This can lead to multiple sclerosis. Next, dendrites are finger like receptors where the signals come from other neurons. Although the dendrites do not touch other neurons, they come close, leaving tiny gaps which called as synapses to separate them. An important function of the dendrite is the integration of various input signals.

The parietal lob is at the posterior of the frontal lobe. It is in the middle of the brain. Since the parietal lobe is in the middle of our brain it allows us to know signals for vision, hearing, and memory. The parietal lobe gives us feeling of pain, and a sense of touch and temperature. Although the parietal lobe isn’t as major as the frontal lobe, it’s still very important.

Environmental factors tend to modify the inputs received by the sensory pathway. The developing brain is most vulnerable to these alterations and interacts with the environment to modify its neural circuitry. In addition to other sensory stimuli, auditory stimulation can also act as external stimuli to provide enrichment during the perinatal period. There is evidence that suggests that enriched environment in the form of auditory stimulation can play a substantial role in modulating plasticity during the prenatal period.

The oscillations of the wave cause the medium surrounding it to oscillate along with it, allowing the sound to travel around the area. These waves produce sound which is capable of being deciphered by the human ear. This is because the sound being produced

Human sensory perception is facilitated by a number of extremely complex systems that are responsible for relaying sensory information to the brain. Two such systems are the visual system and the auditory system. The human visual system can be broken down into three major components: the retina, the visual pathway, and the visual cortex.197 Each of these three components house complex systems within themselves comprised of many small, yet significant, parts that work together to allow the processing of visual information.

The structures of the diencephalon comprise of:  Thalamus, which assists in sensory perception, regulation of motor functions as well as control of sleep and wake cycles.  Hypothalamus, which is the control centre for many autonomic functions during the release of hormones.  Epithalumus (the posterior area of the diencephalon that consist of the pineal gland), which helps in sense of smell and also helps to regulate sleep-wake cycles.  Subthalamus, which assists in motor

Accord-ing to the speaker. It is by translating vibrational energy coming from the ear through the ear fluid that these flappy organs convert physical motion into electrical motion and electrical signals. Hence, the role of sound receptors

INTRODUCTION: Voice articulation and language are the major elements of human speech production. When a disorder related to any of these elements is present, the ability to communicate may be impaired. Voice is the elements of the speech that provides the speaker with the vibratory signal upon which speech is carried. Regarded as magical and mystical in ancient times, today the production of voice is viewed as both powerful communication tools and a artistic medium.

Because it should be noted that the face expression and speech can intentionally influence to false emotion. For this reason it can be it can be helpful to use physiological signals like electroencephalogram (EEG) signal for study of human emotions. The emotions detected by EEG signals may be more advantageous because it is difficult to influence electrical brain activity intentionally. Moreover, the human brain is the origin of all the emotions and it is not possible to influence the brain activity

In this study, the stresses and deformations of the optic nerve at various IOPs were also calculated (Fig. 7b). The results illustrated that by increasing the IOP the stress in this component is amplified. The same pattern was observed in the resultant displacement of the optic nerve as a result of IOP increasing, since there was no dramatic alteration in the amount of displacement in the optic nerve head which can be lead to detachment from its site to sclera

When we hear a sound, the wave enters the ear canal and causes the eardrum to vibrate. The vibrations then passes through the middle ear which contains three bones that are connected. From there this gets fluid moving into the inner ear. This fluid maneuves through hair like cells which then turns those vibrations to nerve impulses. Those impulses are then moved to the brain bythe auditory nerve.

The medulla oblongata is located between the pons and spinal cord. This structure is responsible for basic vital life functions such as breathing, heartbeat, and blood pressure. The midbrain is involved in functions such as vision, hearing, eye movement, and body movement. The pons are involved in motor control and sensory analysis. For example, information from the ear first enters the brain in the pons.

Lighting: Light is crucial for the perception and recognition of color. It’s also necessary to have a colored surface from which light can be reflected into the eyes. The perception of color is influenced or altered by the change in the wavelengths of light contained in this reflected light and their relative power. Not all people can perceive colors, visually impaired people may not be able to perceive some or all colors, as well as some people who are not recognized as visually impaired but also cannot perceive them.

In the iconic movie "Bratz", one character was deaf. Yasmin, a character in the movie was a singer, and even though he could not hear her with his ears, he could hear and feel the vibrations from a speaker. Sound is conducted energy, just like waves. Whenever you speak, hum, step, or dance, energy is released from whatever or whoever made the sound. This is why you can tell who has spoken in a quiet room.
