Okay, so we are given the situation that a stroke patient, so a stroke victim and what happened here that it have the ability to move, so ability to move the left side of body, left side of body is lost.
00:22
So, it is lost while it still have reflexes on that side, so reflexes are still present on that side, present on that side.
00:37
Why? which part of brain is involved in this mechanism? so, mostly this mechanism is done by this motor cortex, so it is because of the affected motor cortex and its associated pathways, so its associated pathways.
00:58
So what we have here is that if there is motor cortex in the right hemisphere, so motor cortex in right hemisphere, right hemisphere and in this right hemisphere motor cortex what we have is due to crossing over of nerve fibers, so crossing over of nerve fibers, it can also control the left side of the body, so left side of body can also be controlled, can also be controlled.
01:40
So this is usually what causes the left side body reflexes.
01:45
So, a stroke occurs when, so if we discuss about the stroke, so if there is a disruption of blood flow, so there is a disruption of blood flow during a stroke to any particular area, any area in our body and basically mainly the brain, so any area of brain and this lead to damage of brain, so damage of that area...
