That means rapid events look slower to them because their nervous systems register more visual “frames” per second. Humans typically fuse flicker around 50–60 Hz. Diurnal flying insects often have critical flicker-fusion frequencies above 100 Hz. A faster vi

We see undulating movements of the growth cone and the long filopodia as actin bundles are restructured, thanks to the label-free, high spatial resolution of Nanolive imaging. #Medspiration . . . #brain #neuroscience #neurociencia #growthmindset #neuron"
