Study Notes
Neuroscience and Neurological Disorders Overview
- Neuronal influx of Na+ is facilitated by the Na+ – K+ pump
- K+ enters neurons through voltage-gated K+ channels
- Na+ enters neurons through voltage-gated Na+ channels
- Chemical gradient of Na+ across the membrane is equalized
- Membrane potential becomes more negative during this phase
- A post mortem brain is an example of haemorrhagic infarction
- Meningiomas are not all benign tumors
- Raised intracranial pressure is not advised for lumbar puncture in initial assessment
- Subarachnoid hemorrhage is the presumed pathological basis of a severe occipital headache
- Meningitis is the presumed pathological basis of a sore throat, chills, and fever in a 4-year-old boy
- Alcohol interferes with theta wave pattern essential for hippocampal memory formation
- Scopolamine is known to impair memory formation by interfering with wave formation
