What is Brain Chemistry? Brain chemistry or neurochemistry is the complex system which allows the brain to function with the use of chemicals known as neurotransmitters which move information around in the brain. Every person’s brain chemistry is slightly different‚ and a number of things can play a role in the levels of various neurotransmitters in the brain‚ and how those chemicals affect the brain’s function. It is believed that difference in brain chemistry may explain a variety of behavioral

Behaviour: Actions and responses that we can directly observe. Mind: Internal states and processes‚ such as thoughts and feelings‚ that cannot be seen directly and that must be inferred from observable‚ measurable responses.

particular body system. I decided to focus on the neurological system and to do my research on cerebral palsy. The nervous system is a delicate body system made up of many parts and has many functions. The nervous system has three main functions- sensory‚ integration‚ as well as motor. There are two components or the nervous system (the central and peripheral nervous system) as well as two subdivisions (the autonomic or involuntary and the somatic or voluntary nervous system) that are complex

Almost all of us may feel this physiological load‚ which can be compared to carrying a 300 kilogram barbell at all time. It is a burn on your nervous system‚ hormones and immunity. Yes‚ I am talking about stress. Stress is a catabolic process within the body‚ and in a world where there is up to down‚ left to right‚ yin to yang and anabolic to catabolic‚ there has to be anabolic stimulants to promote

Biological Basis of Behavior Neurons Neuroanatomy: Study of the parts/function of a neuron. Neuron: Nerve cells. Their parts are dendrites‚ soma‚ axon‚ Myelin sheath‚ and Terminal buttons. Dendrites: Rootlike structures that form synaptic connections with other neurons Soma: The body of the neuron‚ contains the nucleus and other cell organelles Axon: Wirelike structure that connects the soma to the Terminal buttons Myelin sheath: Fatty covering of the axon that speeds up neural

Definition Reflex tests are simple physical tests of nervous system function. Purpose A reflex is a simple nerve circuit. A stimulus‚ such as a light tap with a rubber hammer‚ causes sensory neurons (nerve cells) to send signals to the spinal cord. There‚ the signals are conveyed both to the brainand to nerves that control muscles affected by the stimulus. Without any brain intervention‚ these muscles may respond to an appropriate stimulus by contracting. Reflex tests measure the presence and
