Abstract - In this study, we investigated an efficient novel
methodology for the classification of Microelectroneurosensor
Signals recording (or Microelectrode Recording (MER) of
subthalamic-nuclei (STN) neurons obtained though deep brain
stimulator in Parkinson’s disease (PD) by employing Support
Vector Machines concept. We report some preliminary results.
Two models are employed in this study, namely, a model that
elicitates and extrapolates certain features through electro-
neuro-physiological MER signals and by using support vector
machines that mainly classify through supervised machine
learning. The two model techniques are made as a method
and applied to the problem of the detection of sub-cortical
structures of PD brain, such as STN, substantia-nigra (SN)
pars compacta (SNpc)/ pars reticulata (SNpc), thalamus-
nucleus (TN), and zona-incerta (Zi). The results showed
excellent classification circa ~ 99%. The investigation in this
study certainly avoids human intervention through
subjectivity in pinpointing or confining the subcortical
structures particularly STN. We used microelectrodes as
micro-neuro sensors vis-à-vis and vice-versa. Deep Brain
Stimulator (DBS) is a device-based well-developed and well-
established innovative/frontier neurosurgical-therapeutic-
method that reduces the symptoms of Parkinson`s disease(PD)
and restores/increases motor-functioning. DBS gives a unique-
opportunity to study the electrical-oscillatory neural-activity
of various sub-cortical-structures in PD-subjects.

1. INTRODUCTION
One of the most commonest neurologic disorders that elders
experience, Parkinson’s disease (PD) is a devastating
diagnosis affecting approximately 2 of every 1,000 older
adults. Although there is currently no cure and current PD
treatments help alleviate only the symptoms rather than the
disease’s progression, fresh hope such as deep brain
stimulation (DBS) lies in new research focused on
neuroscience especially computational neuroscience and
cognitive system for neuroprotection using the novel
engineering developments which are major breakthroughs
in engineering and medical sciences such as magnetic
resonance imaging (MRI), DatScan, Positron Emitted
Tomography (PET), Microelectrode Recording (MER) and
Deep Brain Stimulator (DBS)[1]-[15]. Parkinson`s disease
(PD) is though caused by a depletion of dopamine in the
Basal Ganglia region of the brain, it is usually treated by
medical prescriptions such as levodopa (L-dopa) medication
through hospital administration and management that
restores the dopamine levels. However, through L-dopa
there are many side-effects such as dyskinesias (cognitive
dysfunction, cognitive dementia, depression, hallucinations,
and axial symptoms like body speech problems and many
more). Microelectrode guided neurosurgery can also be used
for treating PD in severe cases or when medication through
medical management does not function. These surgical
procedures include a pallidotomy or a Deep Brain
Stimulation (DBS). During a pallidotomy a lesion is made in
the basal ganglia, while in a DBS a microelectrode is
implanted to stimulate the neuronal cells in the Basal Ganglia
[1].
However, the exact causes of PD are unknown, and it is a
chronic, progressive brain disorder that belongs to a larger
class of disorders called movement disorders. In PD, one
particular population of brain cells—those that produce a
chemical messenger called dopamine—become impaired
and are lost over time. “The loss of these brain cells causes
circuits in the brain to function abnormally, and those
abnormal circuits result in movement problems,” [1]-[15].
Parkinson’s disease (PD) is a progressive neurodegenerative
disorder characterized by the convolution of four classes of
cardinal motor symptoms or feature manifestations, namely,
frequency of tremor, Bradykinesia, rigidity, and postural
instability. Because, there is currently no definitive test for
