Use of Colchicine in Cortical Area 1 of the Hippocampus Impairs Transmission of Non-Motivational Information by the Pyramidal Cells
Colchicine, a potent neurotoxin derived from plants, has been recently introduced as a degenerative toxin of small pyramidal cells in the cortical area 1 of the hippocampus (CA1). In this study, the effect of the alkaloid in CA1 on the behaviors in the conditioning task was measured. Injections of colchicine (1,5 μg/rat, intra-CA1) was performed in the male Wistar rats, while the animals were s...
متن کاملLead exposure impairs the NMDA agonist-induced NOS expression in pyramidal hippocampal cells
Chronic exposure to lead (Pb) affects neural functions in central nervous system (CNS) particularly the learning and memory. On the other hand, alteration of calcium level in the CNS results in activation of NOS. It has been shown that lead enters the neurons through calcium channels and displaces Ca2+ from calcium binding proteins such as calmodulin and troponin C thereby affecting calcium-med...

متن کاملAxonal ramifications of hippocampal Ca1 pyramidal cells.
Intracellular injections of Lucifer Yellow into CA1 pyramidal cells of the in vitro guinea pig hippocampal slice enabled us to examine in detail the morphology of the axons of these neurons. We also recorded the electrophysiological responses of these neurons to alvear stimulation. In our morphological examinations, we found that many axons bifurcate in the alveus, with the major branch project...
متن کاملDopamine action on hippocampal pyramidal cells.
Dopamine (DA) was applied to CA1 region pyramidal cells in slices of guinea pig hippocampus maintained in vitro in order to examine its electrophysiological effect on CNS neurons. DA induced hyperpolarization of membrane potential and an increased conductance in 75% the 21 CA1 neurons to which it was applied. DA also augmented the afterhyperpolarizations and increased conductance which normally...
