When comparing the Parasympathetic and Sympathetic systems, what conclusion can be reached with respect to many of the organs and their functions shown in Model 1?

Why are there multiple receptor subtypes for eachneurotransmitter? Why not a few receptors and lots ofneurotransmitters acting on each receptor?

What evolutionary advantage does tight oligodendrocyte myelination in the brain provide and which protein is responsible?     slower conduction velocities in the spinal cord, PLP/DM20     greater space for neuron growth and density in the cranium, PLP/DM20     greater space for glia and blood vasculature in the cranium, PO     perception of distant objects, PO/DM20

Describe the concept of ‘brain maps’ and some of the experiments by Penfield and others that led to and supported this idea.

Discuss and draw the Hodgkin–Huxley model of action potentials in neurons

In the past, aspiring London taxicab drivers underwent a rigorous education that required them to learn the location of about 25,000 streets in the city. The average posterior hippocampus of London cabbies, as revealed by magnetic resonance imaging, was larger than that in a comparable group of London bus operators, who follow a fixed route and so do not have to learn a detailed map of the city (Maguire et al. 2000). In addition, the more years of taxi driving, the larger the posterior hippocampus (Maguire et al. 2006). What does this research tell us about the interplay of the environment and genetics in the development of adaptive navigational skills in human beings? Please don't write from any online source.

Compare and contrast the basic anatomy of the parasympathetic and sympathetic systems, includingcentral nervous system locations, ganglia locations, pre- and post-ganglionic neuron relative lengths,and ganglionic and effector neurotransmitters.

Make a diagram of Central nervous system?

In PET scans, red areas are brain regions that are most active, while blue, yellow, and green areas are least active. Figure 13.24 shows PET scans of normal brain activity (left) and (right) of the brain of a person while using cocaine. The frontal lobes of the brain hemispheres are toward the top of the scans. Their neurons play major roles in reasoning and other intellectual functions. Looking at these scan images, how do you suppose cocaine may affect mental functioning?
