Question

In your discussion, explain the brain mechanism associated with vision, hearing, taste, smell, or body sense. b) discuss something that you found interesting within the mechanisms and explain why.

Answer 1

The stimulus of each sense organ related to the different parts of the brain through different pathway or nerve system.

Sensory information transmitted peripheral nervous system to central nervous system.

the brain mechanism associated with vision:
visual information processing happened in the visual cortex of the occipital lobe in brain.The ability of the eyes to make out the image of the visible light.there are two kinds of photoreceptor which is called as cones and rods can used to detect the image of the light which create action potential or nerve impulses which sent to the brain via optic nerve in the eye.Cone can used to detect colour and rod can used to detect sensitive of light.

the brain mechanism associated with smell:

Sense of smell are process in olfactory cortex of the temporal lobe in the brain.
olfactory cortex can used to recive signals from olafactory bulb for indetify the odor.
the sense of smell also called as olafaction which is more related to taste sensory.
fragrance or smell in the air sensed by olfactory receptors in the nose.these smell sense directly sent to olfactory cortex of the brain via olfactory bulb.

the brain mechanism associated with Taste:

Sense of taste processed in the gustatory cortex in the partial lobe of the brain.
The sense of taste anoter name is gustation.
the sense of taste can used to findout the chemicals in food, minearl, vitamins, poisons and so on.
mainly 5 five types of taste rely on brain.
they are
1.sweets
2. bitter
3. umami
4.salty
5. sour

these kind of taste detected by taste buds of the tongue.

the brain mechanism associated with hearing:
Sense od sound is processed in auditory cortex of temporal lobe in the brain nerve system.
sense of hearing also called as audition in the sound form.
sound is make out by ear through mechanoreceptors.
the sound signals directly travel to through
the brain via auditory nerve
human sound hearing value is 20- 20,000 Hz

b) discuss something that you found interesting within the mechanisms and explain why.

human brain feel no pain even in your body any part suffering in pain.

brain weight is just 2% of human body but it consumes more amount of energy value is 25 Watt which can used to illuminate light

More than 100 billions of neuron present in human brain

human using maximum less than 10% of their brain(bitter truth)
