Simultaneous recording from many neurons in macaque lateral intraparietal area reveals the elusive drift-diffusion signal, long suspected to underlie individual perceptual decisions and response times.

A first principles, neuro-computational framework proposes a path for the experimental dissection of neural circuit mechanisms of competitive selection across brain areas and animal species.

Ventral premotor mirror neurons discriminate observed actions well but predominantly differently from self-performed actions, requiring reconsideration of concepts addressing their function.

Discrete classes of cerebellar Purkinje neurons show distinct changes in synaptic and spiking activity during motor learning, with simple spikes playing a shifting role during acquisition, expression, and maintenance of learned responses.

Quantitative modeling of inactivations shows the prefrontal cortex (but not parietal cortex) of the rat is obligatory for decisions guided by evidence accumulating longer than 240 ms.
