Thalamus

At the spinal level, the PNS and CNS are bilaterally symmetrical. And studies have shown that the two sides of the spinal cord are not independent due to the findings that unilateral peripheral nociception results in contralateral responses (Koltzeburg, 1999). The contralateral pain was perceived at a lesser magnitude and has a delayed response. This contralateral pain phenomenon can be attributed to a similar pathway as central sensitization leading to secondary hyperalgesia. Primary…

system contains the hippocampus, thalamus, hypothalamus, and amygdala. The hippocampus is located in the temporal lobes on each side and is involved with making memories, neurogenisis takes place here. The thalamus is a mass of cell bodies located within each cerebral hemisphere and processes and interegates sensory informations except for smell and relays sensory information to cerebral cortex. They’re like traffic cops. The hypothalamus is located right below the thalamus and is the size of a…

stimulus, such as pain. 2. Pain receptors are excited by any type of tissue damage. 3. Referred pain is a phenomenon when you feel pain in an area other than where the pain originates from. 4. The thalamus and cerebral cortex are the parts on the brain that interpret pain impulses. The thalamus establishes the awareness of pain, and the cerebral cortex verifies the severity of the pain, discovers where the pain is coming from, and responds to the pain. Five Special Senses 1. Sense of Smell…

After all of Aaron’s own problems he still persevered in the end. It was quite a nice surprise when Aaron noticed someone was at the door, he cautiously opened it to find Sullivan standing there. Sullivan returned because Aaron sent a letter to the relatives explaining some health concerns and to send Sullivan back. While Sullivan and Aaron were sitting having lunch, there was a rattle at the door, and in came Mr. Kurlander to come tell the boys of the great news about making $68 a month and…

For example, I performed gene expression profiling in the developing thalamus of Gbx2-deficient transgenic mice using DNA microarray and elucidated the genetic cascade directing the embryonic thalamus development. I have published a number of papers in highly ranked peer-reviewed journals in this regard. Before pursuing biomedical research, I attended a three-year professional program…

that although cocaine dependant individuals have decreased ability for stimulus-response learning, their ability to make basic associations remains intact (Vadhan, 2014). As previously mentioned, cocaine gives the user a feeling of euphoria through the increased release and decreased reuptake of the dopamine neurotransmitter within the synaptic gap, especially in the nucleus accumbens (Volkow, 1997). Over time, the repetitive influx of dopamine molecules can have detrimental effects on…

spoken language. The temporal lobe’s primary functions are speech, memory, auditory perception, and emotional responses. The occipital lobe controls visual perception and color recognition. Other areas of the brain that have roles in cognition are the thalamus, amygdala, putamen, hippocampus, caudate, and the…

Psychological Disorders Response DID, Dissociative Identity Disorder according to David Myers (2014) is “A massive dissociation of self from ordinary consciousness characterizes those with dissociative identity disorder (DID), in which two or more distinct identities are said to alternately control the person’s behavior.” (p. 638). Symptoms of this disorder are (1) Loss of memory for periods of time of events and people. (2) Thoughts of committing suicide and attempts made. (3) Feelings of…

Meditation In this ever growing and constantly changing lifestyle of ours, we experience a lot of people struggling to keep up to their hectic life and see them constantly breaking their stress in the form of anger, sadness, depression and many other situations that prolongs our stress rather than reducing them. If we look back into the juncture of growing, children are far better at handling stress since they don’t build up stress as the adults in our community do. Children often express their…

While I was sitting down, working on my Psychology homework for Professor Bacon, I realized I was quite hungry. The part of the brain that made me sense my hunger is the Hypothalamus. The Hypothalamus is part of the forebrain, directly below the Thalamus. It is responsible for motivation, and emotional responses such as hunger, thirst, sex drive, body temperature, rage, pleasure, and terror. Then I thought “Wow, I could go for some good pizza right now.” The Insula controlled my desire for…
