Effetto della separazione materna sulla plasticità dei neuroni nell’ippocampo delle mamme e della prole
… and we analized density and morphology of dendritic spines and arborization of the dendritic tree in granule cells of hippocampus. Another goal of our study is to verify on the offspring, if stress induced by insufficient maternal care in the first 15 days of life increases the …

Strength and dendritic organization of thalamocortical synapses onto excitatory layer 4 neurons
… map the locations of synapses across an entire dendritic tree. This demonstrated that TC synapses are slightly more proximal to the soma than CC synapses, but detailed compartmental modeling predicted that dendritic filtering does not appreciably favor one synaptic class over another. …

Low-rank graphical models and Bayesian inference in the statistical analysis of noisy neural data
… application to the locating of synapses in a dendritic tree. We develop a compartmentalized model of the dendritic tree. Building on previous work that applied and generalized ideas of least angle regression to obtain a fast Bayesian solution to the resulting estimation problem, we describe …

New biophysical methods for the characterization of signal transfer in neurons
Many neurons have extensive dendritic trees, and therefore somatic voltage clamp of dendritic synapses is often associated with substantial distortion and attenuation of the synaptic currents. A new method is presented which permits faithful extraction of the decay time constant of the synaptic …

Motor and Cerebellar Effects in Rats Exposed to PCBs and Methylmercury During Early Development
… brains. There were no significant changes in dendritic tree branching area, primary dendrite length, or PC structural abnormalities, which included ectopic PCs. However, exposed male rats did show a marginally significant increase in PC height, suggesting a subtle thyromimetic effect in the …

THE CRAYFISH VISUAL SYSTEM: INTRACELLULAR STUDIES AND MORPHOLOGIES OF IDENTIFIED INTERNEURONS
… Following identification of each cell, the dendritic morphology was observed with lucifer yellow iontophoresis and subsequent fluorescence microscopy. An individual SF possesses a dendritic arborization restricted to that portion of the Medulla corresponding to its corneal receptive field. …

The feeding ecology of deposit-feeding holothurians
… at the subclass or order level (Pawson, 1966). Dendritic, tree-like tentacles are used by suspension-feeding holothurians to filter particulate matter from the water; they are found in dendrochirotids as described by McKenzie (1987). Pinnate tentacles are very fine and feather-like and occur in …

Investigation and Modelling of Fetal Sheep Maturation
… and the rate constants of the near- and far-dendritic tree. In the end, I selected the classic and simpler Waikato slow-soma mean-field model to use for my immature cortex simulations. Model parameters are customised based on the physiology of the immature cortex, including GABA (an …

PIP2 Modulation of Afterhyperpolarizations in Magnocellular Supraoptic Neurons
… between AHP amplitude, [Ca2+]i, and dendritic size. There is a moderate relationship between AHP amplitude and dendritic length in both OT and VP neurons, suggesting that a considerable portion of the AHP conductance could occur in the dendritic tree of these neurons. These studies …

Elucidating the reversibility of ataxia
… Purkinje cell firing frequency followed by dendritic tree degeneration and cell death. The aims of this study were to evaluate progression of Purkinje cell degeneration following loss of b-III spectrin function and determine whether the reintroduction of C-terminus (C-trm) of b-III spectrin …

Regulating transcript fate through RNA elements in the 3' untranslated region
… in rapid response to changing conditions such as dendritic tree formation, ischemia, heat shock, and immune response. Such regulation also performs a vital role in development of embryos, oocytes, and spermatozoa. Spermatogenesis is the process of the creation of spermatozoa from primordial germ …
