Prenatal morphine exposure reduces pyramidal neurons in CA1, CA2 and CA3 subfields of mice hippocampus
Objective(s):This study was carried out to evaluate the effect of maternal morphine exposure during gestational and lactation period on pyramidal neurons of hippocampus in 18 and 32 day mice offspring. Materials and Methods: Thirty female mice were randomly allocated into cases and controls. In case group, animals received morphinesulfate 10 mg/kg.body weight intraperitoneally during 7 days bef...

متن کاملSurface pH Shifts on CA1 Pyramidal Neurons
21 In hippocampus, synchronous activation of CA1 pyramidal neurons causes a rapid, 22 extracellular, population alkaline transient (PAT). It has been suggested that the plasma 23 membrane Ca 2+-ATPase (PMCA) is the source of this alkalinization, as it exchanges 24 cytosolic Ca 2+ for external H +. Evidence supporting this hypothesis, however, has thus far 25 been inconclusive. We addressed this...
متن کاملMorphological heterogeneity of CA1 pyramidal neurons in response to ischemia.
We have found, based on the electrophysiological properties, two subtypes of CA1 pyramidal neurons in the CA1 region of the normal hippocampus, late postsynaptic potential (L-PSP) neurons and non-L-PSP neurons. In addition, our previous study has shown that the electrophysiological properties of these two subtypes of pyramidal neurons were differentially modified after ischemia. In the present ...
متن کاملState-dependent dendritic computation in hippocampal CA1 pyramidal neurons.
Depending on the behavioral state, hippocampal CA1 pyramidal neurons receive very distinct patterns of synaptic input and likewise produce very different output patterns. We have used simultaneous dendritic and somatic recordings and multisite glutamate uncaging to investigate the relationship between synaptic input pattern, the form of dendritic integration, and action potential output in CA1 ...
