Primary auditory cortex

1. The pinna or auricle directs sound waves into the auditory canal. The eardrum vibrates according to frequency. Vibration transmitted to malleus then incus and then stapes of the middle ear. When the stapes vibrate, the membrane of the oval window is pushed in and out. This created the fluid pressure in the perilymph. Pressure waves enter the Scala vestibule then Scala tympani and then round window. This is where the walls become deformed in Scala vestibule and Scala tympani. Pressure…

observation, following children as they develop into adults to adequately mark the effects of music at birth. Additionally, the study of how the brain processes music is important, because music is used as a therapeutic based on how the brain responds to auditory stimulation. Primarily, this research paper will address the basic stages of brain development in children, and outstanding studies that help to delineate the areas of the brain responsible for conditioning and which affect cognition…

Overall, from examining the brain from a three-dimensional stand point, I have learned a plethora of information to help me better understand the different capabilities my own brain has. Beginning with the cerebrum, I learned that this area mostly controls posture, balance, and coordination primarily in already learned, physical skills. A great example for better understanding of this area would be learning a dance. At first, one will not be capable of having the proper posture with each move,…

Do we really use only 10% of our brain capacity to function in everyday life? It really depends on self opinion. Some of us may think we use more of our brain when we are working and some of us may think that when we are relaxing our brains are relaxing as well. There is no scientific theory behind how much we use of our brain. Most of us use our brains daily, to think, to react, to sense feelings, etc. You may be surprised on how much we use our brains each day. Its always active, axons are…

Motor function and motor control begin in the motor cortex of the brain. The primary motor cortex is associated with generation of a motor program. Premotor areas are involved in complicated motor functions, such as required changes in output forces or velocities, or motor response to visual or auditory input. Also, the basal ganglia and thalamus are important coordinating centers for goal­directed motor programs and patterns. The cerebellum allows for unimpeded movements of those motor programs…

(brainstem) to the top (cortex); from least complex to more complex. When the brain begins to develop it starts with the brainstem where it is found at the bottom of the skull and controls the heart rate, blood pressure, and body temperature. Next would be the midbrain which is found at the top of the brainstem and it controls motor activity, appetite, and sleep arousal responses. After the midbrain comes the limbic system it is found in the most inner, central portion of the brain or cortex.…

All my life, I’ve always wondered, why? Why do I stammer? Is it something wrong with me? I know that I was born that way because unlike many people, stammering didn’t only occur when I was stressed or in an unconformable situation. I stuttered every time I tried to speak. No matter how hard I tried to control my speech flow, I couldn’t help it. It was natural. My relatives tried to help me, to cure me fof my speech disorder but they failed. They didn’t have patience with me. They believed that…

Those who open attack on several innocent people are often questioned on their motive for the occasion. For instance, everyone remembers the Sandy Hook shootings, but the motive was not completely clear. This event in Newtown, Connecticut in 2012, was a such a gruesome thing to learn about. Adam Lanza, the killer, shot his own mother and then continued his shooting spree to at Sandy Hook Elementary School. News reports have noted that Adam Lanza was fascinated or “obsessed” with mass murderers…

Anatomy of cerebral cortex: Brain is most complex organ in human body. The ability of brain for its functioning normally is manifestation of various activities it takes participation in various activities of day to day life, being it hidden from the view or perceptible, like walking, smelling, thinking, laughing, speaking, and hearing. These manifestations are results of very coordinated and complex electrical and chemical activity within and between the cells those makes up our brain. Abnormal…

I need my brain to know when to move. When playing volleyball, I need to be able to move around in order to get to where the ball had been hit. In order to do this my brain uses neurons to transmit signals to my body that allows me to make quick motions. Sensory neurons send messages from my muscles and sensory organs, like my eyes and ears, to my brain and spinal cord. My brain then processes that message and sends a response back to my muscles via motor neurons. If, for instance, one of my…
