Abstract
Neurons communicate with each other through intricate network to evolve higher brain
functions. The electrical activity of the neurons plays a crucial role in shaping
the connectivity. With motor neurons being vulnerable to neurodegenerative diseases,
understanding the electrophysiological properties of motor neurons is the need of
the hour, in order to comprehend the impairment of connectivity in these diseases.
NSC-34 cell line serves as an excellent model to study the properties of motor neurons
as they express Choline acetyltransferase (ChAT). Although NSC-34 cell lines have
been used to study the effect of various toxicological, neurotrophic and neuroprotective
agents, the electrical activity of these cells has not been elucidated. In the current
study, we have characterized the electrophysiological properties of NSC-34 cell lines
using Micro-Electrode Array (MEA) as a tool. Based on the spike waveform, firing frequency,
auto- and cross-correlogram analysis, we demonstrate that NSC-34 cell culture has
>2 distinct types of neuronal population: principal excitatory neurons, putative interneurons
and unclassified neurons. The presence of interneurons in the NSC-34 culture was characterized
by increased expression of GAD-67 markers. Thus, finding an understanding of the electrophysiological
properties of different population of neurons in NSC-34 cell line, will have multiple
applications in the treatment of neurological disorders.
