Hippocampal pyramidal neurones display a Ca2+-dependent K+ current responsible for the slow afterhyperpolarization (IsAHP), a prominent regulator of excitability. There is considerable transmitter convergence onto IsAHP but little information about t

Biochemical and in situ hybridization studies demonstrated that the levels of protein kinase C variants were significantly increased in the hippocampus of the experimental models of epilepsy in rats. In addition it has been demonstrated that protein

Prolonged modification of intrinsic neuronal excitability is gaining prominence as an activity-dependent form of plasticity. Here we describe a potential synaptic initiation mechanism for these changes in which release of the transmitter glutamate ac

Kainate receptors (KARs) on CA1 pyramidal cells make no detectable contribution to EPSCs. We report that these receptors have a metabotropic function, as shown previously for CA1 interneurons. Brief kainate exposure caused long-lasting inhibition of

Dendrites of reconstructed hippocampal neurons were analyzed for morphometric, topologic, and fractal parameters (n = 32 quantities) to investigate neuronal groupings and growth characteristics with a common set of assumptions. The structures studied

We have developed an on-line archive of neuronal geometry to encourage the use of realistic dendritic structures in morphometry and for neuronal modeling, located at web address www.neuro.soton.ac.uk. Initially we have included full three-dimensional

The synaptic plasticity that is addressed in this review follows neurodegeneration in the brain and thus has both structural as well as functional components. The model of neurodegeneration that has been selected is the kainic acid lesioned hippocamp

Recovery after nervous system lesions may lead to partial re-institution of developmental schemes and processes. Here we review several of these proposed schemes, with the conclusion that though some processes may involve re-expression of embryonic p

There is a sharp contrast between the profuse in vivo axonal arborization of CA3 pyramidal cells in the CA1 area and the low probability of finding pairs of connected CA3-CA1 pyramidal cells in vitro. These anatomical differences contribute to a conn

Tetanic stimulation of afferents in the stratum radiatum of the CA1 area of the rat hippocampus results in long-term potentiation of excitatory synaptic responses in pyramidal cells. Previous studies have reported a greater increase in the population
