Summary 1
Immunoengineering nerve repair
Mokarram, N., Dymanus, K., Srinivasan, A., Lyon, J.G., Tipton, J., Chu, J., English,
A.W. and Bellamkonda, R.V., 2017. Immunoengineering nerve repair. Proceedings of the
National Academy of Sciences, 114(26), pp.E5077-E5084.
This research paper has laid emphasis on peripheral nervous system (PNS) as it is one of the
major sources of disability. PNS is kind of injuries that lead to decreased functionality and long
term disability of all the patients suffering from trauma which further lead to neuropathic pain
that affects overall quality live lead by an individual who are suffering from these diseases. As
per this research paper for smaller gaps in rodents, normal recovery functioning can be achieved
but for longer gaps challenges have remained insurmountable. As per this research current
clinical gold standard used have several drawbacks in bridging long gaps, autograft etc. and
because of this there is a requirement of compelling or designing new approaches to exceed
performance of autograft. For this immunomodulatory approach was explored for nerve-
guidance scaffold in order to regenerate effect of reparative monocyte recruitment. For this
research Clinical and laboratory method was used where a permissive environment was created
for repair that helped the researcher in opening an alternative paradigm to stimulate peripheral
nerve repair. Researcher has used both primary and secondary data for this research paper and
has used quantitative data analysis method for completing this research. Analysis of RECA+
staining of endothelial cells at distal end.

Brain–machine interfaces: past, present and future
Lebedev, M.A. and Nicolelis, M.A., 2006. Brain–machine interfaces: past, present and
future. TRENDS in Neurosciences, 29(9), pp.536-546.
In this research paper researcher has focused on Brain mechanism interfaces. As per the
view of research generation of electrical activity by cortical neurons can directly control robotic
manipulator and has also experienced increased in BMI. BMI signal has strength of translating
raw neuron signals into motor commands which further helps in reproducing hand grasping and
arm reaching within artificial actuators. It is one of the most prominent development which can
1

be much more useful in restoring limb mobility in paralysed subjects but before this various
challenges such as designing of implantable biocompatible recording device, real time
computational algorithm development, a method through which brain can receive sensory
feedbacks from actuators, artificial prostheses such that they can directly be controlled by signals
derived from brain. This research paper had explained the capability of BMI to utilize high order
motor commands, control and drive evolutionary prostheses that acts and feels like a normal
human arm. In this study various previous research papers have been used in order to gain
understanding of BMI and ways in which challenges in evolution of prostheses can be analysed.
This study uses secondary data in order to reach to a conclusion.

Virtual reality (VR) in neuroscience research and therapy
Bohil, C.J., Alicea, B. and Biocca, F.A., 2011. Virtual reality in neuroscience research
and therapy. Nature reviews neuroscience, 12(12), p.752.
In this research paper researcher has focused on VR environment which is continuously
being used in stimulation of natural events as well as social interactions. Virtual reality mostly
helps in creating a multimodal, interactive sensory stimuli which further helps in offering unique
advantages over neuroscientific research approaches and its applications. It is mostly being used
in neuroscience therapy and research because compatibility of virtual reality within imaging
technology is quite good which further helps the researchers to present multimodal stimuli with a
high degree of ecological control and validity especially in recording changes within brain
activity. Researchers in this research paper have demonstrated a clear understanding of VR
technology, its progress, degree of control which it provides over therapeutic experience. So,
with the help of previous researchers done in this field or using secondary data researcher had
explained VR technology, its uses, applications and further expansion of this technology in
neuroscience research. Researcher has only used secondary data for this paper and has analysed
all the previous year’s data or articles for this paper in order to find use of use of VR technology
and future trends related to it. Lastly for this research paper qualitative and secondary data
analysis has been done.

Targeting neurons and photons for optogenetics
Packer, A.M., Roska, B. and Häusser, M., 2013. Targeting neurons and photons for
optogenetics. Nature neuroscience, 16(7), p.805.
This research paper has laid emphasis on Optogenetic approaches that has helped in
revolutionizing neuroscience. It uses light to manipulate all kinds of neural activities both in
functionality and genetically that further defines neurons with precision within millisecond. The
researcher has further explained that full potential harnessing of Optogenetic tools which
requires targeting of light to the correct neuron at correct time. This paper also explains and
discusses various kinds of barriers related to this topic and also discusses solutions related to this
topic. This researcher paper will explain various methods through which light activation
molecules can be targeted to a specific cell type under conditions that are genetically, activity or
virally dependent and controlled. New ways of targeting lights to neurons had also been explored
so that precise activation and inactivation can be controlled and allowed. Explanation of these
techniques had also helped in explaining different factors that had not been explained in previous
researches that had been done in this field. This research paper secondary data had been used
where various light strategies, their pros and cons had been compared and questions these
strategies heled in addressing had been explained and discussed in detailed manner.

A spark at the periphery
Waltz, E., 2016. A spark at the periphery.
In this research paper researcher has focused on electronic devices that helps in stimulating
peripheral nervous system. In this paper researcher has also laid emphasis on Galvani
Bioelectronic venture of GlaxoSmithKline and Verily Life Sciences who has developed
miniaturized electronic devices for peripheral nerve stimulation. It has boosted electronic field as
it has been the first breakthrough in success of human capital in rheumatoid arthritis. As per this
research Electronic impulses devices had been used for decades especially in improvement of
health. Most of the work done till today in peripheral nervous system has been focused on
somatic or voluntary nervous system in order to restore movement among people who have
3

paralysis either due to strokes or spinal cord injury. But today due to automation in peripheral
nervous system has increased the door for treatment of wide variety of diseases that are currently
treated by injected or oral drugs. PNS focuses on sending any kind of message directly to the
target. This research paper has largely explained the use of peripheral nervous system, its
effectiveness and usefulness in treating wide variety of diseases. It has also explained
contribution of various companies in this field and technology used by them. This research paper
has done secondary data analysis in order to reach to a conclusion.

What blindness can tell us about seeing again: merging neuroplasticity and neuroprostheses
Merabet, L.B., Rizzo, J.F., Amedi, A., Somers, D.C. and Pascual-Leone, A., 2005. What
blindness can tell us about seeing again: merging neuroplasticity and neuroprostheses. Nature
Reviews Neuroscience, 6(1), p.71.
This research paper has laid emphasis on development in the field of visual
neuroprostheses in order to restore vision among blind individuals. As per this research paper
delivery of appropriate electrical stimulation can help to intact structure so that sensation of light
among blind people can retained that has been suppressed for years. This research paper explains
that merger of neuroplasticity and neuroprostheses can help in restoring blindness among blind
people. According to the researcher there are various things that are required in successful
development of functional visual prostheses i.e. ways in which communication with visually
deprived brain can be done such that perceived visual functioning can be generated electrically.
This report had also discuss current strategies that are being used to restore vision and new
approaches that can be used for restoring vision in blind people. Researcher has also explained
future perspectives research area that are possible in restoring vision of blind people.
