03:07 AM rue_bed2: some strange sensation as I dig deeper into understanding how the human brain operates
03:12 AM rue_bed2: its like studying a strange architecture, like an old computer that uses logic in pulses and doesn't have the system layout were used to
03:12 AM rue_bed2: hmmm
03:18 AM veverak: reading book about neuroscience?
03:18 AM veverak: :)
04:02 AM Jak_o_Shadows: I was on the sidelines of an arguement about the number of senses humans have once
04:02 AM Jak_o_Shadows: somebody was argueing it's only the external ones
04:02 AM Jak_o_Shadows: the other was saying that the sense of where your body is is another sense
04:03 AM Jak_o_Shadows: I think that it's the latter, but that the internal ones are like, fusion processes
04:04 AM mrdata: in school we learn BS like there are only five senses: sight, hearing, touch, taste, and smell
04:05 AM mrdata: thats like saying there are only four elements
04:05 AM mrdata: they are categtories of senses
04:05 AM mrdata: when i suffered a stoke in 2004 i lost light touch and proprioception on my left side
04:05 AM Jak_o_Shadows: Yeah
04:06 AM Jak_o_Shadows: i'd argue that sense of body position is a fusion of like, muscle forces, and sight
04:06 AM mrdata: a buddy of mine likewise lost his sense of temperature
04:06 AM Jak_o_Shadows: that ones awkward
04:07 AM mrdata: but he also had a sense of humidity
04:07 AM mrdata: so on hot humid days in toronto he would crank the air conditioner so that it dried the air better
04:08 AM mrdata: so proprioception is the sense of where your body is
04:09 AM mrdata: astronauts seem to lose this temporarily while exposed to microgravity
04:10 AM mrdata: my stroke was right hemisphere parietal lobe sensory-motor cortex
04:10 AM mrdata: so this is the spot where that sense is processed
04:10 AM mrdata: (for left side of the body)
04:29 AM Jak_o_Shadows: huh, i never knew that astronatus lost it for a bit
04:29 AM Jak_o_Shadows: makes some kinda sense, but is strange
04:34 AM mrdata: implies that gravity is crucial for the sense to work
04:34 AM veverak: well
04:34 AM veverak: we simply have something like accelerometer in our heads
04:35 AM veverak: :)
04:35 AM mrdata: inner ear gives you a sense of balance; this is different again
04:37 AM mrdata: ok so grouping light touch, heavy touch, pain, temperature, humidity, proprioception all into "touch" does damage to your comprehension of th complexity of this all
05:07 AM Jak_o_Shadows: yeah
05:07 AM Jak_o_Shadows: agreed
05:07 AM Jak_o_Shadows: kinda amazing that you can adapt and get some sense back
05:07 AM Jak_o_Shadows: that'd be hard to program
