Influence Genes Have On Behavior Essay

The Broca speech area is rostral to the inferior edge of the premotor area on the inferior frontal gyrus. It is usually on the left hemisphere and is responsible for the motor aspects of speech. Damage to this area leads to expressive aphasia or dysphasia (p.452)

22. The part of the lower brain located behind the pons that controls and coordinates involuntary, rapid, fine motor movement is called the cerebellum.

The Frontal lobe; which is to do with behaviour, the person’s personality, interpretation and feelings.

First, the part of the brain that is responsible for higher forms of thought such as language, the broca’s area which pertains to the production of speech, located in the frontal lobe, is much needed for communication with my friends. When I first seen my friends it was the broca’s area that allowed me to speak smoothly and fluently to them, and as we sat around the table together eating pizza and playing cards it was this part of the brain that indorsed my friends and I to socialize as it helps everyone talk to one another. The Wernicke’s area that is affiliated with the broca’s area is the part of the brain that helps understand the meaning of words.

The areas of Michael's brain that were injured during his birth affected his control over his voluntary movements. Which part of the nervous system distributes motor commands to skeletal muscles?

1b. List and describe briefly the major structures of the brain, as presented in your textbook, including the function of those elements that are most related to psychoactive drug reaction.

2. Think about whether or not everyone 's synapses develop the same because of genetics (nature) or the environment (nurture). Please explain the role that genetics (nature) and the environment (nurture) play in the development of the six (6) major components of the synapse. Do this by listing and providing a brief summary of the six (6) major components. Then, describe how genetics (nature) and the environment (nurture) might affect the development of the six (6) major components as a whole.

b.) What is the role of cortical brain regions (i.e., cerebellum, the anterior cingulate cortex, the supplementary motor area, and the right frontal operculum)

b. This affects the visual processing reaction time causing the driver to drive much slower, keeping a distance between vehicles and checking their mirrors and blind spots (Aker, 2011).

Scott (2000) suggests that closed head injury happens due to accident. When the skull has been knocked by a hard surface, the brain is twisted pushed against the skull which resulted contusion and damage to the frontal part of the left side of the brain which is dominant for language. Scott also emphasizes that the skull may be fractured due to the hit but the tissue coverings are unimpaired and there is no penetration of the skull. Nevertheless, patients with closed head injury will not be able to produce speech due to the damage. Therefore, their impairment can be considered as Broca’s aphasia. On the other hand, the other cause that can lead to Broca’s aphasia is open head injury. This injury is more severe than the closed head injury. Kaur and Wolff (2012) report that open head injury may cause diffusion of the skull because the shape of the skull is badly damaged and the tissue beneath it is completely destroyed. As a result, injured patient produces halting speeches which can be considered as Broca’s aphasia.

Similarly to Broca, in his studies, Wernicke encountered patients with brain lesions, however, these lesions were located on the posterior areas of the left temporal lobe. Also, while patients could speak, their words were often unrecognizable. This portion of the brain was identified to be responsible for understanding language

Aphasia is a language disorder that can be the result of a brain injury. An individual that is suffering from aphasia may experience difficulty speaking, writing, reading, or comprehending. There are three different types of Aphasia that differ in various ways. First, Wernicke’s Aphasia is the inability to grasp the meaning of words and sentences that have been produced by another individual. This type of aphasia is also known as “fluent aphasia” or “receptive aphasia”. Wernicke patients’ speech may come across like a jumble of words or jargon, but it is very well articulated and they have no issue producing their own connected speech. If the patient is consecutively making errors, it is common for them to be unaware of their difficulties, and not realize that their sentences don’t make sense. The severity of the disorder varies depending on the patient, and the disorder results form damage in the left posterior temporal region of the brain, which is also known as Wernicke’s area.

The parietal lobe is responsible for our motor co-ordination; motor impulses to the muscles are

Broca’s area is located in the frontal lobe of the left hemisphere. It’s involved in the production of coherent speech, it moves the needed muscles that are required for speaking.

The purpose of this paper is to pursue one important and fundamental aim: language and the brain are purely inseparable since it allows us to perform essential tasks such as generating, comprehending and expressing speech. With damage to the brain, individuals can no longer perform such tasks which can ultimately lead to many types of language disorders. The focus of this paper is Broca’s aphasia, a language disorder characterized by the inability to produce written and spoken speech. Damage to the brain can cause many types of speech impairments as well as comprehension deficits.
