Ratio of pyramidal cells versus non-pyramidal cells in sector CA1 of the human Ammon's horn
Anatomy and Embryology, 1985Combined Golgi/pigment studies revealed that pyramidal neurons and non-pyramidal cells of the Ammon's horn of the human adult can be distinguished from each other by their characteristic lipofuscin pigment deposits. In sector CA1, both the typical pyramidal neurons and the modified forms of pyramidal cells contain a modest amount of fine lipofuscin ...

Effect of phencyclidines on hippocampal pyramidal cells
Brain Research, 1982Phencyclidine (PCP) and several behaviorally active or inactive structural analogs were administered i.v. to urethane-anesthetized rats in order to determine their effects on CA1 pyramidal cell discharges elicited by contralateral CA3 (cCA3) stimulation.

The effect of muscimol on hippocampal pyramidal cells
European Journal of Pharmacology, 1979The effects of muscimol on rabbit hippocampal pyramidal cell firing were studied and compared after iontophoretic, topical, and intravenous administration of the drug. All modes of application resulted in a bicuculline-sensitive, strychnine-insensitive, depression of the monosynaptically activated population spike evoked by micro-stimulation of the ...

The increasing resolution of tract-tracing studies has led to the definition of segments along the transverse axis of the hippocampal pyramidal cell layer, which may represent functionally defined elements. This review will summarize evidence for a morphological and functional differentiation of pyramidal cells along the radial (deep to superficial ...

Preservation of hippocampal pyramidal cells in paraphrenia
Schizophrenia Research, 2003A recent article classifies paraphrenia within the tauopathy spectrum [Acta Neuropathol., 103 (2002) 313]. More specifically, neurofibrillary changes appear restricted to the hippocampus and are accompanied by scant amyloid deposition. The present study adds the preservation of hippocampal (CA1) pyramidal cell numbers to the neuropathological findings ...

Plasmonic Tipless Pyramid Arrays for Cell Poration
Nano Letters, 2015Improving the efficiency, cell survival, and throughput of methods to modify and control the genetic expression of cells is of great benefit to biology and medicine. We investigate, both computationally and experimentally, a nanostructured substrate made of tipless pyramids for plasmonic-induced transfection.

Pyramidal Nerve Cell Loss in Alzheimer's Disease
Experimental Neurology, 1996Loss of the large pyramidal cells of the association neocortex and hippocampus, along with plaques and tangles, is fundamental to the neuropathology of Alzheimer's disease. The extent of Alzheimer-specific cell loss, relative to controls, is age-dependent with maximal losses in younger subjects though, because of the (additive) effects of 'normal ...

Somatostatin hyperpolarizes hippocampal pyramidal cells in vitro
Brain Research, 1981Superfusion onto hippocampal slices of low concentrations of the tetradecapeptide somatostatin (SS), or an SS analogue having CNS activity, reversibly hyperpolarized pyramidal neurons, as revealed by intracellular recording. The hyperpolarizations were accompanied by reductions in spontaneous and evoked spike discharge and in input resistance; the ...

Granulovacuolar degeneration in pyramidal cells of the hippocampus
Acta Neuropathologica, 1978We have shown that as the number of granulovacuolar bodies in affected pyramidal cells of the hippocampus increases so cytoplasmic RNA contant is reduced. Prior to its degeration, the nucleolus is increased in volume while that of the nucleus remains unchanged in size throughout.
