A new fossil sheds light on the evolution of an aquatic lifestyle in extinct reptiles and supports a close phylogenetic relationship between archosaurs (crocodiles, dinosaurs, birds, and kin) and turtles.

The Wnt antagonist DKK3 is a key regulator of excitatory and inhibitory synapses, and its downregulation in the hippocampus restores synaptic connectivity and memory in an Alzheimer's disease mouse model.
The decrease in alpha rhythm amplitude in the parietal regions after the presentation of a deviant auditory stimulus gives rise to a part of the P300-evoked response.

In adolescent rats, whose actions are more impulsive, neuronal striatal activity that precedes self-initiated action sequences has a steeper modulation by waiting time compared to the modulation found in adults.
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 series of experiments suggest that the fronto-parietal attentional network is involved in controlling eye-based attention, and FEF plays a crucial causal role in generating the attention-induced ocular dominance shift.
