Effects of theophylline-activated riboswitches on growth of B. bacteriovorus

All of the photos in the figure above show petri dishes containing B. bacteriovorus and its prey E. coli. The two photos on the left show the growth of B. bacteriovorus in dishes not containing (-) and containing (+) theophylline without a riboswitch inserted in the genome. The right two photos show the growth of B. bacteriovorus modified with a riboswitch in dishes not containing (-) and containing (+) theophylline. The left photos show no difference in growth and the right photos show faster growth in presence of theophylline, meaning that the theophylline-activated riboswitches had an effect on the predatory behavior of B. bacteriovorus.

Correlation between connectivity and distance of neurons in the human cortex

This diagram shows correlation between connectivity and distance of neurons in the human cortex. There are approximately 100,000 neurons in a square millimeter of cortex, as illustrated in the center box. The red gradation shows neuronal connectivity, with dark red indicating denser connectivity through synapses. While half of the synapses connect to neurons close to them, the other half connect with distant neurons, as so illustrated in the boxed area on the far left of this diagram. The differences in connectivity and distance between neurons require whole brain simulation in order to understand brain function.
