neuron science random fun facts
  1. Despite slow individual neuron dynamics (determined by its time constant), a population of neurons spiking in an asynchronous manner can respond arbitrarily fast.
  2. For noisy injection current, as variance increases, neurons start to respond more linearly before the threshold is met.
  3. Excitatory and inhibitory inputs both decrease time constant. When exc. and inh. inputs combine into a low and irregular firing rate, low mean and high variance in membrane potential.
  4. Parkinson's disease comes from the degeneration of dopamine neurons in the substantia nigra, and it causes problems in initiating and scaling movements, which means motor functions rely on motivation rewards.
