Grid-cell maps can be aligned to both local and remote reference frames, suggesting that they provide a metric for space beyond the navigationally accessible boundaries of the local environment.
Stunning new scan data of an enigmatic fish from the Early Devonian of Australia, Ligulalepis, is identified as a stem osteichthyan, specifically, as the sister taxon to the 'psarolepids' plus crown osteichthyans.
A computational model for the formation of neural networks of grid cells in virtual bats suggests that the highly ordered networks presumed to support spatial navigation in two dimensions cannot be routinely established in three-dimensional space.
Neuron populations in the lateral entorhinal cortex discriminate between memory-based contexts through both continuous "tonic" activity patterns as well as by their stimulus-evoked "phasic" responses.
A novel engineered protein that uncouples electrical signals from downstream biological responses in excitable cells provides a unique investigative tool with potential therapeutic applications.
Anchoring of proteins to the cell membrane through the glycosylphosphatidylinositol (GPI) anchor is critical for the survival of the cells that will give rise to the brain and face.
Alms1a is a centrosomal protein that exhibits asymmetric localization between mother and daughter centrosomes in asymmetrically dividing stem cells in Drosophila testis, controlling centriole duplication.
Two-photon in vivo calcium imaging reveals short time-scale, synchronous and sparse population activity in dentate gyrus that replays place-related information, and is important for formation of dentate-dependent spatial memory.
