Invasive neuronal tract tracing is prohibited in very large or endangered animals, particularly marine mammals like dolphins. Scientists from Germany and Italy propose diffusion-weighted imaging as a feasible alternative, even in brains fixed in formalin for extended periods.

Pigeons can categorize innumerable naturalistic and artificial visual stimuli they encounter. Computational models suggest that elementary associative learning lies at the root of the pigeon’s category learning and generalization.
