Thalamus

ChanMee Bae Psych 421 Take-Home Exam Total 40 points with 2 One-Point Extra Credit 1. Where are the soma of the receptor cells for the sensation located? (1pt) Dorsal root ganglion of the spinal cord. (Students should state the spinal cord to get the point) 2. The pain receptors are called “nociceptors”, named one of the subtype of the nociceptors, and what are the one of four differences in those receptors? (2pts) 1) Mechanical. Thermal. or Polymodal. 2) Morphology of the peripheral ending.…

The optic nerve carries the visual stimuli to the thalamus, where it is sorted and sent to the correct place in the brain for interpretation. The thalamus is in the forebrain at the top of the brain stem, and it is from there that the information is transferred to the visual cortex in the occipital love at the back of the brain. Light travels in a straight…

system involves three central components; forebrain, brainstem, and hindbrain. Duties of the forebrain vary in functions including; receiving, processing sensory, intelligence, perceiving, and understanding language. The forebrain structures thalamus and hypothalamus are amenable for the functions of: sensory information, automatic…

pain. In the previous paper, the journey from the nerves, to the spinal cord, and lastly to the brain was discussed. Information was sent through a multitude of action potentials from the afferent neuron to the 2nd-order neuron to the thalamus. Once it got to the thalamus, the information was transmitted through the cortexes of the brain, leading to pain perception. The tricky part can be when the signal does not go through, we don’t feel any pain at all. This is possible for…

attentional processes. Attention and emotion are correlated this way. Emotional processing studies recently began considering the pulvinar to have a major role in coordination and coordinating emotional processes. The pulvinar is located in the thalamus and has been observed to play a role in both attention and emotion processes. It is hypothesized that the pulvinar acts as a mediator…

reuptake is to protect them from destruction to ensure their reuse whenever necessary. If there were no reuptake, the neurotransmitters would risk exposure to enzymes that degrade or destroy them. Thalamus: Thalamus is the gray matter in the brain between the midbrain and the cerebral cortex. If the thalamus is damaged might result in the loss or partial loss of any or all of those sensations. Corpus Callosum: It allows the exchange of information between the two spheres of our brain. If we did…

nderstanding emotion can be difficult to fully do. No one is for sure how exactly the body deals with stimuli that result in physiological reactions and the interpretation of emotions. There are several people who have researched the topic of emotions and have developed theories. Some of these theories of emotion are James-Lange theory, Cannon-Bard theory, and Schacter-Singer theory. None of these theories have been proven to be more accurate than another. The James-Lange theory was proposed…

The thalamus, which is a part of the brain that is responsible for relaying important information, and occipital lobe, which responds to visual stimuli and enables an individual to actually see the image, must be fully-functioning. These parts of the brain will enable neurons to go back and forth between the eyes and brain, producing an image. Creating an artificial retina to replace the malfunctioning retina would enable for the use of the color visual system, so long as the thalamus and…

Thalamotomy is focusing of the thalamus, destroying it in order to block the abnormal brain activity from affecting the muscles, causing the tremor. However, this is the only use for the surgery and because of this, is not normally suggested for Parkinson’s patients. Pallidotomy and Thalamotomy…

Burton 1 The human brain is such a complex and beautiful organ of the body but yet is underappreciated. Many individuals of the human race fail to appreciate the importance of the brain, but that is just how their brain works! Ironic to think, but yet it is just as sad. Since the existence of mankind the human brain has constantly been evolving, growing stronger into the intricate, sophisticated organs of the present. By natural selection, certain people have a brain that is more developed than…
