Cocktails, Neurons and Nanos: Super-cognition?
April 9, 2008
Improving overall cognitive capability is becoming as simple as consuming a pill…
An interesting paradox has been the axis of much attention in the fields of pharmacy, brain research and ethics in the last few years. The advent of new technologies, particularly in the field of brain research, has induced scientists to improve the treatment of several conditions, such as Alzheimer’s disease, sleep disorders and dementia. However, what was primarily intentioned to provide solutions for patients with cognitive deficits has also proven functional for healthy people – not only functional, but quite efficient.
Neuroscience: What is Brain Plasticity?
April 3, 2008
Neuroscience has changed considerably in the past 20 years. An example of change over period is the concept of brain plasticity. Brain plasticity refers to the brain’s ability to rewire itself, relocating information processing functions to different brain areas and/or neural networks. Two decades ago, it was believed that brain networks were static after its initial formation period. Now that belief has changed. The study of brain plasticity has profound implications in human learning and behavior, and as such, for mental health.
To better understand this concept, let’s take a quick tour of the human brain, neural networks, and the plastic potential therein.
Harvard Biologist Admits: We Know Nothing About Brain Evolution
March 19, 2008
Science journals have featured countless stories about the evolution of the human brain. Scientists are puzzled since humans have much bigger brains than any other species. Their suggested explanations have often been mutually exclusive, for instance the old text book explanation relied on eating meat but a few years ago an article New Scientist, a popular science magazine, suggested that eating starch was the secret of brain growth. But both explanations fail to answer why other meat or starch eating species do not have big brains.
Do Believers in Evolution Have More Faith Than Believers in God?
March 19, 2008
It must be understood that the belief that Earth is billions of years old is crucial to the survival of evolution theory. The tactic is to teach that evolution always takes millions or even billions of years to happen so no one will ever be able to observe it. This sounds like a plan for the perfect lie.
