There are several segments in this CD. The first segment is entitled Voice Recognition and here what you\u2019re looking at is our testing of the newborn\u2019s ability to discriminate mother\u2019s voice from a stranger\u2019s voice. So in the beginning what we\u2019re doing is putting on electrodes, put on the baby\u2019s head and then we place a small ear insert into the baby\u2019s ear while the baby is in a light state of sleep. And then what the baby hears is their mother or a stranger saying a simple word like \u2018hi baby\u2019. So they hear \u2018hi baby\u2019 by mom and \u2018hi baby\u2019 by a stranger. And we present this about 100 times, maybe 50 times each and that entire time we\u2019re recording the baby\u2019s brain activity. And in one segment of the CD you can see on a blue screen the baby\u2019s brain activity going up and down like that. And the goal of that work is not just to look at what are the neural systems involved in recognizing mom\u2019s voice, but as well we\u2019re looking at a clinical population of babies who we think have had damage to the part of the brain involved in memory who may not have benefited from the experience of hearing their mother\u2019s voice and therefore may not recognize their mother\u2019s voice at birth. <\/p>\n\n\n\n
Now in the next segment which is called Face Recognition. What you see us doing there something comparable to what we saw in the newborn. This is a 6-month-old baby. We place a net of electrodes on the baby\u2019s head and then what we\u2019re doing is showing the baby pictures of faces and we want to know can they recognize a face they\u2019ve seen before from a novel face. And so again we\u2019re recording brain activity and again on the screen you can see a picture of the baby\u2019s EEG. And the goal of that work is to look at the neuro correlates involved in discriminating one phase from another phase. <\/p>\n\n\n\n
This is an older child. This is a 4-year-old entitled Emotion Recognition. Again we\u2019re recording brain activity except this time we\u2019re showing the child different pictures of facial expressions and we want to know, a. does their brain activity show that they can discriminate one expression from another, and b. does their brain show unique patterns of brain activity to some expressions rather than others. For example in some of our earlier work we demonstrated that anger expressions show a particular aspect of changes in brain activity that we don\u2019t see with other facial emotions. So the goal of that work is to look at the neuro correlates of recognizing emotion. <\/p>\n\n\n\n
And finally in the last segment entitled FMRI we\u2019re showing how we actually conduct functional magnetic resonance imaging studies. This is an 8-year-old child where she\u2019s brought into the scanner room and you can see what the tunnel looks like, the scanner. She hops up on the bed which goes up and then the child slides into the tunnel and then she\u2019s given a button box and what happens is that on the screen in front of her we\u2019re showing different patterns and she has to push a button that corresponds to which pattern she\u2019s seen before and which is novel. And so all she\u2019s doing is pushing a button that corresponds to whether she\u2019s seen one of those patterns before and which one she hasn\u2019t seen before. And during that entire time we\u2019re taking very detailed pictures of her brain. So we\u2019ll know precisely what part of the brain was involved in performing our task. And that whole test will take about 20 minutes. <\/p>\n","protected":false},"excerpt":{"rendered":"
