Douglas what of mcgill university in 54 00:10:16,619 --> 00:10:13,930 montreal is the chief scientist behind 55 00:10:18,179 --> 00:10:16,629 the tree experiments his devoted as 56 00:10:20,460 --> 00:10:18,189 careers trying to understand how the 57 00:10:23,069 --> 00:10:20,470 vestibular system or our inner ears 58 00:10:25,859 --> 00:10:23,079 balance and orientation Center how its 59 00:10:28,980 --> 00:10:25,869 functions and how specifically it adapts 60 00:10:31,169 --> 00:10:28,990 to a weightless environment the idea for 61 00:10:33,900 --> 00:10:31,179 the torso rotation experiment first came 62 00:10:35,489 --> 00:10:33,910 to dr. watts several years ago when one 63 00:10:37,530 --> 00:10:35,499 of his colleagues suffered an injury 64 00:10:40,859 --> 00:10:37,540 that required the wearing of a rigid 65 00:10:42,449 --> 00:10:40,869 next place the colleague mission to dr. 66 00:10:43,980 --> 00:10:42,459 Watson after a few minutes of walking 67 00:10:47,819 --> 00:10:43,990 around on the laboratory began to 68 00:10:50,730 --> 00:10:47,829 develop symptoms of nausea muscle 69 00:10:53,549 --> 00:10:50,740 location is a term that we use to 70 00:10:56,040 --> 00:10:53,559 describe a person who rigidly fixes 71 00:10:57,449 --> 00:10:56,050 their head to their torso and such that 72 00:10:58,889 --> 00:10:57,459 when they have to turn their head to the 73 00:11:02,340 --> 00:10:58,899 right or to the left they have to turn 74 00:11:05,489 --> 00:11:02,350 their whole torso as well what's the 75 00:11:07,019 --> 00:11:05,499 rotation is example of an abnormal motor 76 00:11:08,699 --> 00:11:07,029 strategy in which the subject 77 00:11:10,739 --> 00:11:08,709 concentrates on a body frame of 78 00:11:13,590 --> 00:11:10,749 reference rather than the external world 79 00:11:15,119 --> 00:11:13,600 and this causes us to suppress the 80 00:11:18,900 --> 00:11:15,129 normal way that our vestibular apparatus 81 00:11:21,329 --> 00:11:18,910 in our brain likes to operate another 82 00:11:22,919 --> 00:11:21,339 good example of suppressing the normal 83 00:11:25,110 --> 00:11:22,929 way that our brain and vestibular system 84 00:11:27,030 --> 00:11:25,120 likes to operate is someone who's trying 85 00:11:30,059 --> 00:11:27,040 to read a book inside a car that is 86 00:11:31,439 --> 00:11:30,069 moving down a twisty country road ball 87 00:11:34,139 --> 00:11:31,449 would be bumped around all over the 88 00:11:36,239 --> 00:11:34,149 place of product focus on the books when 89 00:11:37,919 --> 00:11:36,249 really our brains and our vestibular 90 00:11:39,600 --> 00:11:37,929 apparatus would like to make reference 91 00:11:41,669 --> 00:11:39,610 to the X the world at that we see 92 00:11:43,230 --> 00:11:41,679 outside the window and as you know 93 00:11:45,600 --> 00:11:43,240 several people who try to read books 94 00:11:49,439 --> 00:11:45,610 inside moving cars become motion sick as 95 00:11:52,289 --> 00:11:49,449 well what is interesting to dr. wat is 96 00:11:55,199 --> 00:11:52,299 that astronauts tend to inadvertently 97 00:11:56,610 --> 00:11:55,209 develop a torso rotation motor strategy 98 00:11:59,549 --> 00:11:56,620 as well during the first couple of days 99 00:12:01,379 --> 00:11:59,559 of spaceflight and we probably do this 100 00:12:03,710 --> 00:12:01,389 to try to minimize our symptoms of 101 00:12:07,439 --> 00:12:03,720 motion sickness but in fact we might be 102 00:12:10,019 --> 00:12:07,449 exacerbating the symptoms the doctor 103 00:12:11,850 --> 00:12:10,029 Watts torso rotation experiment study on 104 00:12:14,549 --> 00:12:11,860 the life and microgravity Space Lab 105 00:12:17,039 --> 00:12:14,559 mission we are going to be measuring our 106 00:12:20,199 --> 00:12:17,049 eye movements with special electrodes 107 00:12:24,249 --> 00:12:20,209 that we apply to our faith 108 00:12:29,679 --> 00:12:24,259 the special velocity rate center that we 109 00:12:32,280 --> 00:12:29,689 rigidly fixed to the top of our head it 110 00:12:34,809 --> 00:12:32,290 also will be measuring our torso 111 00:12:36,999 --> 00:12:34,819 movements as well with the special 112 00:12:42,369 --> 00:12:37,009 backpack accelerometer which is fixed to 113 00:12:44,290 --> 00:12:42,379 our back after the flight is over dr. 114 00:12:46,269 --> 00:12:44,300 what is going to compare our eye 115 00:12:48,129 --> 00:12:46,279 movements to our head movements and our 116 00:12:49,840 --> 00:12:48,139 head movements to our chest movements 117 00:12:52,329 --> 00:12:49,850 and he'll be looking for any evidence 118 00:12:54,160 --> 00:12:52,339 that we might have adopted some torso 119 00:12:56,859 --> 00:12:54,170 rotation motor strategy during this 120 00:12:58,449 --> 00:12:56,869 flight will be doing this experiment was 121 00:13:00,489 --> 00:12:58,459 early in the mission we've already done 122 00:13:02,559 --> 00:13:00,499 it exactly towards the middle of the 123 00:13:05,109 --> 00:13:02,569 flights a couple of days and again 124 00:13:08,379 --> 00:13:05,119 towards the last day or two of the space 125 00:13:10,509 --> 00:13:08,389 mission if it turns out in fact that 126 00:13:12,850 --> 00:13:10,519 we'd have a dot to torso rotation motor 127 00:13:14,439 --> 00:13:12,860 strategy during the flight which might 128 00:13:16,449 --> 00:13:14,449 cause symptoms of motion sickness 129 00:13:18,730 --> 00:13:16,459 that'll be relatively easy to train 130 00:13:22,290 --> 00:13:18,740 future astronauts to avoid this type of 131 00:13:25,150 --> 00:13:22,300 motor strategy or to pre adapt them to 132 00:13:26,980 --> 00:13:25,160 the atypical movement environment or in 133 00:13:29,980 --> 00:13:26,990 a ground-based laboratory prior to 134 00:13:32,619 --> 00:13:29,990 flight well that's what the torso 135 00:13:35,049 --> 00:13:32,629 rotation experiments is all about if you 136 00:13:37,720 --> 00:13:35,059 see us in downly video over the next few 137 00:13:40,989 --> 00:13:37,730 days wearing strange-looking apparatus 138 00:13:42,579 --> 00:13:40,999 on our head or on our chest you know 139 00:13:44,379 --> 00:13:42,589 that will be just checking out to see 140 00:13:46,989 --> 00:13:44,389 that whether or not we are trying to 141 00:13:48,819 --> 00:13:46,999 unconsciously suppress the normal way 142 00:13:51,730 --> 00:13:48,829 that our vestibular apparatus likes to 143 00:13:54,100 --> 00:13:51,740 operate well that's it today from the 144 00:13:56,259 --> 00:13:54,110 space shuttle columbia tune in tomorrow 145 00:14:46,470 --> 00:13:56,269 to learn what are the other exciting 146 00:14:53,590 --> 00:14:49,390 now in view of from Columbia the outer
