highlights just how little the circuitry of the brain is currently understood in terms of depression. Also by specifically identifying that not only its interactions with glutamate and the mTOR process‚ but the fact that it takes place in the pre frontal cortex as opposed to the hippocampus are vital to the antidepressant effects observed in those treated with ketamine. As is commonly found with studies producing such dramatic and potentially profound results‚ those involving ketamine have exposed many unanswered

Organization of the human body Human anatomy and physiology – study of the structure and function of the human body. Anatomy- the scientific discipline that investigates the structure of the human body. Physiology – The scientific discipline that investigates the process of functions of living things. 6 Structural levels 1. Chemical level – atoms combine to form molecules 2. Cell level – Molecule form organelles 3. Tissue level – similar and surrounding material make up tissues

Cortisol – The Stress Hormone Where is it made? Within the adrenal glands there is a layer around the perimeter of the gland that is known as the adrenal cortex. A portion of the cortex labeled the Zona fasciculata is where the hormone Cortisol produced. The Zona fasciculata is primarily responsible for the production of various Glucocorticoids‚ such as Cortisol. What is it? Cortisol is a corticosteroid hormone it is extremely vital to the body- when released increases both blood pressure

A Review of Facial Nerve Anatomy Terence M. Myckatyn‚ M.D.1 and Susan E. Mackinnon‚ M.D.1 ABSTRACT An intimate knowledge of facial nerve anatomy is critical to avoid its inadvertent injury during rhytidectomy‚ parotidectomy‚ maxillofacial fracture reduction‚ and almost any surgery of the head and neck. Injury to the frontal and marginal mandibular branches of the facial nerve in particular can lead to obvious clinical deficits‚ and areas where these nerves are particularly susceptible to injury

In recent years‚ the study of the mechanisms affecting and causing Alzheimer’s disease has been closely studied. Alzheimer’s disease is the main cause of dementia in that it causes rapid atrophy of the outer cortex of the hippocampus in the brain. As a result‚ this cell degeneration ultimately gives rise to the array of cognitive impairments‚ including memory loss‚ confusion‚ irritability‚ loss of stream of consciousness‚ and depression. Cranial nerve one (CN I)‚ serves as the olfactory nerve where

Drilling into the skull of a young man he began to funnel a stream of sulfuric acid into the head of his unconscious victim to create a zombie to fulfill all of his fantasies. Dead within a day‚ he mummified the head of his victim placing it in the freezer beside the skulls of those who came before. Dismembering the remnants of the body he placed skin‚ blood‚ and bone into a fifty-gallon vat of acid dissolving what was left of the young man. This is the mind of Jeffrey Dahmer‚ he murdered not in

who use the left side are more logical‚ detail-oriented and analytical (Novotney‚ 2013). In order to acknowledge these differences this essay will highlight what is meant by lateralisation of the brain and the specialisation of the human cerebral cortex. Equally as important‚ is to explain how handedness has developed and how it relates to cognitive functioning. Finally‚ by looking at how we study the brain and different research techniques used‚ a thorough analysis can be discussed. The two hemispheres

The risk taking in teenagers is linked to the immaturity of PFC. Another part of the cortex is the anterior cingulated; it helps us make up our minds. While teenagers are taking risk‚ adults are able to rapidly sort out and get an idea of what to do. Adults are able to assess and respond to mixed signals allowing them to avoid certain dangerous
