The genetic background of Saccharomyces cerevisiae yeast strains influences responses to gene overexpression.

RNA sequencing of the African clawed frog has identified hundreds of putative direct Six1 and Eya1 target genes, including transcriptional regulators of neuronal progenitors and neuronal/sensory differentiation.

The learning rate for novel spatial environments in model networks of place cells is determined by the product of the window for plasticity and the auto-correlation of place-cell activity.

Laminin gamma1-dependent basement membranes are required for multiple aspects of olfactory system development in zebrafish, including the maintenance of placode tissue shape and the growth of the olfactory axons.

Echolocating bats may recognize locations in the environment (and navigate to them) by remembering the specific echo signature of those locations.

Imaging of neurons within the hippocampus, a memory region of the brain, reveals how the brain updates memories during different learning conditions compared to when learning is blocked by amnestic drugs.

Computational modeling of the brain’s navigation system reveals that place cells can drive the formation of hexagonal patterns experimentally observed in grid cells activity.

Place cells in the rat hippocampus encode positions along well-learned routes as opposed to intended destinations.

In anticipation of a reward, hippocampal place cells simulate desired journeys through areas that have been seen, but not explored.

A very large number of place-field maps can be robustly learned by association of external cues with the grid-driven response, however plasticity in the grid-cell inputs renders the place-cell responses volatile.
