Data from: Investigating evolutionary lag using the species-pairs evolutionary lag test (SPELT)

Charles L. Nunn & Natalie Cooper
For traits showing correlated evolution, one trait may evolve more slowly than the other, producing evolutionary lag. The species-pairs evolutionary lag test (SPELT) uses an independent contrasts based approach to detect evolutionary lag on a phylogeny. We investigated the statistical performance of SPELT in relation to degree of lag, sample size (species pairs), and strength of association between traits. We simulated trait evolution under two models: one in which trait X changes during speciation and...

Data from: Nucleus reuniens of the thalamus contains head direction cells

Maciej M. Jankowski, , Nicholas F. Wright, Seralynne D. Vann, Jonathan T. Erichsen, John P. Aggleton, Shane M. O’Mara & Shane M O'Mara
Discrete populations of brain cells signal heading direction, rather like a compass. These ‘head direction’ cells are largely confined to a closely-connected network of sites. We describe, for the first time, a population of head direction cells in nucleus reuniens of the thalamus in the freely-moving rat. This novel subcortical head direction signal potentially modulates the hippocampal CA fields directly and, thus, informs spatial processing and memory.
