The brain Weighs 1300-1400g Made up of about 100 billion neurons The most complex living structure in the universe The cerebral hemispheres Are the two halves of the cerebral cortex Although they appear to be separated by a deep grove (the longitudinal fissure) they are actually connected by the corpus callosum They receive messages from and control the opposite side of the body The corpus callosum Is the strand or bridge of nerve tissue that connects the left and right hemispheres

Teenage Brain Development Not Considered in Court Teenagers accused of violent crimes should not be tried as adults in a court of the law. Teenagers brains are not fully developed‚ from the ages 13-18 a projected number of‚ “one percent of gray matter is lost every year in teenagers‚” and these are the teens being tried as adults in court (Spinks). A growth of gray matter is an important development stage in teens. The gray matter grows mostly when the brain is stimulated through accelerated learning

Chapter 1: “The Phantom Within” Modularity vs. Holism Modularity – different parts of the brain are highly specialized for mental capabilities. (i.e.‚ FFA‚ module for language‚ and etc…) Holism – “connectionism”; many areas‚ especially cortical regions‚ can be recruited for multiple tasks. *** Ramachandran believes these two views are not mutually exclusive. The brain is a dynamic structure that employs both “modules: in a marvelously complex interplay. (uses Baywatch as an analogy‚ saying

Brain development throughout childhood The first eight years of a child’s life are not only the most important years of a child’s life‚ but also the most rapid period of human development throughout a human life. These years are critical to the emotional and physical growth of a child. By the age of four‚ half of a person’s intelligence potential has already been developed and early childhood experiences can have a lasting effect on personality‚ behavior‚ and learning. (Early‚ 2001) These first

“In order to understand what the brain does‚ it is first necessary to understand what it is – to know the names and locations of its major parts and how they are connected to one another” (Pinel‚ 2011. p. 51). The five major structures that compose the brain are labeled as myelencephalon‚ metencephalon‚ mesencephalon‚ diencephalon‚ and telencephalon. These major structures are what create the adult forebrain‚ midbrain‚ and the hindbrain. First‚ the myelencephalon is also known as the medulla

My research paper will be on the temporal lobes‚ which is what I believe to be the most important part of the brain. I will be explaining what its functions are and why they are so important. To begin the temporal lobes are structures in the cerebral cortex‚ they are located just above the ears‚ and are almond shaped. They are involved in the functions of hearing‚ language processing‚ and memory. Now that you know these details I will now go more into detail of how the temporal lobes control these

From an investigation of the connection between strain components in uniaxial tests‚ this research conducted a mixture of experimental and numerical analysis to determine the damage constitutive constraints of the brain tissue by exploiting nonlinear optimization method. To do that‚ a mixture of the gray and white matters of the brain tissue were imaged using MRI and then the tractography approached was used to determine the angle of collagen fibers in them. Finally‚ the tissue samples were subjected

Biological level of analysis – serotonin Serotonin is a neurotransmitter which plays different roles in our brain‚ and can have effects such as sleep‚ arousal levels and emotion. The study was conducted by two researchers‚ Kasamatsu and Hirai‚ at Tokyo’s University in 1999. The aim of the study was to find out how the sensory deprivation affects the brain and later on‚ the human behavior. In order to achieve their aim‚ the researchers examined a group of Buddhist monks who went to a religious
