Left Brain versus Right Brain Dominance Left Brain versus Right Brain Dominance: The impact it has on Learning Kara Self COL 100 Abstract In recent neurological research there has been a connection made between people who use one of the two hemispheres more in the brain and its impact on learning. While it is more theoretic‚ than complete fact interesting strides are underway in the study of Right Brain Dominant persons and Left Brain Dominant persons. In the following text‚ I will explain

when the brain is most sensitive to environmental input. Playing a musical instrument entails the acquisition and maintenance a wide range of skills‚ such as reading complex musical notes‚ coordinating hands and eyes movement‚ and memorizing long musical pieces. As a result‚ music training can boost one’s attention‚ memory‚ and executive functions. Previous research has demonstrated that intense musical training can result in plastic changes in the developing brain as well as the adult brain (Wan &

called “electrotactile stimulation for sensory substitution”‚ an area of study that involves using encoded electric current to represent sensory information and applying that current to the skin‚ which sends the information to the brain. 1.INTRODUCTION A blind woman sits in a chair holding a video camera focused on a scientist sitting in front of her. She has a device in her mouth‚ touching her tongue‚ and there are wires running from that device to the video camera

What is Brain Chemistry? Brain chemistry or neurochemistry is the complex system which allows the brain to function with the use of chemicals known as neurotransmitters which move information around in the brain. Every person’s brain chemistry is slightly different‚ and a number of things can play a role in the levels of various neurotransmitters in the brain‚ and how those chemicals affect the brain’s function. It is believed that difference in brain chemistry may explain a variety of behavioral

Comparison of Brain Structure in Mammals‚ Amphibians‚ and Birds The brain is a complex structure in all living species‚ even though they differ greatly in mammals‚ amphibians‚ and birds. It is the most important part of the body‚ because it maintains homeostasis and assists in every function. The brain structures of the three vertebrates‚ mammals‚ amphibians‚ and birds‚ have similar features and functions. There is still a great difference in the size‚ and importance of these structures in

The five major structures of the brain are myelencephalon‚ Metencephalon‚ mesencephalon‚ diencephalon and telencephalon. The myelencephalon carries signals from the brain to the entire parts of the human body and it is also uniquely shaped looking like a little net. The Metencephalon is made up of ascending and descending tracts just like the myelencephalon. It has two major divisions which are pons and the cerebellum. The mesencephalon has two divisions also and they are the tectum and the tegmentum

Traumatic Brain Injury Traumatic brain injury‚ also called acquired brain injury or simply head injury‚ is a result of a sudden blow to the head when an external force is applied causing a disruption of the physiological stability of the brain locally. It can also occur when an object pierces the skull and enters the brain tissue and when elevation in the intracranial pressure occurs and potentially dramatic changes in the blood flow within and to the brain. These changes may produce a diminished

inThe so-called ‘brain drain’ from poor to rich countries is now robbing poorer countries of essential personnel like doctors‚ nurses‚ engineers‚ and the trend is set to continue‚ if not to get worse. Some people say this movement of people around the world is not a new phenomenon.
