...the current issue of Science , fills in important details about cellular changes that occur when experience becomes memory. This process is called long-term potentiation or LTP. When LTP occurs in the hippocampi, two curved regions that flank the center of the brain, changes occur in synapses. These connect...Environmental decontamination, greenhouse gases, and the genome of a methane-loving bacterium
