Local generation of multineuronal spike sequences in the hippocampal CA1 region.
Sequential activity of multineuronal spiking can be observed during theta and high-frequency ripple oscillations in the hippocampal CA1 region and is linked to experience, but the mechanisms underlying such sequences are unknown. We compared multineuronal spiking during theta oscillations, spontaneous ripples, and focal optically induced high-frequency oscillations ("synthetic" ripples) in free...
متن کاملMultineuronal spike sequences repeat with millisecond precision
Cortical microcircuits are nonrandomly wired by neurons. As a natural consequence, spikes emitted by microcircuits are also nonrandomly patterned in time and space. One of the prominent spike organizations is a repetition of fixed patterns of spike series across multiple neurons. However, several questions remain unsolved, including how precisely spike sequences repeat, how the sequences are sp...
متن کاملPostmortem Study of Molecular and Histological Changes in the CA1 Hippocampal Region of Chronic Methamphetamine User
Methamphetamine (Meth) is recognized as one of the most important new distributedabused drug that causes severe damage to the different parts of the brain, especiallyhippocampus. Previous studies have demonstrated that Meth can induce apoptosis and celldeath in the brain. In this study, we evaluated the long-term effects of Meth abuse in theCA1 region of postmortem hippo...

متن کاملIntegrative spike dynamics of rat CA1 neurons: a multineuronal imaging study.
The brain operates through a coordinated interplay of numerous neurons, yet little is known about the collective behaviour of individual neurons embedded in a huge network. We used large-scale optical recordings to address synaptic integration in hundreds of neurons. In hippocampal slice cultures bolus-loaded with Ca2+ fluorophores, we stimulated the Schaffer collaterals and monitored the aggre...
