The Brain Brittany Wagner Psy/240 June 22‚ 2014 Jennifer Graves The Brain The brain is like a hard drive for a computer. Like a hard drive the brain also has many wires and complicated looking things in there. It is a lot easier to understand what part of the brain does what when it is broken down into the five major parts. The brain has five major parts and each part helps the human body function. The five major parts are called the myelencephalon‚ metencephalon‚ mesencephalon‚ diencephalon

Inside the womb we start out as an egg‚ but one of the first major structures that begin to form is the brain. The brain itself is a complex structure that leaves much to be learned from it. It controls a person’s entire body function and movements whether it be walking‚ talking‚ or even going to the bathroom. What most people do not know is that there are five major structures of the brain. The first of the five is the myelencephalon ( the Medulla). The Myelencephalon (or medulla) is the posterior

The defining features of drug intoxication and addiction can be traced to disruptions in cell-to-cell signaling. October 01‚ 2007 Carl Sherman‚ NIDA Notes Contributing Writer illustration of a neuron Drugs of abuse alter the way people think‚ feel‚ and behave by disrupting neurotransmission‚ the process of communication between brain cells. Over the past few decades‚ studies have established that drug dependence and addiction are features of an organic brain disease caused by drugs’ cumulative

allows the synapse to pass information. Axon – It’s a long slender part of the nerve cell‚ that helps transmit the neural signal. Neurotransmitter – They are brain chemicals that communicate throughout the body. Amygdala – It is located in the cerebral hemisphere that looks like a grey almond shape‚ it controls the emotions we have from hormones‚ arousal and emotional memories. Hippocampus – This is in the medial temporal lobe it’s a small organ and is very important to the limbic system‚ it

various studies over sign language users. In case of spoken language users‚ auditory speech processing activates right hemisphere. With bilinguals it was believed that all the languages (more than two languages also) are localized in the same cerebral areas. But this had a controversy. It is proved by some experiments that brain areas recruited for L1 (primary language or the mother tongue) learning and processing are different from those recruited for L2 (second language acquired).

Alzheimer’s brain. There was a loss of nerve cells from the Cerebral Cortex in the Alzheimer’s victim. Approximately ten percent of the neurons in this region were lost. But a ten percent loss is relatively minor‚ and cannot account for the severe impairment suffered by Alzheimer’s victims. Neurofibrillary Tangles are also found in the brains of Alzheimer’s victims. They are found within the cell bodies of nerve cells in the cerebral cortex‚ and take on the structure of a paired helix. Other diseases

Journey of the brain-Birth to late adulthood Child development is crucial throughout the early years‚ during this time the development of the brain occurs and continues through late adulthood. The development of the brain contributes to the functioning of the body. The anatomy of the brain is made up of neurons and divided into four different lobes. The temporal‚ frontal‚ parietal‚ and occipital lobes control a variety of cognitive functions (Santrock‚ 2013). The
