"Place and grid cells in a loop: implications for memory function and spatial coding"

Based on the anatomy of the entorhinal-hippocampal circuitry, we constructed a model of place and grid cells organized in a loop to investigate their mutual influence in the establishment of their codes for space.

4.10 – Multiple Stages of Memory Formation and Persistence"
16/10/2017 00:00:00 BRT

The idea that memories are not made instantly after learning but need to undergo a time-dependent, metabolically active complex consolidation process before they can be stably stored has dominated the neuroscience of learning and memory for decades. "

Short term changes in the proteome of human cerebral organoids induced by 5-MeO-DMT"

Here we used shotgun mass spectrometry to explore proteomic differences induced by 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) on human cerebral organoids. Out of the 6,728 identified proteins, 934 were found differentially expressed in 5-MeO-DMT-treated cerebral organoids."

The mechanisms underlying the intimate connection between sleep and learning are becoming increasingly clear. "

Asymmetry of the temporal code for space by hippocampal place cells"

Here we show that the spike timing of place cells couples to theta phase before major increases in firing rate, anticipating the animal’s entrance into the classical, rate-based place field. "
