-
Communicate with people outside the bottle
Electrical activity can communicate, etc
-
Seemed crazy at the time, but people are using brainwaves today
-
Without sensory or motor input, it would die
Higher the spinal cord missing, the less emotional input
Neil Hebb, sensory escalation (soundproof room, blinded, etc), people would ask to get
out even though they were being paid well.
Would he really survive? Would he really be Harvey if he put his brain in a bottle?
-
Made a robot with every bit of behavior was identically like a human
Would it be a human? Mental attributes of human?

Harvey
In front of
Crinkly, groove, sulci, grey matter
Every brain is a little difference
Lateral fissure (deep one)
Some organization to it, like the dorsal, medial, etc
Corpus callosum holds the hemispheres together (hard like a callous)
Lots of differences between them
Made up of hemispheres
Left, right hemisphere
Connected by fibres, corpus callosumm
Four lobes: frontal, temporal, parietal and occipital
Grooves on cortex are sulci and bumps are gyri
Large grooves = fissures
Forebrain
-
Stuff in middle, like flower
Cerebellum
Fibres go down into spinal cord
Corpus callosum on top of it (white in MRI's because little water in it, just like the skull)
Cerebellum also has sulci and gyri too, just smaller
Canal that has fluid in middle
Connects forebrain and spinal cord
Brainstem
-
Leading down
Connects brainstem and forebrain
Can't feel anything if you don't have it (PNS)
Connects to different sections of body
Gets information from skin
Vertabrae
PNS is organized too, just like everything else
Spinal cord
-
CNS
