Document Summary

Statistically determine id an association between variables exist. Tests: a methodology designed to falsify your hypothesis (or predictions: more dangerous to be in the soil (possibility of drowning, rain makes it easier for the worms to travel. Axon- long, tail like structure that leads from neuron body to synapses, which connects to dendrites. White-matter: in the cerebral cortex, bundles of axons connecting the bodies of some of the neurons with the dendrites of others. Short-term: blow to head causes quick stretching of axons (deflated balloon analogy) Long-term: affected neurons slowly die and tau proteins are a by-product. Confirmed via autopsy or structural neuroimaging (pg 123-124) Brain damage inference: cause: region-specific neuron death (e. g. hippocampus, effect: specific change to behaviour (e. g. memory loss) Problem: cte is only diagnosable via autopsy. Regions of significant neuron death unknown until patient dies. Effect: behaviour changes reported by patient and loved ones: memory loss, impulsivity, emotion regulation.
