Collection of Samples The different species of Chiropterawere collected from three (3) caves at Minalungao National Park such as Maipit Cave‚ Minalungao Caveand Makatulang Cave. Exact location was determined using the Global Positioning System (GPS). Consequently‚ abiotic factors such as air temperature and humidity were determined using thermo-anemometer and sling psychrometer respectively. The collected Chiropterans were placed in a appropriate bags and properly labelled. The Maipit Cave is located

neurodevelopmental disorder often paired with unique behavioral abnormalities like hypersociability‚ reduced fear and a tendency to approach strangers. The amygdala is an integral component of the neural network and has been implicated in social phenotype particularly in emotion and fear. Functional magnetic resonance imaging (fMRI) and blood-oxygenation-level-dependent (BOLD) responses indicated abnormal structure and function of amygdala in individuals with WS during face processing tasks.

Subjects included 219 schizophrenia patients of European descent and 76 schizophrenia patients of African descent. Schizophrenia patients showed significant deficits on ten of the endophenotypic measures‚ replicating prior studies and making genetic analyses more accessible on these phenotypes. A total of 38 genes were found to be associated with at least one endophenotypic measure
