Sep 4, 2018 · Introduction. In the present work we developed a new type of implant for mice to test whether optogenetic inhibition of sharp wave ripples (SWRs) by affecting a large population of principal cells in the dorsal CA1 can cause impairment in the recall of recently learned spatial memories.

Mar 1, 2001 · Abstract. To explore the plastic representation of information in spatially selective hippocampal pyramidal neurons, we made multiple single-unit recordings in rats trained to find a hidden platform at a constant location in a hippocampal-dependent annular watermaze task. Hippocampal pyramidal cells exhibited place-related firing in the watermaze.

Sep 4, 2018 · With the advent of optogenetics, it became possible to change the activity of a targeted population of neurons in a temporally controlled manner. To combine the advantages of 60-channel <i>in vivo</i> tetrode recording and laser-based optogenetics, we have developed a closed-loop recording system th ….

NEIL BURGESS, JAMES G. DONNETT & JOHN O’KEEFE A model of how internal and external sensory information contribute to the ® ring of place cells in the rat hippocampus, and of how these cells contribute to the rat’s spatial behavior, is tested on a miniature mobile robot. The experiments show that crude visual, odometric
The right human. hippocampus retains its role in spatial mapping as demonstrated by its activation during accurate naviga- tion in imagined and virtual reality environments. In addition, it may have taken on wider memory.
