BIOLOGICAL APPROACH

the approach arouse out of attempts to understand two major issues the relationship between mind and body and the influence of heredity on behavior. Mind is the inner subjective experience of conscious awareness. and a nervous nervous system consist of many nerve cells or neurons. the nerve cell has a cell body dendrites and axon. most cell body are located in the brain or the spinal cord. the dendrites and axon are extension of cell body. the dendrites carry signals or impulse  toward the cell body. the axon carries impulse away from the cell body. axon vary in length and thickness. the dendrites and axon are sometimes called nerve fibers.
and i learned that sensory neurons located in the eyes and ears while motor neurons are responsible for initiating muscles activity. the neurons which comprise the CNS are often called inner-neurons because they are intermediate between  sensory and neurons the basic unit of the neuron system is the neuron.
A neuron is like a wire through which an electrical signals called a nerve impulse. brain stem is the region at the top of  the spinal cord. the medulla a small swelling at the top of the spinal cord. Pons a Latin for ''bridge'' provides connection between the cortex and cerebellum. And reticular formation means "finely inter woven" and  limbic system connection both up to the cortex down to the spinal cord acts a relay network controlling sensory input; as such it plays a key role in regulating our arousal level controlling alertness and sleep. the brain and nervous system function integrated system to regulate our behavior.
Electro electroencephalograph or EEG writing the electricity of the brain. EEG were used to identify synchronize patterns of activities associated with perceptual recognition;research  found that was a burst of   activities at that moment when an ambiguous visual stimulus was recognized.
 electrical stimulation in this techniques small cluster of cell are activated by inserting a fine wire into the desired area and then applying a small electric current.
Computerizing imaging which use to use computer to assist in analysis of information are enabling research to gain insight about brain function. like CAT scan, x-ray ,PET scan MRI
both neural and chemical processes are important to our understanding of the relationship between the brain and behavior. the mind is ultimately a product of brain with a physical basis this assumption is often referred to as materialism  at the same time no one can presently explain precisely how mind and brain connected. despite the progress made in understanding more basic function.
