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 disorders and phenomena. Neurotransmitters: The synapse is the connection between nerve cells

The nerve impulse The information is transmitted by polarity changes in the membranes of cells due to the presence of neurotransmitters that alter the ionic concentration inside the cell. Moreover‚ inside the neuron proteins and ions are negatively charged . This difference in ion concentration also produces a potential difference between the outer membrane and within the cell . The value reached is about -70 millivolts (negative inside with respect to the value of positive charges outside

Many scientific have concluded that neurotransmitter have an important role in the production of hormones. Some researchers have found that patient with anorexia nervosa also have abnormal levels of certain neurotransmitter. Lower levels of the neurotransmitter serotonin are connected to bulimia‚ depression and food disorders; lower levels of nor epinephrine was found on anorexic patients. It is possible that abnormal levels of the nor epinephrine neurotransmitter could cause weight loss on anorexic

As all behaviour is associated with changes in brain function‚ psychopathology will be caused by changes in either the structure or function of the brain. This might involve changes in the size of brain structures‚ or in the activity of brain neurotransmitters and hormones. For example‚ biological

receiving and transmitting information. Each part of the neuron plays a role in the communication of information throughout the body. Neurotransmitters A neurotransmitter is a chemical substance through which one neuron sends a message to another. Neurotransmitters are transmitters that give off chemical reactions to neurons. There are several types of neurotransmitters and each type controls different functions like muscle control and triggers. Axon An Axon is a long‚ arm like structure that transmits

Figure 1 shows a neuron‚ as indicated on the diagram; the dendrites are the receivers of information for that cell. The dendrites receive neurotransmitters from the synapses that connect to it and if enough are present‚ an action potential is caused which then travels down the axon to the terminal buttons also known as synapses. There are electrical and chemical synapses in the body although the

across the United States have raised awareness of the harmful effects of drug use on the human body‚ on adolescents in particular. How do drugs damage a teenager’s brain? The function of neurotransmitters in the teenage brain is often targeted and altered by psychoactive substances. The interference of neurotransmitters can directly damage the fragile developing neural connections‚ and the use of these substances alters perception and may interfere with developing perceptual skills.
