During brain development, the process of synaptogenesis is a crucial one. Which of the following is correct about synaptogenesis? a. Produces 25% more synapses initially than the amount maintained in adults. b. Reaches its peak between 8 months and 2 years of age, depending on brain area. c.

There are unique reciprocal connections between cortical and subcortical regions and each of these loops make a different contribution to behavior  a. The connections from subcortical areas to the motor cortex are through the thalamus. b. There are no direct connections from the subcortical areas to the spinal cord. d. a. and c. only.

Alzheimer’s disease is a devastating neurodegenerative disease. Discuss approaches used to study the disease, giving examples of specific techniques and models, and evaluating their advantages and disadvantages. Discuss possible reasons for why effective treatments have not yet been developed. Use figures and diagrams to illustrate your answer. (This is a neuroscience question)

The major reason the cortex is so convoluted in humans is                    . A. to accomadate the large surface area of the cortex inside the skull B. the wrinkles protect the cortex from stretching C. the cortex shrinks during development D. the folds allow divisions of the cortex to communicate with each other

Epilepsy Epilepsy is a neurological disorder that disrupts neural activities and causes recurrent seizures. About 70% of people with epilepsy can be treated with medication to prevent seizures from occurring. If medication does not work, surgery is an option for some patients. One of the procedures involves cutting the brain so that the seizures cannot be spread to other parts of the brain. An individual was suffering from violent headaches and blurred vision for several years. A doctor determined that this individual had a tumour on the anterior pituitary. Explain why this person was experiencing blurred vision.

Describe the functions of the following brain regions: a. Cerebrum (cerebral cortex). b. Cerebellum c. Diencephalon d. Brain Stem
