Perception is the mental process by which our brain organizes and interprets sensory information, transforming it into meaningful objects and events. the optic nerve leaves the eye. Rods and cones are the eyes receptor cells.
The interpretation of sensory information is called perception. During the receiving any information, how one attach meaning for that sensory input is the central question of the perception studies. The perception studies can be subdivided into visual, auditory, touch, olfactory and touch perceptions.
A stimulus reaches a physiological threshold when it is strong enough to excite sensory receptors and send nerve impulses to the brain: this is an absolute threshold. A message below that threshold is said to be subliminal: we receive it, but we are not consciously aware of it.
Sensory adaptation, selective attention, and signal detection theory can help explain what is perceived and what is not. In addition, our perceptions are affected by a number of factors, including beliefs, values, prejudices, culture, and life experiences.
What is the difference between sensation and perception? Sensation is the process by which our sensory receptors and nervous system receive stimulus energies, whereas perception is the process by which the brain organizes and interprets these stimulus energies.
Neural activity created by this stimulation passes to the primary olfactory cortex at the back of the underside, or orbital, part of the frontal lobe. Olfactory information then passes to adjacent parts of the orbital cortex, where the combination of odor and taste information helps create the perception of flavor.
Olfactory system, the bodily structures that serve the sense of smell. The system consists of the nose and the nasal cavities, which in their upper parts support the olfactory mucous membrane for the perception of smell and in their lower parts act as respiratory passages.
Your sense of smell—like your sense of taste—is part of your chemosensory system, or the chemical senses. Your ability to smell comes from specialized sensory cells, called olfactory sensory neurons, which are found in a small patch of tissue high inside the nose. These cells connect directly to the brain.

Smell
The smell is considered the primitive sense and can be called the weakest sense. The visual sense affects almost sixty percent of the brain and can be called the strongest sense.
Studies have found that newborns have a strong sense of smell. Newborns prefer the smell of their own mother, especially her breastmilk.
The human infant is able to detect the smell of his or her mother’s breast without the experience of consuming it during the first days of life. 8, 9 Infants who consume their mothers’ milk (from 4 days to 15 days after the birth) prefer the smell of their mothers’ breast milk to that of other nursing mothers.
Research shows that a baby’s health can improve when they sleep close to parents. In fact, babies that sleep with parents have more regular heartbeats and breathing. They even sleep more soundly. And being close to parents is even shown to reduce the risk of SIDS.
