WebbIn contrast, spindle-ripples are typical for posterior hippocampus and are tightly coupled to spindles in inferior parietal cortex. These empirical studies suggest that the hippocampal SWRs and spindle-ripples represent distinct phenomena, especially with respect to their interactions with the cortex, and would need to be modeled separately.

Webb21 mars 2024 · During deep sleep and resting periods, the hippocampus generates high-frequency (∼200 Hz) oscillations called ripples, which are important for memory consolidation. The mechanisms underlying ripple generation are not well understood. A prominent hypothesis holds that the ripples are generated by local recurrent networks … Webb25 juni 2009 · Hippocampal CA3 output is crucial for ripple-associated reactivation and consolidation of memory A widely held memory consolidation theory posits that memory …

Webb31 mars 2013 · Chapter 3: This chapter focuses on the timing of ripple event-generation by the hippocampus. Ripples are frequently observed as pairs, triplets, or longer sets; however, the within-set timing of ripple events remains unknown. This chapter presents results that demonstrate that ripple generation is modulated by a 10-15 Hz rhythm. top chord extension steel joistWebb17 feb. 2024 · Hippocampal sharp wave/ripples (SPW/Rs) are remarkable both from a neurophysiological viewpoint and in their behavioral impact: On the one hand, they consist of strong increases of spiking activity in large parts of local neuron populations (the sharp wave) together with oscillatory, extraordinarily coherent neuronal discharges (ripples). top chord jembatanWebb1.
