There are five major parts of a neuron, the axon, soma, dendrites, the axon hillock and the terminal buttons. The axon transmits the neural signal. The stoma is where signals from the dendrites are joined and passed on. It serves to maintain the cell and keep the neuron functional. The dendrites help increase the surface area of the cell body. They receive info from other neurons and transmit electrical stimulation to the stoma. The axon hillock controls the firing of the neuron. The terminal buttons are responsible for sending the signal on to other neurons.
2. Explain the interaction between the central nervous system and peripheral nervous system.
There are three stages that the nervous system processes information to the effector cells, those three stages are: sensory input, integration, and motor output. The central nervous system integrates information and the peripheral nervous system transmits sensory and motor signals to the rest of the body.
3. If the corpus callosum is severed, how might this affect the way that we perceive the world.
It will limit the communication between the two halves of the brain. Being that there is lack of communication language will be tough will be tough and so will processing images so it will be hard to identify objects.
4. How might modern brain imaging techniques be useful to psychologists?
The brain structure controls everything in our body when different things happen different parts of your brain produces different brain activity. So with the modern brain imaging techniques psychologists can study brain activity of a normal person and compare that to the brain of a mentally ill person. This will help them understand the nature of the brain activity.
5. Explain at least one potential implication for the genetic diagnosis of traits such as intelligence and criminality.
One potential implication is the twin study; fraternal
