Psychology chapter three vocabulary nervous system‚ a collection of hundreds of billions of specialized and interconnected cells through which messages are sent between the brain and the rest of the body. The nervous system consists of the central nervous system (CNS)‚ made up of the brain and the spinal cord‚ and the peripheral nervous system (PNS)‚ the neurons that link the CNS to our skin‚ muscles‚ and glands. And we will see that our behavior is also influenced in large part by the endocrine

“The Last Hippie” is a short chapter from Oliver Sacks’ An Anthropologist on Mars: Seven Paradoxical Tales. The chapter is centered around Greg‚ one of Dr. Sacks’ patients‚ and how his troubling teenager years subsequently led to him become an amnesiac who‚ “seemed bland‚ placid‚ and emptied of all feeling‚” (Sacks‚ 1996‚ p.46). Although Greg’s story was very interesting to read‚ I did find it relatively difficult to follow along‚ and encountered many challenges while reading the chapter. All of

Through the PET scan they found that people who had reduced cellular metabolism in the region of the hippocampus were associated with the Alzheimer’s disease. One of the researchers of team argues that the results should be replicated; however‚ a great advantage of this new brain imaging technique could be very useful to detect and prevent the Alzheimer’s

sample size Paragraph 3 (Bremner et al 2003) Aim: To measure the structure and function of the hippocampus in women with or without childhood sexual abuse. Procedure: Thirty three women participated in the study that had or had not suffered abuse. They were given verbal memory tasks which were measured with a PET scan. Findings: The women with PTSD and had abuse in the past had a 16% smaller hippocampus compared with the ones without Critique: Gender bias‚ cultural bias‚ small sample size Paragraph

We also consider the role of the mPFC in a broader neural circuit for extinction that includes the amygdala and hippocampus.

They also showed differential morphological changes in hippocampus and amygdala. We observed decline in CA1‚ hilar region and dentate gyrus (DG) volumes with basolateral amygdalar hypertrophy (BLA).

The PRL in CNS comes from local synthesis and transport from the blood circulation. Besides‚ the presence of PRL receptors has been identified in different brain regions‚ such as choroid plexus‚ olfactory bulb‚ and hypothalamus [54]. Since 1980s‚ studies have suggested the relationship between PRL and CNS tumors. Ciccarelli et al reported in 2001 that high PRL levels and increased PRL receptors were found in some of the patients with meningiomas and schwannoms‚ indicating that PRL might be involved
