Describe the molecular mechanisms of hippocampal LTD at the introduction level (Introduction to Neuroscience College Level). Provide diagrams from the web or from a textbook or a website to complement your explana

Subject: Neurophysiology    Imagine that you have the NMJ preparation but your voltage clamp and intracellular microelectrode is broken.  You decide to depolarize a nerve to threshold using KCl in the bath.  What concentration would you use?  Explain your rational using Goldman, and Nernst.

Intro to Neuroscience Question: What effect would a bilateral lesion to the amygdala have on a person? Group of answer choices The person would not be able to store new memories There would be no adverse effects following the lesion The person would be unable to experience fear The person would lose their circadian rhythms The person would have difficulty retrieving previously stored memories   Please explain why this answer choice is correct. Why did you chose that specific answer choice?

Upper motor neuron damage:   Results in activation of the extensor reflex Results in activation of the fight or flight response Results in weakness that becomes spasticity Results in spasticity that becomes flaccidity

Explain how the damage done to the brain in Parkinson’s creates the motor symptoms of the disease. You can either write a thorough paragraph below or create a model and attach it.

Describe two different ways in which we can induce reorganization/plasticity in primary motor cortex.

Intro to Neuroscience Limbic System, Emotion, Reward, and Addiction List of the effects of natural rewards and commonly abused drugs on reward circuits

Intro to Neuroscience Question: Damage to the cerebro-cerebellar pathway would be most likely to cause…. Group of answer choices Dysmetria Gait disturbances Huntington’s disease Parkinson’s disease   Is this reasoning correct?  The cerebro-cerebellar pathway involves connections between the cerebrum and the cerebellum. These connections play a role in the planning, initiation, and timing of movements, as well as motor learning. Given the functions associated with the cerebro-cerebellar pathway, damage to it would most likely lead to issues with the accuracy and timing of movements. Among the options provided: Dysmetria is the most likely outcome. Dysmetria refers to the inability to judge distance or range of a movement, leading to overshooting (hypermetria) or undershooting (hypometria) a target.

True/False: Either abnormally strong or abnormally weak reflexes may indicate a neurological problem.
