This week we are discussing our senses. Identify at least 3 senses and include the brain areas involved for each sense. Consider whether there are more than five senses and provide examples of additional senses. Include the role sensation and perception play as they apply to human sensory process. Use clear examples. Expected word-count for substantive participation is between 175-275 words. Add at least 1 reference, edit for grammar/spelling, and check for plagiarism. It is encouraged to bring in outside supplemental resources for review (please use a reputable internet site).

Respond to the 2 following response to the question above with a minimum of 75

Number 1: The senses I chose for this discussion are sight, hearing, and smell. I found these known senses interesting and complex at the same time. Sight or vision is interesting to me because it involves the eyes which are a sensory organ. The eyes are used to pick up on the changes in our environment. Neurons help sensory organs such as the eyes to detect things physically. Sight is basically images being focused on the retina. This causes messages to be sent to the brain through the optic nerve to the thalamaus, the primary visual cortex, and the striate cortex. Hearing is another sense that I found interesting. Hearing is being able to pick up on pitch, loudness, and timbre (Carlson, 2013, p. 213). Auditory information is sent to the brain through the conchlear nerve, the medulla, the dorsal midbrain, and the thalamus. From there, it goes to the auditory cortex of the temporal lobe (Carlson, 2013, p. 214). The sense of smell or olfaction is another sense I found interesting. Smelling is our ability to detect changes in odors in our environments. The areas in the brain associated with the sense of smell include: the amygdala, hypothalamus, the orbitalfrontal cortex, and the dorsomedial nucleus of the thalamus.

Examples of other senses include: thermoception (temperature), balance, and nociception (pain). Perception and sensation play an important role in the human sensory process. Sensation is basically the way our senses gather information from outside stimuli. When our sensory organs take in a smell, see something, or hear a sound our brains pick up on them. Perception is the way we organize those sensations.

Number 2: There are a total of 5 senses that are recognized scientifically, and those are sight, touch, hearing, smell, and taste. Sight is seen through the eyes, which is connected to the brain. The information is passed through the eyes to the optical nerve and then to the occipital lobe. With hearing, the brain is very important, because it sends sound waves from the outer ear to the middle ear and then into the inner ear. This is when the vibrations excite the hair cells. Lastly, your sense of smell is part of the piriform cortex. This is located behind the olfactory bulb and helps identify the smells. These smells also go through the thalamus which is like a hub station for all the sensory information your brain is collecting. Additionally, there are more than five senses. The other senses are audition, vestibular senses, the somatosenses, gustation, and olfaction. Vestibular is located in the inner ear and associated with our movement and balance, Somatosenses is associated with touch, but include itching, tickling, pain, temperate, and vibration. Another sense is gustation which is how use our perception of taste, as well as flavor.
