Targeting Ion Channels to Distal Dendrites
… boutons transmit synaptic signals, and dendrites receive and integrate synaptic information. These functional differences are achieved by localizing different complements of proteins to these compartments; axons contain a high density of voltage-gated channels, presynaptic boutons house …

Dendrites or lambda-dendroids as generalized inverse limits
<p>"This research centers on the study of generalized inverse limits. We show that all members of an infinite family of inverse limit spaces are homeomorphics to one particularly complicated inverse limit space known as "The Monster". Further, properties of factor spaces and graphs of bonding …

Regulation of Microtubules by Patronin within Drosophila Dendrites
… all cells, comprising of a cell body, axon and dendrites. The development and function of each compartment relies heavily on the cytoskeleton, a major component of which are microtubules, which are required for intracellular transport, as well as establishing neuronal morphology. In this thesis, …

Optical imaging of dendritic spikes in apical oblique dendrites of layer 5 pyramidal neurons
Dendrites have active properties capable of generating dendritic spikes that could boost the impact of distal synaptic inputs. The strong passive filtering of the membrane and generation of local dendritic spikes enable different dendritic regions to function as independent computational …

Regulation of Polarized Protein Transport to Axons, Dendrites, and Sensory Cilia in Caeborhabditis Elegans Neurons
… specialized domains, an axon and one or more dendrites. The molecular dissimilarities between these domains are critical for neuronal function, and are a result of asymmetric trafficking of a large number of cellular components including ion channels, neurotransmitter receptors, synaptic …

Feedback control of analog neurons and shunting inhibition in dendrites for bio-inspired neuromorphic systems.
… investigates the potential of using analog dendrites in motion vision applications. Inspired by recent findings in Drosophila T4 neurons, an analog circuit using shunting inhibition is shown to enable high-level computation like coincidence detection and direction selectivity. This approach …

Bioprobes and Genetics Reveal the Signal Integration That Initiates Dendrites in a Neuron in Vivo
Precise positioning of axons and dendrites in the CNS holds the key to establishing neural networks. To achieve this, each subcellular compartment in differentiating neurons must translate cues from surrounding tissues into cytoskeletal rearrangements by orchestrating intrinsic signaling molecules. …

Calcium dynamics in dendrites and spines of spiny neurons in the somatosensory ‘barrel’ cortex of the rat
… technique to study the Ca2+ dynamics in dendrites and spines of spiny neurons of layer 4 of the somatosensory cortex in acute thalamocortical brain slices of young (P13-P15) rats. Back-propagating action potentials (bAPs) resulted in a transient rise in Ca2+ in all dendrites and spines …

A Three-Molecule Model of Structural Plasticity: the Role of the Rho family GTPases in Local Biochemical Computation in Dendrites
… small protrusions emanating from neuronal dendrites that constitute the majority of recipient sites of excitatory neuronal connections. The unique, mushroom-like morphology of these tiny structures has earned them considerable attention, with even the earliest observers suggesting that …

EXERCISE IS NEUROPROTECTIVE TO MOTONEURON DENDRITES FOLLOWING PARTIAL MOTONEURON DEPLETION VIA A MECHANISM DEPENDENT ON ANDROGEN RECEPTORS AT THE TARGET MUSCLE
Motoneuron loss is a severe medical problem that can result in loss of motor control and eventually death. It has been previously demonstrated that partial motoneuron loss can result in dendritic atrophy and functional deficits in nearby surviving motoneurons, and that treatment with testosterone …

Neuronal filopodia borne along tips and shafts of dendrites comprise two distinct populations as evidenced by differences in structure and dynamics
Ever since their discovery in 1880 by Ramon y Cajal, dendritic spines have evoked considerable interest in the field of cellular and molecular neuroscience. Subsequent studies into their morphogenesis, and into synaptogenesis, brought into the spotlight their putative precursors – the dendritic …

Defect and deformation studies in transition metal trialuminide compounds
… Al-25at.%Ti alloy powder consisted of primary dendrites of the $\rm Al\sb3Ti$ phase (DO$\sb{22}$ structure) and $\alpha$-aluminum. The as-atomized Al-25at.%V alloy exhibited a microstructure composed of primary $\rm Al\sb8V\sb5$ dendrites with interdendritic $\rm Al\sb3V$ (DO$\sb{22}$) and …

Mechanisms of dendritic peptide release
… that regulates this differential release is that dendrites utilise different vesicle pools compared to those found in terminals. Little is known for the function of neuronal dendrites, especially the mechanism for peptide release. One theory is that vesicles stored in dendrites are non-released …

Water modeling the solid oxide membrane electrolysis with rotating cathode process
… fluid will create a fully-dense ingot instead of dendrites, because dendrites are undesirable. Using a camera, a plane of light and titanium dioxide particles, videos and pictures of the water were taken and analyzed to find how to create a large amount of shear between the ingot and the fluid. …

Role of the immunoglobulin superfamily member Basigin in sensory neuron dendrite morphogenesis in Drosophila

Stress-induced remodeling of the caenorhabditis elegans dauer
