We examined how hippocamal CA1 neurons process complex time-varying inputs that dendrites are likely to receive in vivo. We propose a functional model of the dendrite-to-soma input/output relationship that combines temporal integration and static-gain control mechanisms. Using simultaneous dual whole-cell recordings, we injected fifty seconds of subthreshold and suprathreshold zero-mean white-n...

Structure-controlled Pt-based catalysts have been known to exhibit improved electrocatalytic activities due to particularly modulated surface structures favorable for alcohol electrooxidation. We report PtNi alloy dendrite structure for formic acid electrooxidation prepared by a thermal decomposition method. The Pt-Ni nanodendrites display 3-dimentional nanostructure and homogeneous alloy forma...

Recently in proving certain existence theorems for non-alternating and for interior transformations of a continuum onto a simple arc it was observed that when a transformation of one of these types was set up, usually it satisfied in large measure conditions which brought it also under transformations of the other type. This suggests the existence of common ground shared by these sorts of trans...

The formation of lithium dendrites in solid-state lithium-ion batteries leads to short-circuiting and cell failure. One proposed mechanism for dendrite growth is the direct reduction ions, due residual electronic conductivity nominally insulating solid electrolyte. This article presents a fully first-principles scheme modeling materials, such as electrolytes, function synthesis protocol, applie...

conclusions the findings of this study indicate that the frequency of disfluencies was increased in difficult syllable structures in comparison to simple syllable structures. according to the results, it seems that certain linguistic features, such as syllable structure can affect speech-motor output in people who stutter through affecting phonological encoding. background stuttering is one of ...

objective: to compare the emotional structure and coping strategies in patients with psychogenic non epileptic seizures, epilepsy and control group. methods: among patients with complaining of epilepsy attacks that referred to clinic of imam reza (peace be upon him) in shiraz, 30 patients with psychogenic non epileptic seizures and 30 patients with epilepsy were selected .a total of 30 patients...

Dendrites exhibit enormous diversity in form and can differ in size by several orders of magnitude even in a single animal. However, whether neurons with large dendrite arbors have specialized mechanisms to support their growth demands is unknown. To address this question, we conducted a genetic screen for mutations that differentially affected growth in neurons with different-sized dendrite ar...

Experimental results obtained as part of a series of experiments on dendritic growth in microgravity, the isothermal dendritic growth experiment (IDGE), indicate that Ivantsov's transport solution to the dendrite problem is valid to "rst order. The data reveal a PeH clet (Pe) number vs. supercooling relationship that is both systematically lower than expected, and exhibits larger scatter than i...
