The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.
Investigation of global gene expression profiles during formation of the Myxococcus xanthus specialized biofilm reveals a genetic regulatory network that coordinates cell motility, differentiation, and secondary metabolite production.
The readiness potential—a long-established neural precursor of voluntary action claimed to precede the onset of the conscious decision to move—is absent, or at least significantly reduced, for deliberate decisions.
A stochastic model of phyllotaxis can explain the striking irregularities observed in the spiral patterns of plants and predicts that perturbation patterns provide key information about the underlying biochemical mechanisms.
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.
