Learning-enhanced coupling between ripple oscillations in association cortices and hippocampus

2017-11-01T16:20:29+00:00 November 1st, 2017|

Memory transfer for long-term storage Explicit memory formation involves the transfer of rapidly encoded information from the hippocampus to long-term storage sites in the association cortex. Khodagholy et al. developed a microelectrode system for large-scale simultaneous electrophysiological monitoring of multiple sites in the rat neocortex. They observed discrete high-frequency neocortical oscillations called ripples only in the association cortex. These cortical ripples shared many properties with hippocampal ripples. Hippocampal ripples were coupled with cortical [...]

Pyramidal Cell-Interneuron Circuit Architecture and Dynamics in Hippocampal Networks

2017-10-16T13:45:58+00:00 October 16th, 2017|

English, McKenzie, et al. identify, validate, and quantify monosynaptic connections between pyramidal cells and interneurons, using the spike timing of pre- and postsynaptic neurons in vivo. Their large-scale method uncovers a backbone of connectivity rules in the hippocampus CA1 circuit. Highlights Pyramidal cell-interneuron monosynaptic connections identified using spike timing Skewed distribution of connection probability and strength Short-term plasticity of connection strength is synapse specific Presynaptic cooperativity and postsynaptic timing impact spike transmission probability [...]

Study Finds That Rats May Have Nightmares Too

2017-11-07T08:49:22+00:00 September 18th, 2017|

Study Finds That Rats May Have Nightmares Too Nightmares may not be an experience exclusive to humans alone. New research finds that rats might have scary dreams when they fall asleep too. The study, published in Nature Neuroscience, was performed by scientists from New York University, who did an experiment that demonstrated that when rats go through frightening stages, the panic reaction they feel is reactivated during sleep. An experience perhaps similar [...]
