BIPN 150 Lecture Notes - Lecture 9: Independent Community And Health Concern, Cytoskeleton, Cell Division
Document Summary
Lis1 & dcx connect microtubule lattice with motor which allows to pull along radial glial cell protrusion. Leading edge of neuron - cytoskeleton has to reorganize (microtubules) to drag nucleus along. Ca2+ channel, voltage-gated na+ channel: seizure: disruption in excitatory / inhibitory (e/i) balance in the brain, what happens in the brain during a seizure, brain cells either excite or inhibit (stop)other brain cells from sending messages. Usually there is a balance of cells that excite and those that can stop these messages. However, when a seizure occurs, there may be too much or too little activity, causing an imbalance between exciting and stopping activity. The chemical changes can lead to surges of electrical activity that causes seizures. Instead, they are a symptom of many different disorders that can affect the brain. Some seizures can hardly be noticed, while others are totally disabling: types of seizures:
