In the future mankind may be able to eliminate Alzheimer's disease, Parkinson's, schizophrenia, and stress. Recent discoveries and ongoing research have begun to unlock the mysteries of the brain and the discoveries are beginning to show some promise. They have led to new drugs and have shed some light on treating mental illness…
All of the methods, drugs, and research that involve the brain are treading on new territory. With each new discovery, comes the challenge of applying it with ethics and a value system that we can all agree on.
The brain is a very changeable organ. It can grow, mutate, and rewire itself as needed. This is often a normal response to trauma or injury. However, science can now induce the brain to change at will. Known as plasticity, the brain's ability to adapt has been studied since the beginning of the 19th century. This ability to change offers some hope for the treatment of Alzheimer's and other diseases of the brain. This research can further help us understand the causes and treatment for a wide range of mental illnesses. It may also lead to products that can enhance the brains functioning. This carries with it the ethical considerations of tampering with our normal thought processes.
Rearranging our thinking is nothing new. Biofeedback was an early attempt at using technology to alter our thinking. There are currently numerous drugs available to treat everything from mild stress to schizophrenia. We can also alter our thinking with electronic devices such as with transcranial magnetic stimulation (TMS). It is believed that this device may improve cognitive ability and treat sleep deprivation. We may one day have a computer controlled helmet that stimulates our brain with magnetism to give us an intellectual edge. Medical ethicists will need to decide where the mind ends and where the machine begins.
Advocates for forging ahead in the science of the brain are quick to point out that changing our thinking is a positive step towards mental health. We currently change our thinking by altering our diet, environment, education, and behavior. They contend that technology is simply science being put to work for what we have already been doing for centuries. The technology is moving fast as we have exited the 'brain decade' and entered the brain millennium.
In conclusion, the science of the brain and the recent discoveries have great promise in treating many ailments such as stroke or psychosis. It also holds the possibility of manufacturing thought beyond our wildest dreams. We are hesitant to manufacture a human clone in a laboratory or create a master race. Yet this is the possibility that brain research holds. The challenge for the next millennium will be for the scientists to balance the discovery with the ethical issues involved. ...

Autism as a development disorder is thus used by Baron-Cohen as a reference point in his research on the extreme male brain theory. For Baron-Cohen to say that there is a ‘male brain’ therefore simply means that the male and female are not the same in terms of the structure and functions of their brains (Auyeung et al., 2009).
It has long interested researchers, for example, to determine if there was a way to detect certain brain patterns in people with certain learning disorders. This can include students that have difficulty reading, or exhibit signs of dyslexia. Neuroscientists are also interested in determining if there are certain brain functions demonstrated by young people who various disorders such as ADHD.
This research since it’s a pilot study, briefs the audience with probable suggestions and paves the way for further research, laying the foundation for a full-fledged thesis which would debate that whether spacing effect actually makes learning better for people who have suffered from traumatic injuries or does the mass method is equally applicable?
With the help of these new technology, scientists are able not only to see which areas of the brain are activated during certain activities, but they also give us more detailed comparisons between different brains.
Among the many areas where these new technology are being applied, for example, the study of the juvenile brain is bringing about a very heated debate among legislators and scientists.
Information deemed relevant by the brain's control mechanism is processed and stored along a neural connection. Over the course of our lives, experience provides us with new information which is processed simultaneously up from the senses and down from the memory.
The need of brain communication is mainly to control the biological actions also referred as biopsychology. The forms of communication are mainly different in terms of communication exchange between the neurons and
The history of BCIs relates to Hans Berger initiative on the discovery of electrical activity in the sensors of the human brain. Research studies by Tan and Nijholt (13), place Brain-computer interface as a common trend that is picking up in the market with companies such
This is the primary reason why I want to join the research program on brains. As a child who has been raised with medical family members, I have always looked at the prospect of entering the field someday. On another point, brain tumor devastated us
The development of Positron emission tomography (PET) scanner, and functional magnetic resonance imaging (fMRI) scanners, allow brain scans to be conducted to analyse speech patterns. Findings indicate that separate areas of the brain are used in bilingualism
