• presynaptic neurons send signals
• postsynaptic neuron receives the signal from presynaptic neuron
• synapse is the gap between two neurons
• the gap between to neurons is called the synaptic clef
• rem stands for rapid eye movement
• sleep is a condition of body and mind where the neurous system is inactive
• over the age of 65 deep sleep stops
• stage 1 of slepp is awake it has high frequency and low amplitude
• stage 2 = nrem1 the lightest stage of sleep, high frequency low amplitude
• stage 3 = nrem2, light sleep, TETA waves occur, high frequency mainly low amplitude with abit of high amplitude
• stage 4 = nrem3, deep sleep, when sleep disorders can occur
• REM sleep, high frequency low amplitude, dreaming, muscule paralasis
• Phineas Gage, was a railway worker who on the 13th September 1848 had a 3ft 7in rod blown through his fronatal lobe, he survived, he was now impulsive after being described as kind before the accedent, this helped psychologists to work out that the frontal lobe controls our personality
• neuroplasticity is where the brain can repair itself
• frontal lobe controls voluntary movement, speech, and emotions, if damaged it can effect personality and make people impulsive
• the parental lobe is the part of the brain that controls the reciving and processing of sensery imput
• the oxipital lobe controls the eyes and vision
• the temparel lobe controls memory
