Slow Gamma Takes the Reins in Replay
نویسنده
چکیده
The mechanisms supporting hippocampal memory reactivation are puzzling. Reactivation occurs during ripple oscillations, yet ripples are not coordinated across regions. In this issue of Neuron, Carr et al. (2012) report that another oscillation, slow gamma, coordinates memory reactivation across the hippocampal network.

Transient Slow Gamma Synchrony Underlies Hippocampal Memory Replay
The replay of previously stored memories during hippocampal sharp wave ripples (SWRs) is thought to support both memory retrieval and consolidation in distributed hippocampal-neocortical circuits. Replay events consist of precisely timed sequences of spikes from CA3 and CA1 neurons that are coordinated both within and across hemispheres. The mechanism of this coordination is not understood. Her...
متن کاملInterference Mitigation of Replay Attacks in GPS Receiver using of Finite Impulse Response Filter
The vulnerability of civil GPS receiver to interference may be intentional or unintentional. Among all types of interference, replay attack intended as the most dangerous intentional one. The signal structure of replay attack is almost the same with the satellite signal. The interference effects can be reduce with the design of an appropriate filter in the receiver. This paper presents two meth...
متن کاملA New Slow-Motion Replay Extractor For Soccer Game Videos
In this paper, we will present a method to extract slow-motion replays in a soccer game video. According to our observation, a slow-motion replay always happens as a single shot and appears between two gradual transitions. Based on this fact, a video will first be segmented into individual shots and only those shots appearing between two gradual transitions are considered as candidate shots. Th...
متن کاملP2: Neocortex and Memory
The human prefrontal cortex differs from all other mammals: the seat of complex cognition, abstract thinking, planning and future forecasting, and behavioral inhibition. Using our prefrontal cortex is a significant energy drain on the body, so despite its impressive capabilities, it’s daily capacity is limited. Some researchers estimate a mere 2-3 hours per day of activity depletes the pr...
متن کاملDetection of slow-motion replay segments in sports video for highlights generation
In this paper, we present a novel method for generating sports video summary highlights. Specifically, our method localizes semantically important events in sport programs by detecting slow motion replays of these events, and then generates highlights of these events at multiple levels. In our method, a hidden Markov model (HMM) is used to model slow motion replays, and an inference algorithm i...
