Psychology studies different areas of the mind and behavior‚ especially the link between biology and behavior. Biological psychology explores behavior through genetics‚ evolution and physiological‚ especially through the study of the nervous system. Biological psychology explores biology in an effort to understand behavior. It investigates how human brain connects to the consciousness. In order to understand biological psychology research has been done to gather background information on the history

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

The brain of an average human being contains 100 billion nerve cells or neurons. Billions more are found in other parts of the nervous system. Neurons come in all different sizes and shapes‚ but they all seem to be specialized to receive and transmit information. Neurons are made of neurons which contains chromosomes and genes‚ a cytoplasm which keeps the cells alive and a cell membrane that encloses the whole cell. Neurons are different from other cells because they have small fibers that branch

Neural & Synaptic Transmission The nervous system is made up of neurons and glila cells. Neurons are the basic communication links in the nervous system. Glila cell provide support for neurons and contribute to communication. Neurons normally transmit a neural impulse (an electric current) along an axon to a synapse with another neuron. The neural impulse is a brief change in neuron’s electrical charge that moves along an axon. It is an all-or-none event. Action potential triggers

They are generally found in many of the body’s tissues such as within the cytoplasm of the cells of the heart‚ liver‚ muscle‚ and skin but the signs and symptoms of the disease are limited to the nervous system. The disease presents with epileptic seizures followed by progressive central nervous system degeneration beginning with myoclonic seizures‚ tonic-clonic seizures‚ focal occipital seizures‚ intellectual decline‚ severe motor and coordination deterioration‚ and constant myoclonus (Gentry‚

cell bodies called the peripheral nervous system. The PNS contains all of the nervous tissue outside the brain and spinal cord. Afferent (sensory) nerve fibers-conduct nerve impulses toward the CNS Efferent (motor) nerve fibers-conduct nerve pulses away Sensory Somatic System – Carries nerve impulses from the senses to the CNS and also carries the impulses to the skeletal muscles and glands (this allows us to react to the environment) Sensory Somatic System – Composed of 12 pairs of cranial
