Double dissociation and hierarchical organization of strategy switches and reversals in the rat PFC.

29 Sep 2009 Prelimbic-infralimbic cortex (PL-IL) and orbitofrontal cortex (OFC) influence behavioral flexibility in the rat. The authors tested the effects of PL-IL or OFC infusion with the GABA agonist muscimol in the context of 2 flexible responding tasks: ... Read more...

Fragmentation of grid cell maps in a multicompartment environment.

11 Sep 2009 To determine whether entorhinal spatial representations are continuous or fragmented, we recorded neural activity in grid cells while rats ran through a stack of interconnected, zig-zagged compartments of equal shape and orientation (a hairpin ... Read more...

"Real-time" obstacle avoidance in the absence of primary visual cortex.

31 Aug 2009 When we reach toward objects, we easily avoid potential obstacles located in the workspace. Previous studies suggest that obstacle avoidance relies on mechanisms in the dorsal visual stream in the posterior parietal cortex. One fundamental question ... Read more...
