

A multi-protein receptor-ligand complex underlies combinatorial dendrite guidance choices in C. elegans. [PDF]

open access: yes, 2016
Ligand receptor interactions instruct axon guidance during development. How dendrites are guided to specific targets is less understood. The C. elegans PVD sensory neuron innervates muscle-skin interface with its elaborate dendritic branches.

Autologous nerve graft repair of different degrees of sciatic nerve defect: stress and displacement at the anastomosis in a three-dimensional fnite element simulation model

open access: yesNeural Regeneration Research, 2015
In the repair of peripheral nerve injury using autologous or synthetic nerve grafting, the magnitude of tensile forces at the anastomosis affects its response to physiological stress and the ultimate success of the treatment.

Directing lateral growth of lithium dendrites in micro-compartmented anode arrays for safe lithium metal batteries

open access: yesNature Communications, 2018
Uncontrolled growth of lithium dendrites during cycling has remained a challenging issue for lithium metal batteries. Thus far, various approaches have been proposed to delay or suppress dendrite growth, yet little attention has been paid to the ...

Synaptogenic activity of the axon guidance molecule Robo2 underlies hippocampal circuit function

open access: yesCell Reports, 2021
Summary: Synaptic connectivity within adult circuits exhibits a remarkable degree of cellular and subcellular specificity. We report that the axon guidance receptor Robo2 plays a role in establishing synaptic specificity in hippocampal CA1.

The role of ongoing dendritic oscillations in single-neuron dynamics [PDF]

open access: yes, 2009
The dendritic tree contributes significantly to the elementary computations a neuron performs while converting its synaptic inputs into action potential output.

A dendrite is a dendrite is a dendrite? Dendritic signal integration beyond the “antenna” model

open access: yesPflügers Archiv - European Journal of Physiology
AbstractNeurons in central nervous systems receive multiple synaptic inputs and transform them into a largely standardized output to their target cells—the action potential. A simplified model posits that synaptic signals are integrated by linear summation and passive propagation towards the axon initial ...

Ordered arrangement of dendrites within a C. elegans sensory nerve bundle

open access: yeseLife, 2018
Biological systems are organized into well-ordered structures and can evolve new patterns when perturbed. To identify principles underlying biological order, we turned to C. elegans for its simple anatomy and powerful genetics.

Widespread phosphorous excess in olivine, rapid crystal growth, and implications for magma dynamics

open access: yesVolcanica, 2022
Trace element zoning is often used to unravel the crystallization history of phenocrysts in magmatic systems, but interpretation requires quantifying the relative importance of equilibrium versus disequilibrium.
