Connections and Disconnections
Brain taking info and making sense of everything around you. Connections are very critical for
allowing complex behaviour to occur. The brain: does everything for us – all sensory information –
processed by the brain and get perecption of whats going on. Perception vs. sensory. Top down
processing – make sense of what’s going on.
Narrative: idea being built that’s making sense.
• How we process information.
• advertised studied for effects on athletics-psychological information effect ability as an athelete.
Put elbow into ice water – 30-40s baseline, expose participants on how psychology can effect
being athlete, two different types of human hearts – type 1 – low life expenctency, type 2 – high
life expectency. Behavioural test to indicate type of test – cold tolerance after going through
exericise-arm back into ice water (before, half – long period in ice=good heart, other half- can’t
tolerate cold long = good heart). Different score – depend on what they told them. Depends on
what you were told – holding long – good heart = hold longer=behavioural measure.After they
asked if they did this deliberatley-25% said they didn’t-either lying or unaware of what they are
doing, said they changed the water, 60% believe that they have the good heart. Messed around,
20% thought they had a good heart. Sense of understanding of what’s going on – now think you
have a good heart.
• Decieve ourselves.
Brain – making narrative – metabolic costly – emotion, attention, consciousness – outwiegh the cost to
keep the brain going.
Case studied and the connected brain
• Phineas Gage – railroad worker, iron rod went through brain, before – outgoing and friendly,
after – mean, idea of what the sections of the brain are doing.
• Sleep Paralysis: The Hindbrain – Pons (getting visual area- movement, transition between sleep
and awake)Wake up and can’t move, or talk – frozen (sec – min), enter into sleep, pons shut
body down – rematonium – don’t act out dreams. Some people – coming out of the sleep – stays
