Question

1. Many drugs affect how neurotransmitters are released, reuptaked, degraded and/or removed. Find a specific example of a drug and film yourself explaining how it would affect neurotransmitter release, reuptake, degradation or removal. Include in your discussion the steps of synaptic transmission.

2. The spinal cord is extremely well organized in how it is able to send afferent and efferent information to and from your brain. Explain the pathways that both painful touch and non-painful touch information would follow from the fingertips up to the cortex of the brain where the information will be processed. Include the roles of the white matter, gray matter, roots, rami, and any and all decussations. Additionally, explain the pathway that a motor command from the primary motor cortex of your brain would follow to move the muscles of the fingers. Your answer must include the roles of the white matter, gray matter, roots, rami, and any and all decussations.

3. Hydrocephalus is a sudden life-threatening disorder for adults but less so for newborns. Film yourself explaining why adults with hydrocephalus would need intervention (medical care) much more rapidly than infants with the same problem. Include in your discussion the flow of cerebral spinal fluid (where it starts, the spaces it passes, and where it ultimately ends).
