     A cochlear implant is an electronic device that restores hearing for people anywhere from hard of hearing to the profoundly deaf. The cochlear implant is surgically implanted under the skin behind the ear. The surgeon puts the electrode array inside the inner ear and than inside the cochlea. The implant works by a device outside the ear, which rests on the skin behind the ear. It is held upright by a magnet and is also connected by a lead to a sound professor.

Sounds and speech are captured by a microphone and sent to the external speech processor. The processor then translates the sounds into electrical signals, which are then sent to the transmitting coil. These codes travel up a cable to the headpiece and are transmitted across the skin through radio waves to the implanted cochlea electrodes. The electrodes’ signals then stimulate the auditory nerve fibres to send information to the brain where it is interpreted as meaningful sound.

Located in the inner ear, the cochlea is small, but packs a mighty punch. The cochlea plays an important role, as it takes the sound vibrations that it receives and transforms them into nerve impulses. These nerve impulses are then sent to the brain, where they are translated into recognizable sounds. The cochlea is truly amazing, as it helps us perceive the sense that we refer to as “hearing”. In fact, the cochlea is considered to be the most complex part of the ear! Learn more about this amazing organ with these amazing cochlea facts.

Through our understanding of the structure and function of the Ear in the human body, scientists have been able to invent such development to support the human sense of hearing for the world. This development has made a huge impact since 1978. The cochlear implant is a small, biomedical device which comprises of a microphone, a speech processor, receiver and electrode component. The

The purpose of the cochlear implant is to help replaces the damaged function of the inner ear, the cochlear work in any damaged parts and will provide sound signal to the brain (Cochlear Ltd, 2017).

The purpose of the cochlear implant is to bypass the damaged hair cells in a patient’s cochlea and help establish sounds. The product uses a microphone which is situated on the exterior of the ear. The microphone and electricity

A cochlea implant is a bionic hearing system. It is a surgically implanted device that helps you hear and perceive sound. If the important parts of the cochlea aren’t working properly that means that the hear nerve is not being simulated properly. That means that there is no possible way that the electrical signals are being transmitted to your brain thus causing you to hear. With a cochlea implant, they put a microphone onto the implant. The sound travels through an external mini-computer called a sound processor. The sound is processed and turned into digital information. The information is sent over a transmitter antenna to the surgically implanted part if the system. The implant turns the sound information into electrical signals; they

The brain the most complex, three-pound organ in the human body. When I think of the brain it reminds me of a committee of professions working together to achieve one goal each with individual tasks to get the job done. The brain can be divided into the basic parts and two hemispheres: The forebrain, the midbrain and the hindbrain, the right hemisphere and the left hemisphere. The two hemispheres are then connected by the corpus callosum. the cerebrum is covered by a thin layer of gray tissue called the cerebral cortex. The cerebral cortex is in turn divided into four lobes: frontal lobes, parietal lobes, temporal lobes, and occipital lobes. The cerebrum or telencephalon.

CNS. The CNS acts as the control center of the body by providing its processing, memory,

Perceptual set is another factor that can effect visual perception. Perceptual set is a predisposition to perceive stimuli in a specific way;

The brain which is principally the main organ of the nervous system, is the center of all mental activity. These activities include thought, learning, and memory. It is also the most complex and delicate organ within the body. Within the brain are four major regions which are the brainstem, cerebellum, diencephalon, and cerebrum.

A cochlear implant uses an electronic device that is surgically implanted within your ear, particularly its canal. It is performed if you suffer from severe or worsening hearing loss. Essentially, the implant replaces the function of your inner ear’s hair cells, which help you register sound vibrations and when damaged, are not able to function. While a cochlear implant will not give you back 100% of your hearing ability, it is enough to allow you to hear and understand most sounds and communicate better with other people.

Our world is an immensely vast place. It is a place in which great clockworks of life govern everything from the largest interdependent “network” to the smallest details. As humans, we have evolved to perceive the world primarily through visual stimuli. In terms of intricacy and the area of the brain dedicated, our visual sense is the most well-developed sensory system. Our eyes are adapted so that they focus on objects both near and far through the contraction and relaxation of the ciliary muscle (Kaufman, Levin, Alm). However, we cannot focus on everything at the same time. This process of focus is selective as we can pay attention to and process only so much information at once (Chen, Choi). As a result, humans are able to process some visual stimuli but may completely fail to regard other details, be they minute or monumental. This failure is described as “inattentional blindness”, and it can have several real-world implications in our everyday lives.
