Expression of orexin-A and melanin concentrating hormone (MCH) immunoreactivity by hypothalamic neurons that were infected by rabies injections into the diaphragm. The data included indicate the following: the amount of rabies virus injected across multiple sites of the left diaphragm, the survival times following rabies virus injections, the average (± one standard error of the mean) of rabies-infected hypothalamic neurons in each section, the range and median number (in parentheses) of infected hypothalamic cells in each section, the percentage of the infected cells that were immunopositive for orexin-A, and the percentage of the infected cells that were immunopositive for MCH.
