Authors highlight TrkB-dependent molecular pathways as critical for the maturation of inhibitory interneurons and support the hypothesis that loss of BDNF signaling in cortistatin interneurons leads to altered excitatory/inhibitory balance.

Authors report a viable chaperone-based strategy for reversing the synaptic vesicle trafficking defects associated with excess α-synuclein, which may be of value for improving synaptic function in Parkinson’s disease and other synucleinopathies.

PhD Candidate Ruilong Hu and Dr. Ricardo Araneda tell the story about their eNeuro publication that showed that the two predominant subtypes of inhibitory neurons in the main olfactory bulb, the granule cells and periglomerular cells, exhibit subthreshold resonance mediated by hyperpolarization-activated currents (Ih), as opposed to the primary output neurons, the mitral cells.

Authors show that axons of inhibitory neurons have distinctive structural and molecular features that contrast with those of the majority of myelinated excitatory axons in human neocortex.
