Introduction The use of neural prostheses in clinical settings to aid in the repair of the nervous system is increasingly being practiced. These neural prostheses interact directly with the nervous system, facilitating the restoration of neural function damaged by injuries and disorders such as Parkinson’s disease. The loss of neuronal motor signal frequently causes partial or complete degeneration of motor activity, which the existing treatment measures are often unable to address. Developments in neuroscience and nanotechnology and Microsystems, however, yield a lot of potential for the creation of therapeutic modalities that integrate technical instruments into neuronal structures, thus promising effective treatment for conditions that affect the nervous system (Clausen, 2008). Proponents of the use of technology to improve human traits regard that technology could help in actively creating people to mend humans and change the world. Therefore, with continuous research, it is also anticipated that in the near future neural prostheses could be employed in improving the cognitive, memory, sensory, and learning abilities of even healthy individuals (DANA, 2002). While the use of neural prostheses can help enhance the quality of life for patients afflicted by neuronal illnesses and injuries, these implants also raise an array of ethical issues in relation to controlling the human brain directly with machines. The major ethical issues raised by the use of these devices include the safety of the interventions, and possible alterations of the identity and personality of the subjects. Use of neural prostheses could also lead to emergence of neural digital divides based on socioeconomic classes (Clausen, 2008). Further, enhanced memories could imply unfair competition in life, disadvantaging those who do not receive enhancers. The issues raised, thus, revolve around the potential benefits of these prosthetic implants to both individuals and the society, in relation to the perceived risks, and the implications of improving human capabilities through the use of electronic implants. These ethical issues are founded on various underpinnings such as fears and hopes, market forces, philosophical and moral grounds (DANA, 2002). Process of Memory Storage in the Brain Memory consists of complex neural events involving various parts and mechanisms of the brain. Basically, the memory system entails the cortex and the associated hippocampi, the amygdale, temporal lobe, and neurons. Memory stores are made up of multi-modal nerve cell connections distributed in the entire nervous system, requiring the neurons to make new networks and synthesize new protein molecules. Various stimuli emanating from thoughts, senses and actions affect particular sets of neurons and neurotransmitters (Berger, 2005). When a neuron in the brain is stimulated, a low voltage electrical impulse is transmitted to the axon. This electrical stimulation triggers the release of neurotransmitters, subsequently moving across the synaptic gap between the neurons and attaches into their corresponding receptors. The activated neurons also transmit the received signals to other relevant neurons. If the same signals are received persistently, synaptic modifications occur with great s
