Winkler bags are being hung to dry leaf litter. On this trip, bags were hung for 72 hours to dry. 

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.

fMRI images showing differences in response to reward anticipation and delivery between adults with ADHD (ADHD group) and typically developing adults (control group).  The color indicates the amount of activity, measured by changes in blood oxygen level, in the different areas of the brain.
