Pyramidal Cell-Interneuron Circuit Architecture and Dynamics in Hippocampal Networks

2017-10-16T13:45:58+00:00October 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

2018-04-27T19:47:45+00:00September 18th, 2017|

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 to what some of us face [...]
