respiratory system

nervous system
• absence of whisker-related patterning in the brainstem trigeminal complex
• however, no difference is seen between external brain morphology or weight relative to control mice
• absence of patterned synapses of trigeminal afferents and their target cells (barrelettes)
• normal topographic mapping of primary trigeminal afferents
• NMDA receptors are functional but lack coincidence detection properties
