Document Summary
Tay- sachs waste building up in brain cells causes the death of neurons, lysosomes. Area affected by locked in syndrome is the medulla. A nerve is long strand made up of thousands of neurons. A lack of dopamine is associated with parkinson"s. The primary immune response in the cns comes from the action of microglia. Temporal summation a neuron had told brain and other neuron that"s its important ( the beeps are milliseconds apart) Spacial summation adding together different signals from different areas of the brain that has arrived at the same part. Know the neurotransmitters and their functions not their chemicals bases (gases and peptides we won"t cover, don"t know the cranial nerves. Voltage gated sodium channels and then potassium voltage gated channels open as well. Potassium leak channel and na/k pump work hard to restore. In myelinated neurons the signals jump from node to node.
