The Sense of Smell: A Powerful Sense The olfactory bulb is one of the structures of the limbic system and a very ancient part of the brain. As mentioned in the previous description of the olfactory process, the information captured by the sense of smell goes from the olfactory bulb to other structures of the limbic system.The limbic system is a network of connected structures near the middle of the brain linked within the central nervous system. The olfactory bulbs has sensory receptors that are actually part of the brain which send messages directly to: 2  The most primitive brain centers where they influence emotions and memories (limbic system structures), and. “ 3 Higher” centers where they modify conscious thought (neo-cortex).

14. Olfaction and the Limbic System Olfactory bulb and tract: Neurons in the olfactory bulb (#4965) called mitral cells are secondary sensory neurons of the olfactory system. Their axons leave the olfactory bulb and enter the olfactory tract (#4963). The olfactory tract is not a peripheral nerve. It is part of the central nervous system.

What senses does the thalamus control? The thalamus, which is in charge of sensory perception and the  regulation of motor functions, receives signals from almost all  senses. The only exception to this is the se … nse of smell.ll of our senses except for our sense of smell. They are controlled by a separate station, the olfactory bulb, which explains why certains smells seem to do such a good job at bringing back certain memories.

India A bit of a joke - but senses (including your sense of smell) are very important. Your senses let you know what is going on in the world around you. Humans have five senses: hearing, sight, smell, touch and taste. They are controlled by five sense organs: the ears, eyes, nose, skin and tongue. The ears, eyes, nose, tongue and skin are the five sense organs. Click on the pictures to find out more about each human sense! Animals rely on some senses more than others. Hunting animals, like the cheetah, need very good eyesight to find their prey. Nocturnal animals often have very large eyes to maximise the amount they see at night, but also rely heavily on their sense of hearing. We understand the five human senses, but did you know that some animals can use different senses to find their way around in the world? Read on to find out more! The platypus has very poor eyesight.

The Sense of Smell: A Powerful Sense The olfactory bulb is one of the structures of the limbic system and a very ancient part of the brain. As mentioned in the previous description of the olfactory process, the information captured by the sense of smell goes from the olfactory bulb to other structures of the limbic system.he sense of smell is a strong sense for identification purposes and can have a strong impact in your brain because it is such an integral part of it (to the point that strong chemical smells can definitely elicit seizures).

Olfactory bulb As a neural circuit, the olfactory bulb has one source of sensory input (axons from olfactory receptor neurons of the olfactory epithelium), and one output (mitral cell axons).As a result, it is generally assumed that it functions as a filter, as opposed to an associative circuit that has many inputs and many outputs.he accessory olfactory bulb (AOB), which resides on the dorsal-posterior region of the main olfactory bulb, forms a parallel pathway independent from the main olfactory bulb.

- The olfactory nerve (a cranial nerve-therefore located in the cranium of the brain), then passes the message to the olfactory bulb, which is the inferior (bottom) part of the brain. This section of the brain can discriminate between different odors and arouse higher areas of the brain based on the odor that it detects.

How Smell Works A smell can bring on a flood of memories, influence people's moods and even affect their work performance. Because the olfactory bulb is part of the brain's limbic system, an area so closely associated with memory and feeling it's sometimes called the emotional brain, smell can call up memories and powerful responses almost instantaneously.

NERVOUS SYSTEM III: SPECIAL SENSES Olfaction or the sense of smell involves chemicals. The receptors for smell are the olfactory hair cells located on the roof of each nasal cavity in a path of cells called the olfactory epithelium or membrane. Odors or scents chemical vapors. Chemoreceptor cells (neurons) perceive the chemicals as they vaporize. Olfactory receptors in the nose: chemoreceptors. - Taste receptors on the tongue: chemoreceptors. - Skin receptors: tactile, mechano, thermo, nociceptors. 2. Visceroreceptors: sensory receptors that produce sensations from organs or internal tissues. - Sensations include pain, hunger, thirst, fatigue or nausea.

Sensory receptors This specificity arises from the sensory endings that are used by each system. Again in the visual system the photoreceptors are designed to trap and respond to photons of light. The olfactory system contains receptors designed to respond to single or limited numbers of chemical odorants.

- Normally, there are brain cells (neurons) in the human brain that produce dopamine. These neurons concentrate in a particular area of the brain, called the substantia nigra. Dopamine is a chemical that relays messages between the substantia nigra and other parts of the brain to control movements of the human body.his process of impairment of brain cells is called neurodegeneration. The current theory (so-called Braak's hypothesis) is that the earliest signs of Parkinson's are found in the enteric nervous system, the medulla and in particular, the olfactory bulb, which controls your sense of smell.

Action potential (February 2011). The olfactory system is the sensory system used for olfaction, or the sense of smell. Most mammals and reptiles have two distinct parts to their olfactory system: a main olfactory system and an accessory olfactory system.he olfactory nerve, similar to the optic nerve, is not part of the peripheral nervous system but is defined as a part of the brain. This nerve terminates in the olfactory bulb, which also belongs to the central nervous system.

Olfactory EpitheliumTissues (February 2011). The olfactory system is the sensory system used for olfaction, or the sense of smell. Most mammals and reptiles have two distinct parts to their olfactory system: a main olfactory system and an accessory olfactory system. The main olfactory system detects volatile, airborne substances, while the accessory olfactory system senses fluid-phase stimuli.

MODULE 4Other Senses The olfactory (smell) receptors and the olfactory bulb are located deep in the nasal passages. The olfactory receptors lie in two small patches on the roof of each nasal passage. Figure 14 shows a cross section of the nose. The receptors are stimulated by specific molecules, which initiate impulses to the brain.
