Molecular systematics and phylogeography of the endemic Osgood's deermouse Osgoodomys banderanus (Rodentia: Cricetidae) in the lowlands of western Mexico.

Osgoodomys banderanus is a recognized and endemic rodent species of western Mexico, an area known for its high biodiversity and number of endemisms. Phylogeographical relationships within this taxon were analyzed based on mitochondrial (ND3, tRNA-Arginine, ND4L and partial ND4) and nuclear (GHR) nucleotide sequences. We obtained a total of 112 samples from 22 localities, covering the complete distribution of the species.

Poststimulation time interval-dependent effects of motor cortex anodal tDCS on reaction-time task performance.

Anodal transcranial direct current stimulation (tDCS) induces long-term potentiation-like plasticity, which is associated with long-lasting effects on different cognitive, emotional, and motor performances. Specifically, tDCS applied over the motor cortex is considered to improve reaction time in simple and complex tasks. The timing of tDCS relative to task performance could determine the efficacy of tDCS to modulate performance.
