Cortical cooling
Neuroscientists generate various studies to help explain many of the complex connections and functions of the brain. Most studies utilize animal models that have varying degrees of comparison to the human brain; for example, small rodents are less comparable than non-human primates. One of the most definitive ways of determining which sections of the brain contribute to certain behavior or function is to deactivate a section of the brain and observe what behavior is altered. Investigators have a wide range of options for deactivating neural tissue, and one of the more recently developed methods being used is deactivation through cooling. Cortical cooling refers to the cooling methods restricted to the cerebral cortex, where most higher brain processes occur. Below is a list of current cooling methods, their advantages and limitations, and some studies that have used cooling to elucidate neural functions.
