Background
When the field of neuroscience began to self-organize in the 1960's, the experimental model was the laboratory rat and the technologies deployed were crude by today's standards. In a typical early example, neuroscientists would implant stimulating or recording electrodes chronically into the rat brain and attempt to use electrical stimulation (similar to modern deep brain stimulation) to change the behavior of the experimental animal. What happened in the rat brain was supposed to yield understanding of how the human brain might work. Drawing of the cells in the chicken cerebellum by S. Ramón y Cajal Neuroscience is a field that is devoted to the scientific study of the nervous system. ...

In neurotechnology, deep brain stimulation (DBS) is a surgical treatment involving the implantation of a medical device called a brain pacemaker, which sends electrical impulses to specific parts of the brain. ...
Modern Neuroscience creates Neurotechnologies Neuroscience has matured now to the point where, with non-invasive human brain imaging, the common experimental model is the human subject volunteer and the questions being asked, get at some of the fundamental questions of what it means to be human and to have a mind. The revolution in technologies that has made this maturation possible extends from gene to hospital bed-side and is now referred to as neurotechnology. Some examples of neurotechnology include the CAT scanner, fMRI, Positron emmision tomography, high-throughput genetic sequencing, brain proteomics and psychophamaceuticals. These technologies also include neural modeling simulations, biological computers, and human-brain interfaces (prosthetics). For other uses, see Mind (disambiguation). ...

Functional Magnetic Resonance Imaging (or fMRI) describes the use of MRI to measure hemodynamic signals related to neural activity in the brain or spinal cord of humans or other animals. ...
Positron emission tomography (PET) is a nuclear medicine medical imaging technique which produces a three dimensional image or map of functional processes in the body. ...

Neurotechnologies present neuroethical challenges As these new technologies have emerged, ethicists have begun to raise questions of how the new technologies might be practically used and what policies might govern their use [1]. Applications such as deception detection, neuro-marketing and the potential for artificially augmenting cognition all have policy implications. This article or section includes a list of works cited but its sources remain unclear because it lacks in-text citations. ...
Understanding human mind The neurotechnology revolution has enabled the possibility for the Decade of the Mind initiative. It also offers the possibility of revealing the mechanisms by which mind and consciousness emerge from brain. Consciousness is a quality of the mind generally regarded to comprise qualities such as subjectivity, self-awareness, sentience, sapience, and the ability to perceive the relationship between oneself and ones environment. ...
