In order to determine the role of the amacrine cells they needed to determine the method of bipolar convergence and divergence in ganglion cells. When stimulated individually‚ two different bipolar cells were able to elicit distinct post synaptic potentials in the ganglion cell. Whether a transient or sustained response was to be fired was determined right at that connection (Asari and Meister‚ 2012). In this way‚ the bipolar cell acts similar to the controller (Carpenter and Reddi‚ 190) in a motor

the communication process of neurons in the brain. List some common neurotransmitters and describe their effect on behavior. There are 2 neurons afferent neurons these carry messages to the central nervous system. Efferent neurons carry messages from the central nervous system. Neurons communicate through voltage changes. This can sometimes lead to quick action reaction sequence of voltage alterations. An example would be when you touch something hot and you pull your hand away immediately. One

A Better Understanding: Neurochemistry of Addiction To better understand the fundamentals of neurochemistry‚ a good start is at the brain. The brain makes up the central nervous system and is connected to the whole nervous system that runs through the whole body. The central nervous system receives sensory information and controls the body’s response. For example‚ a pot on a stove would be extremely hot on the hands when the stove is on and would damage the skin. This sensory information is sent

It is the most stretched fiber‚ which goes from the cell body to the last part and sends the neuronal signals. If the axon is bigger‚ the information arrives faster. 2.) Using examples‚ discuss the difference between sympathetic and parasympathetic nervous system activity. Autonomic nervous system is divided in two sections such as sympathetic and parasympathetic nervous system. • Sympathetic nervous system prepares

measuring muscle twitches over electrophysiological parameters are as follows: 1. Students with minimal background can quickly learn to prepare the nerve/muscle preparation for physiological recording and for experimentation dealing with synaptic efficacy. 2. Muscle twitch recordings are population responses‚ which tend to average out individual variation. 3. Under certain experimental conditions (see Fig. 6)‚ one can make deductions about synaptic transmission from muscle twitch measurements. 4. Most electrophysiological

Illnesses’ that affect the brain; such as: bipolar disorder‚ schizophrenia and the many other mental illnesses discovered over the last few decades. More importantly than the epidemic of these illnesses‚ is the way that they are treated and the potential risks associated with treatment. This paper is designed to analyze the risk of an epidemic of deliberate self-harm caused by the utilization of anti-depressants and its impact on the field of biological psychology. The brain; whether of a

THC triggers brain cells to release the chemical dopamine. Such loss of coordination can be caused by smoking marijuana. And that’s just one of its many negative effects. Marijuana affects memory‚ judgment‚ and perception. Under the influence of marijuana‚ you could fail to remember things you just learned‚ watch your grade point average drop‚ or crash a car. Also‚ since marijuana can affect judgment and decision making‚ using it can cause you to do things you might not do when you are thinking
