The olfactory lobe, or olfactory bulb, is the structure within the brain that receives neural input from the nasal cavity, thus processing the sense of smell, according to Encyclopedia Britannica. The nasal cavity's smell receptors are connected to the olfactory bulb through axons.Know More
The olfactory bulb is located in the front section of the brain in many animals, but in humans it is located in the bottom portion. The cells within the nasal cavity detect odors in the form of chemical particulates within the air and send the received information to the olfactory bulb. The olfactory bulb is believed to tell odors apart, amplify sensitivity to odors, identify important odors and send the information to higher level areas of the brain for further information processing, according to Wikipedia. While, from its structure, it appears that the olfactory bulb could exclusively perform all of these tasks, scientists are unsure whether it is the sole structure within the brain that performs these functions.
The olfactory bulb is comprised of five layers: the granule cell layer, the internal plexiform layer, the mitral cell layer, the external plexiform layer and the glomerular layer. These layers are listed in order from internal to external, and each perform specific tasks related to the neural processing of odors, according to Wikipedia,Learn more about Organs
The cerebrum plays a role in many of the body's major functions, including determining personality and intelligence, understanding and producing language, interpreting sensory input, organizing, planning and overseeing motor functions. Also called the telencephalon, the cerebrum makes up about 70 percent of the mass of the brain, covering most of the brain's other structures. The cerebrum's outer portion has a covering of gray tissue known as the cerebral cortex, and it is split into left and right hemispheres joined at the corpus callosum.Full Answer >
Neuroscientists suggest that the brain is always firing or using its cells, the neurons, to perform functions. Over the course of a normal day, most people use all of their brain capacity. Previous myths stated that humans only used 10 percent of their brains.Full Answer >
Monitoring and controlling all other functions of the body, the brain is one of the most important organs of the body, states About.com. It is comprised of three main parts: the forebrain, the brainstem and the hindbrain.Full Answer >
The medulla oblongata is the part of the brain that controls functions like blood pressure, heart rate, reflexes and vomiting. In essence, it controls all the body's involuntary reflexes.Full Answer >
