Intrinsic excitability of CA1 pyramidal neurones from the rat dorsal and ventral hippocampus.
The hippocampus has a central role in learning and memory. Although once considered a relatively homogenous structure along the longitudinal axis, it has become clear that the rodent hippocampus can be anatomically and functionally divided into a dorsal component generally associated with spatial navigation, and a ventral component primarily associated with non-spatial functions that involve an...
متن کاملProperties of single voltage-dependent K+ channels in dendrites of CA1 pyramidal neurones of rat hippocampus.
Voltage-dependent K(+) channels in the apical dendrites of CA1 pyramidal neurones play important roles in regulating dendritic excitability, synaptic integration, and synaptic plasticity. Using cell-attached, voltage-clamp recordings, we found a large variability in the waveforms of macroscopic K(+) currents in the dendrites. With single-channel analysis, however, we were able to identify four ...
متن کاملSubthreshold voltage noise of rat neocortical pyramidal neurones.
Neurones are noisy elements. Noise arises from both intrinsic and extrinsic sources, and manifests itself as fluctuations in the membrane potential. These fluctuations limit the accuracy of a neurone's output but have also been suggested to play a computational role. We present a detailed study of the amplitude and spectrum of voltage noise recorded at the soma of layer IV-V pyramidal neurones ...
متن کاملRapid Golgi Technique for Staining Pyramidal Neurons in Rat Hippocampus
The Golgi-Cox is a gold standard technique to stain the neurons. However the major limitations of the study are that it is time taking and inconsistent. In this paper we describe a modification of the Golgi–Cox method, in which the tissue blocks were immersed in rapid Golgi solution and silver nitrate for staining of neurons in rat brain. The method is simple, reproducible, rapid, inexpensive a...
متن کاملMorphology of CA3 non-pyramidal cells in the developing rat hippocampus.
Although several investigations have shown that the local GABAergic circuit in the rat hippocampus is functional very early in development, this result has not been yet completed by the investigation of the full dendritic and axonal arborization of the neonatal interneurones. In the present study, intracellular injection of biocytin was used to assess the branching pattern of interneurones in t...
