1. Neuronal Communication action is electro-chemical
  1. Neuronal Communication action is Binary
  1. Brain is Modular
  1. Brain has plasticity

The function of a Neuron depends on its physiology.

Cells fire or they don’t; there is no in-between.

 Different brain regions are responsible for certain functions Plasticity means change and adaptation.

 

Electro:

Axons, Ion transfer, myelin increases effiiciency

Chemical:

Terminals, Vesicles, Neurotransimitters:

  • Ach
  • Glutamate
  • Serotonin
  • Dopamine
  • GABA
  • Norepinephrin
 Some are excitatory, some are inhibitory. Frontal Lobe, Parietal Lobe, Occipital Lobe, Temporal Lobe

Language centers:

  • Broca’s
  • Wernickie’s

Amygdala, hippocampus, corpus collosum (split brain)

Neurons don't grow back if they die.

Although neurons do not divide or repilicate like, for example, skin cells, neurons can grow new connections with other neurons. So although there is around 100 billion neurons, there are trillions of synapses.
