The simplest way to gain information about brain anatomy is by visual inspection, but many more sophisticated techniques have been developed. Brain tissue in its natural state is too soft to work with, but it can be hardened by immersion in alcohol or other fixatives, and then sliced apart for examination of the interior. Visually, the interior of the brain consists of areas of so-called grey matter, with a dark color, separated by areas of white matter, with a lighter color. Further information can be gained by staining slices of brain tissue with a variety of chemicals that bring out areas where specific types of molecules are present in high concentrations. It is also possible to examine the microstructure of brain tissue using a microscope, and to trace the pattern of connections from one brain area to another.
What instrument can you use to examine the microstructure of the brain?
microscope

The most notable cricket club in Cork is Cork County Cricket Club, which was formed in 1874. Although located within the Munster jurisdiction, the club plays in the Leinster Senior League. The club plays at the Mardyke, a ground which has hosted three first-class matches in 1947, 1961 and 1973. All three involved Ireland playing Scotland. The Cork Cricket Academy operates within the city, with the stated aim of introducing the sport to schools in the city and county. Cork's other main cricket club, Harlequins Cricket Club, play close to Cork Airport.
Which teams played in the three first class matches?

The city is home to 15 am and FM radio stations, two of which are French-language stations. St. John's is the only Canadian city served by radio stations whose call letters do not all begin with the letter C. The ITU prefix VO was assigned to the Dominion of Newfoundland before the province joined Canadian Confederation in 1949, and three AM stations kept their existing call letters. However, other commercial radio stations in St. John's which went to air after 1949 use the same range of prefixes (CFCK) currently in use elsewhere in Canada, with the exception of VOCM-FM, which was permitted to adopt the VOCM callsign because of its corporate association with the AM station that already bore that callsign. VO also remains in use in amateur radio.
How many French-language stations does the city have?
two
