Thalamus

function of the thalamus is relaying and integrating information to and from the cerebral cortex using the many nuclei that lie within it. [10] Another vital role of the thalamus is to maintain consciousness of the animal. [11] This would account for the reduced mental status of the Labrador in this case, as the fleshy matter was located here. The lateral geniculate nuclei (LGN) are ‘olive’ like in shape and are found either side in the posterior thalamus. They receive input via the optic tract, which is the link between the thalamus and the LGN. [12] The input comes from both eyes and projects information to the visual cortex in the occipital lobe. [2] The medial geniculate nucleus is also found in the thalamus. It is responsible for auditory pathways. It receives auditory signals from both ears and projects them to the primary auditory cortex. Having a tumorous mass around this structure could allow this relay of information to be disrupted and would explain the non-existent or aggressive response of the dog to its owner.…

in the posterior body of the corpus callosum thinning, the lateral ventricles becoming larger, and the lateral ventricular walls becoming irregular (Straub & Obrzut 2009). A second type of damage is bleeding of the brain caused by defective blood vessels; this is also known as intracranial hemorrhage (Straub & Obrzut 2009). In addition, cortical and subcortical damage along with multicystic encephalomalacia and other cortical lesions were found in patients with cerebral palsy (Bax, Tydeman, &…

ability to locate the issue in order to diagnose and subsequently treat it properly. Through research, this Brave New World can be brought to reality. Today, the world of medicine knows not the true pathway from the source of stimulus to the brain. The preliminary pathway has originally been described as follows: an impulse is sent from nerve cells in the skin, then passes to the lateral spinothalmic tract within the spinal cord; the impulse is then sent through to the medulla oblongata - a…

I am Thalamus according Scholapedia, am a small part of the brain located between in the middle and the center of the brain and I’m connected to the cerebral cortex and the midbrain thru nerves. I have many functions, but my main function is to regulate the voluntary motor control, the consciousness whether a person is asleep or awake (the sleep cycle), sight, sound, taste, and touch. I’m composed of 3 different groups of cells; the sensory relay cell or nuclei which receive sensation or…

down the spinal cord. The reticular formation travels through both the brainstem and the thalamus. The reticular formation is comprised of two parts, the ascending reticular formation and the descending formation. The ascending reticular formation which is responsible for awakening and falling asleep. It is also a mediator that regulates the level of awareness at any given time. “The descending reticular formation is involved in posture and equilibrium as well as autonomic nervous system…

The Limbic system is a critical part in the brain that makes a human feel emotions. It links us to a primitive state and higher thinking. The Limbic system is composed of numerous structures within the brain. There is not a certain structure that is defined as the Limbic system. The Thalamus, Hypothalamus, Amygdala, the Hippocampus, and the cingulate cortex are the framework for the limbic system. Its location is in the Forebrain and the Midbrain just under the cerebrum. All the structures work…

This summary consists of the experience and results obtained by different scientists after manipulating the brains of people, to control and monitor the thalamus, and other parts of the brain. These experiments allow the scientists involved in the study to study the effect of deep brain stimulation and the effect that is has on sleep. For instance, deep brain stimulation abbreviates (DBS). The stimulation consists of performing different surgeries on patients that had experienced tremors with no…

The human brain is very fascinating. It has many parts and functions, which help us in our daily lives. The brain is one of the most important things we humans have. The human brain has four parts: Hindbrain, Midbrain, Forebrain, and Cerebral Cortex. With each part comes its functions. For hindbrain the parts are medulla, cerebellum, and pons. For forebrain the functions are the limbic system, thalamus, hypothalamus, basal ganglia, and cerebral cortex. And last the cerebral cortex, the sections…

had an easier time writing this essay. My question was answered and I now have a better idea of how the brain works, why the brain is so important and all the function of the brain parts. Overall, I think writing this was a great learning experience for me and I gained much knowledge from it.  Bibliography "3 Main Parts of the Brain." Alzheimer's Association. N.p., n.d.

One of the major channels of the spinal cord is the spinothalamic tract; a sensory pathway. It conveys nerve impulses for sensing pain, warmth, coolness, itching, tickling, deep pressure, and crude touch. (Tortora, 2014-01-22, p. 461). Based on that description and as the name implies, information will travel from the region of stimulation on the skin to the CNS, ultimately landing at its destination at the thalamus; thus, making it an ascending pathway. This pathway is further divided into…
