Weather map map using his own system of symbols, thereby creating the world's first weather map. He used his map to prove that air circulated clockwise around areas of high pressure; he coined the term 'anticyclone' to describe the phenomenon. He was also instrumental in publishing the first weather map in a newspaper, for which he modified the pantograph (an instrument for copying drawings) to inscribe the map onto printing blocks. "The Times" began printing weather maps using these methods with data from the Meteorological Office. The introduction of country-wide weather maps required the existence of national telegraph networks so that data
Methods used to study memory brain. Due to the use of large, surgically implanted devices this technique is generally used on primates, however the use of small cryotip implants has implications for use in rats. This exciting new technology allows for reversible lesions, which removes variations between animals so that better causal relationships can be shown. Animals can act as their own controls and this is ideal for any neuroscientific research. The neurotoxic lesion technique has proven to be essential for studying the neural basis of behavior and memory in animals. Neurotoxins can be used to selectively damage very specific nerve tracts in the brain.
