The neuron population of the hippocampal formation exhibits oscillatory activity within the theta (theta) frequency band (4-10 Hz), and the intrinsic resonance properties of individual hippocampal neurons contribute to this network oscillation. The subiculum is the pivotal output region of the hippocampal formation and it is involved in many of the(More)
Primary sensory neurons can generate irregular burst firings in which the existence of significant deterministic behaviors of chaotic dynamics has been proved with nonlinear time series analysis. But how well the deterministic characteristics and neural information of presynaptic chaotic spike trains were transmitted into postsynaptic spike trains is still(More)
Gene transfer into CNS is critical for potential therapeutic applications as well as for the study of the genetic basis of neural development and nerve function. Unfortunately, lipid-based gene transfer to CNS cells is extremely inefficient since the nucleus of these post-mitotic cells presents a significant barrier to transfection. We report the(More)
Obesity is associated with increased risk of diabetes, cardiovascular disease and several types of cancers. The hypothalamus is a region of the brain critical in the regulation of body weight. One of the critical and best studied hypothalamic circuits is comprised of the melanocortinergic orexigenic agouti-related protein (AgRP) and anorexigenic(More)
