Uncoupling of CA3 pyramidal neurons by propionate
Brain Research, 1985The influence of cytoplasmic acidification on dye-coupling between CA3 pyramidal neurons was examined by Lucifer yellow injections in guinea pig hippocampal brain slices. Neurons were believed to be acidified by exposure to 100 mM propionate. Dye-coupling was reduced significantly to 6% (n = 35) in propionate versus 28% (n = 39) in control solution (P ...

Do Neocortical Pyramidal Neurons Display Stochastic Resonance?
Journal of Computational Neuroscience, 2001Neocortical pyramidal neurons in vivo are subject to an intense synaptic background activity that has a significant impact on various electrophysiological properties and dendritic integration. Using detailed biophysical models of a morphologically reconstructed neocortical pyramidal neuron, in which synaptic background activity was simulated according ...

Predominant information transfer from layer III pyramidal neurons to corticospinal neurons
The Journal of Comparative Neurology, 2000Connections of layer III pyramidal neurons to corticospinal neurons of layer V and corticothalamic neurons of layer VI in the rat primary motor cortex were examined in brain slices by combining intracellular staining with Golgi-like retrograde labeling of corticofugal neurons.

Pyramidal neurons: dendritic structure and synaptic integration
Nature Reviews Neuroscience, 2008Pyramidal neurons are characterized by their distinct apical and basal dendritic trees and the pyramidal shape of their soma. They are found in several regions of the CNS and, although the reasons for their abundance remain unclear, functional studies--especially of CA1 hippocampal and layer V neocortical pyramidal neurons--have offered insights into ...

Influence of molecular layer on pyramidal tract neurons
Experimental Neurology, 1985Activity in layer I increases the excitability of pyramidal tract (PT) neurons, the effect being stronger on slow than on fast PT neurons. Extracellular recordings were made from lateral postcruciate cortex of domestic cats, using antidromic activation from medullary pyramid to identify and classify PT neurons. Their responses to contralateral forepaw (

Redistribution of synaptic efficacy between neocortical pyramidal neurons
Nature, 1996Experience-dependent potentiation and depression of synaptic strength has been proposed to subserve learning and memory by changing the gain of signals conveyed between neurons. Here we examine synaptic plasticity between individual neocortical layer-5 pyramidal neurons.

Excitatory-inhibitory interactions in pyramidal neurons
2015To understand how information is processed in neocortical circuits, it is crucial to map out in detail the role played by the individual neurons in the functioning of these circuits. This involves understanding how synaptic responses are integrated within the dendritic trees, and converted into trains of action potentials transmitted over the axon.
