behavior/neurological
• latencies to entering the shock compartment are significantly shorter compared to wild-type controls but are longer than training latencies
• responses in a hot plate test are similar to controls indicating similar pain sensitivities to controls
|
• non-habituated males show attenuated exploration in an open field
• reduced exploratory activity (reduced nose pokes, time spent inspecting holes, and number of holes repeatedly poked) in the 16-hole board test
|
• decrease in time spent exploring the open arm in an elevated plus maze and increased latency until first open arm entry
• however, total transitions between arms and between the light and dark sides is similar to wild-type controls
• decrease in the time spent in the light side during a light-dark box test

• no gross anatomical changes in major brain structures and no alteration in the development, anatomical position, survival or number of neurons that normally express the protein
