Wernicke's & Broca's Aphasia

Aphasia
        Wernicke's Aphasia is a language deficiency that is the cause of left-hemisphere damage.  The area of the brain where this occurs is within the left inferior cortex.  An individual with this deficiency does not have a problem with getting the words out, as in they don't stutter, but the words have a fluidity to them. The individual is able to say words, but these words don't have any meaning. These individuals understand the dimensions of the conversation, and even though the words lack any concrete meaning, the individual doesn't get frustrated with them-self.  Their words can be thought of as a "word salad". Also, they are unable to understand verbal speech or even sign language, which can be a comprehension issue. This type of Aphasia has a relatively normal or fluid production of words, but these words come out as jibberish.  Therefore these individuals have a difficultly of actually comprehending the language or the content (of the conversation).

        Broca's Aphasia is a language deficiency that is also the cause of left-hemisphere damage, which is often thought of as a stroke.  Broca's Area is located in the left inferior frontal cortex.  People with this disorder struggle to get the words out and because of this, they often become frustrated with themselves.  They do not have any difficulties with comprehension, but they may often stutter to try to get the correct words or sounds out.  It is a motor problem with trying to get the words outs properly, which is linked to functions in the frontal lobe.  Even though people with this type of aphasia have a difficulty to produce words, the words still makes sense; there is comprehension of what is being asked.

       Hope you enjoyed this introduction into two vary famous types of aphasia! This language dysfunction is often cause my damage to the brain and isn't just something that happens when you wake up one morning. It affects, according to the link below, "....80,000 individuals acquire aphasia each year from strokes. About one million people in the United States currently have aphasia."

Intro of Psych Knowledge and the Lobes of the Brain

Hello everyone!
     This blog will be written about my knowledge of Psychology. The reason for choosing this particular topic is because it is something that I am familiar with and it is something that I am studying. There has been so much research done to prove a particular finding, but there is a vast ocean of  knowledge that has not been found out. Psychologists are familiar with the lobes of the brain and the basic functions that that each part does, but the details of every single one of those parts is still unknown. So let's start with something easy, like the four lobes of the brain.
     The four parts of the brain are the Frontal Lobe, Parietal Lobe, Occipital Lobe, and Temporal Lobe. The Frontal Lobe is located right above your eyes and is responsible for the planning of movements, some aspects of memory and the inhibition of inappropriate behaviors. The Parietal Lobe is located behind the Frontal Lobe. It is responsible for integrating sensory information from different parts of the body, the notions of numbers and their function, manipulation of objects, and there are some aspects of vision.  The Occipital Lobe is located in the back of the brain and is responsible for vision processing and can be linked to the origination of  dreams. The fourth lobe is called the Temporal Lobe and is located where the temples are, which is below the Frontal and Parietal Lobe. Its function is auditory perception, advanced visual processing, and is a key to the formation of long-term memory.
      That is just some basics about the brain and what the functions of the four lobes of the brain. If you have any questions, please don't hesitate to ask. Hope you enjoyed the Psych Knowledge!
