The diencephalon, alongside the cerebrum make up the two major divisions of the forebrain. The main structures of the diencephalon include the hypothalamus, thalamus, epithalamus (including the pineal gland), and also the subthalamus. Moreover, located within the diencephalon is found the third ventricle, which is one of the four brain ventricles or cavities filled with cerebrospinal fluid. The function of the diencephalon is to relay sensory information between brain regions and control many autonomic functions of the peripheral nervous system. Furthermore, it connects structures of the endocrine system with the nervous system and works in together with limbic system structures so as to generate and manage emotions and memories.
The auditory nerve, much like the optic nerve of the visual system is composed of ganglion cell fibers. In the case of the auditory system, these fibers originate from ganglion cells in the spiral of the cochlea.112 The fibers of the auditory nerve carry signals to the brainstem where they then synapse with neurons within the cochlear nucleus. Information from the left ear is transmitted to the left cochlear nucleus and information from the right ear to the right nucleus, however, much like in the visual system, many of the fibers that leave the cochlear nucleus cross over to deliver signals to the contralateral side of the brain.112 The area of the brainstem that is believed to process information about where sounds are coming from, the superior olive to be exact, receives input from fibers on both sides of the nucleus.112 The auditory system differs from the visual system in that in the auditory system, the cochlea is unable to produce an exact placement of the location of a stimulus, whereas the retina, within the visual system, can directly identify where a stimulus originates.114 This, again, is where the superior olive comes into play computing very small time differences between the signals that arrive in each of the
1.Spinal cord - is a long, and tubular shaped structure that contains nervous tissue and cells located at the end of the brainstem and continues down to the bottom of the vertebral column. It used to connect the peripheral nervous system and the brain. It acts as sensory system and transmitted message to the brain. 2.Conus medullaris - is a tapered structure that located in the most distal part of the spinal cord and end with filum terminale. 3.Cauda equina - It makes of spinal nerves and spinal nerve root that located near the first lumbar vertebra of spinal cord.
These molecules are found throughout the body, namely in areas such as the brain, the organs, immune cells, glands and connective tissues. In each tissue, the endocannabinoid system performs different tasks but the overall aim is the same. This is that of homeostasis (TruthOnPot.com, 2013). Homeostasis is the control of a stable internal environment. The endocannabinoid system is a unique system in the brain that affects important functions such how a person feels, moves and reacts (The Science of the Endocannabinoid System, 2011).
The sympathetic fibers project and synapse in the sympathetic cell column from vertebrae C8 to T2. This cell column is called the ciliospinal center of Budge. Once the fibers exit the spinal cord, they travel through the stellate ganglion, the inferior cervical ganglion, and the middle cervical ganglion to synapse in the superior cervical ganglion at the carotid artery bifurcation. From the bifurcation the fibers travel with the internal carotid artery, and then enter the cavernous sinus. From the cavernous sinus they travel along the abducens nerve.
Most of the action that happens in the brain that is related to sleep is in the hypothalamus, which is located in the Limbic System next to the temporal lobe. The Limbic System is the part of the brain that works with emotions and motives through a network of neural structures; it consists of the hypothalamus, the pituitary
The Mudra therapy is a very unique concept and it deals with the stimulations of the nerves in the hand and the brain. The nerves play a very major role in the concept of Mudra therapy. The nerves in the hand get stimulated on holding a particular hasta mudra; they travel via the spinal cord and reach the brain. The brain gets stimulated and sends impulses to the respective parts of the body, depending on the fingers involved in holding the hasta mudra, as each finger in the hand corresponds to a particular part in the body. Hence the knowledge of the nervous system of the hand is required to understand the therapeutic effect of the hasta mudras effectively.
“Protected within the skull, the brain is composed of mostly of the cerebrum, cerebellum, and brainstem.” (“Anatomy of the Brain, mayfieldclinic.com”) The cerebrum is the biggest part in the human brain, and is divided into lobes including the frontal lobe, parietal lobe, occipital lobe, and temporal lobe. Each lobe has its own tasks. For example, “the frontal lobe is associated with reasoning, planning, parts of speech, movement, emotions, and problem solving, the parietal lobe is associated with movement,
They have the ability to transmit the signals among the nerve cells. They had known as neurons. Also, communicate the information throughout the body and brain. The brain utilizes neurotransmitters to inform the lungs, heart and stomach to do their functions. Those like, lungs to breath, heart to beat and stomach to digest.
Introduction Brain to Brain Interface (BBI) has been made likely as the way brain cells interact with each other. A process is known as synaptic transmission in which cell to cell communication occurs, chemical signals passing among cells ensuing electrical spikes in the other or the receiving cell. Synaptic transmission formulates the base of all brain activity, these activities are motor control, memory, observation, and emotion. Since cells are linked together in a network, brain activity produces a harmonized pulse of electrical activity, which is called a brainwave. Changing in the brain waves conferring to the perceptive procedures that the brain at the present time is working through and are characterized by the time-frequency outline of the up and down states or oscillations.
