True

• Piriform cortex anterior interneuron superficial GABA cell Show Other

• Axon terminal Show Other

• Gaba Show Other

• The GABABR1a antibody selectively marked the neuropil in layer Ia, where afferent olfactory fibers and intrinsic GABAergic axons terminate on the distal apical dendrites of pyramidal neurons. GABABR1a may be involved in feedforward synaptic circuits Show Other
• Horizontal cells in layer Ia are labelled for GAD and GABA, but not for GABA takeup, suggesting lack of local axon collaterals or high-affinity GABA takeup sites Show Other
