fasciculates with wedge commissure antennal mechanosensory and motor center B1 projection neuron antennal mechanosensory and motor center B1a projection neuron 2012-03-28T03:44:56Z Projection neuron whose cell body is located dorsally to the antennal mechanosensory and motor center (AMMC) and innervates the AMMC zone B and both the ipsilateral and the contralateral inferior ventrolateral protocerebrum (IVLP) regions. These neurons receive input in the AMMC zone B and establish presynaptic connections in the lateral region of the IVLP. These neurons are activated by an acoustic stimuli and are narrowly tuned to respond to 100 Hz stimuli (Lai et al., 2012). FBbt:00110121 VFB:FBbt_00110121 AMMC-B1a PN Auditory function was determined measuring GCaMP activation in these cells in response to an acoustic stimuli. Subsets of AMMC-B1a neurons were labeled with the drivers: E0564-GAL4, E0583-GAL4, VT27938-GAL4 and VT19992-GAL4. Single cell imaging with the first two drivers showed that the AMMC-B1a neurons are isomorphic. Presence of pre- and postsynaptic sites was determined by immunoreactivity to Dscam- and synaptotagmin-GFP localization, respectively. AMMC-B1a fly_anatomy.ontology AMMC-B1a neuron AMMC-B1a
