Neuronal dendrites are central to memory & learning. New #microscopy technique shows individual #dendrites have distinct distributions of spine types, hinting at individual roles. Learn more in #Neurophotonics: www.spiedigitallibra... #Neuroscience #NeuroImaging

A previous study in #plosbiology found that Wnt receptors are housed in early endosomes and required for dendritic #microtubule nucleation. This Update Article shows that microtubule dynamics in #dendrites can be influenced non-autonomously by surrounding epithelial cells plos.io/3DK0M0J
`In this work, we investigated the #dendrites of layer 2 and 3 (L2/3) pyramidal #neurons of the human cerebral cortex ex vivo. In these neurons, we discovered a class of #calcium-mediated dendritic action potentials (dCaAPs) whose waveform and effects on #neuronal output have not been previously described. In contrast to typical all-or-none action potentials, dCaAPs were graded; their amplitudes were maximal for threshold-level stimuli but dampened for stronger stimuli`
Summer vibes! Here researchers have captured dendrite generated on a zinc surface, and added their own seaside-themed flourish.

Dendritic computation,
synaptic plasticity & molecular mechanisms
#Nerve #cells (#neurons ) are amongst the most complex cell types in our body. They achieve this complexity during development by extending ramified branches called #dendrites and #axons and establishing thousands of synapses to form intricate networks.

`In contrast to typical all-or-none action potentials, dCaAPs were graded; their amplitudes were maximal for threshold-level stimuli but dampened for stronger stimuli. These dCaAPs enabled the #dendrites of individual human neocortical pyramidal #neurons to classify linearly nonseparable inputs—a computation conventionally thought to require multilayered #networks.`

"Here we combine cable and renewal theory to describe how input fluctuations shape the response of neuronal ensembles with active #dendrites. We found that dendritic input readily and potently controls interspike interval dispersion. This phenomenon can be understood by considering that #neurons display three fundamental operating regimes: one mean-driven regime and two fluctuation-driven regimes."
Dendrite formation is the bane of lithium batteries.
"In the new research, Li and his team stop #dendrites from forming by using micron-sized silicon particles in the anode to constrict the lithiation reaction and facilitate homogeneous plating of a thick layer of #lithium metal."

"Knock out of Noelins1-3 profoundly reduced AMPARs in synapses onto excitatory and inhibitory (inter)neurons, decreased their density and clustering in #dendrites, and abolished activity-dependent #synaptic plasticity. Our results uncover an endogenous mechanism for #extracellular anchoring of AMPARs and establish Noelin-organized networks as versatile determinants of constitutive and context-dependent #neurotransmission."
"An international research team involving scientists has described the process of growing three-dimensional manganese dendrites. The researchers found that it occurs through accretion of manganese oxide nanoparticles. Understanding the dynamics of the growth of three-dimensional mineral dendrites is important for various fields of science - physics, geology, material sciences and even the study of extraterrestrial environments".
