Subject field(s)
  • Nervous System
DEF

A diffuse network of neurons running from the hindbrain, into the midbrain and up into the thalamus and hypothalamus of the forebrain. It receives input from most of the senses and sends outputs to many higher brain centres, filtering the sensory information that reaches the conscious brain.

CONT

When you wake up in the morning and become conscious ... there is a little switch that clicks on in your reptile brain. This is called the reticular activating formation (RAF). When it is off, you are asleep or in a coma. When it's on, you wake up and you walk around absorbing incoming signals and stimulus.

French
