A mouse virtual reality system is presented which allows normal spatial behavior and place, grid and head-direction cell firing patterns in 2-D arenas, and is compatible with electrophysiology and multi-photon imaging.
Two cell-penetrating peptides that inhibit Ras-ERK signalling and a potent clinically relevant MEK inhibitor block cocaine conditioned place preference and accelerate extinction of cocaine self-administration upon a single administration in mice.
Through the interaction between PCP signaling and N-cadherin, oriented cell division and cell rearrangement are coordinated to establish the appropriate tissue architecture critical for limb skeletal morphogenesis.
Comparison of the intracellular activity of hippocampal neurons in novel and familiar environments reveals experience-dependent changes in inputs underlying the formation of stable representations of space.
CA1 physiology is altered in the hippocampus of Down syndrome mice during both spatial exploration and rest, paralleled by an increase in populations of interneurons responsible for single cell and network synchronization.
